General safety guidelines
This equipment is a relatively complicated apparatus. During rigging, installation, operation,
maintenance, or service, individuals may be exposed to certain components or conditions including,
but not limited to: heavy objects, refrigerants, materials under pressure, rotating components, and
both high and low voltage. Each of these items has the potential, if misused or handled improperly,
to cause bodily injury or death. It is the obligation and responsibility of rigging, installation, and
operating/service personnel to identify and recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure to comply with any of these requirements could
result in serious damage to the equipment and the property in which it is situated, as well as severe
personal injury or death to themselves and people at the site.
This document is intended for use by owner-authorized rigging, installation, and operating/service
personnel. It is expected that these individuals possess independent training that will enable them
to perform their assigned tasks properly and safely. It is essential that, prior to performing any
task on this equipment, this individual shall have read and understood the on-product labels, this
document and any referenced materials. This individual shall also be familiar with and comply
with all applicable industry and governmental standards and regulations pertaining to the task in
question.

WARNING
External wiring, unless specified as an optional connection in the manufacturer’s product line, is not
to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls
and any external wiring must not be installed inside the micro panel. All wiring must be in accordance
with the manufacturer’s published specifications and must be performed only by a qualified electrician.
The manufacturer will NOT be responsible for damage/problems resulting from improper connections
to the controls or application of improper control signals. Failure to follow this warning will void the
manufacturer’s warranty and cause serious damage to property or personal injury.
Changeability of this document
In complying with the manufacturer's policy for continuous product improvement, the information
contained in this document is subject to change without notice. There is no commitment to update
or provide current information automatically to the manual or product owner. Updated manuals, if
applicable, can be obtained by contacting the nearest sales office.

Installation
CAUTION
Do not enter Setup mode when powering on the VFD.
Do not change parameters 4009 and 4011 for the VAV option on DSH, DSV, or CSV C-gen units. These 2
parameters are used for B-gen units only (Simplicity 1A not SEC.)
For these units, use the Smart Equipment (SE) controller to set the VAV setpoint.
WARNING
Prior to installing or servicing the unit, ensure proper lockout/tagout (LOTO) procedures are followed
per OSHA safety regulations (29 CFR 1910.147 and 29 CFR 1910.333). Failure to disconnect power supply
may result in electrical shock or even death.
Always wait for at least 5 minutes after disconnecting the power before servicing the unit.
Background
All D-Series and C-Series units that are 8 tons or larger have a Variable Frequency Drive (VFD)
installed.
There are 2 controlled fan method VFD options for D-series. SZVAV differential pressure transducer
and IntelliSpeed™ (2, 3 or 4 speed) fan control.
There are 3 controlled fan method VFD options for C-series. SZVAV, MZVAV differential pressure
transducer and IntelliSpeed™ (2 speed) fan control.
Note:
Refer to the nomenclature breakdown in the appropriate DSV, DSH, or CSV Installation,
Operation, and Maintenance (IOM) manual and also the nameplate of the unit to determine
the Controlled Fan Method. The tenth digit of the nomenclature (ID Motor) identifies which
method the unit has.
Use the nomenclature to select the low ambient condenser option.
SZVAV option in D-Series / MZVAV option in C-Series
For C/D-Series units with the SZVAV or MZVAV option, the supplied VFD allows the operator to
set the external static (0.0–5.0 "WC), as measured from a supply duct location determined by
field installer and/or as per field specifications. The VFD controls the frequency (speed) of the
evaporator fan motor in order to meet the desired external static (ESP) setpoint. The VFD controls
amp draw of the motor and does not allow the motor draw more than FLA amps.
Note: Do not run the evaporator fan motor below 30Hz, as coil freeze-up and nuisance
lockouts may occur. The unit is factory set to minimum 30 Hz output with the exception of the
Low Ambient Condenser VFD, which is set to 15 Hz.
Note: The unit does not carry a failsafe circuit to bypass the VFD and run the evaporator fan in
the event of a VFD malfunction.

Johnson Controls
The unit does not carry a failsafe circuit bypass for the evaporator fan in the event of a VFD
malfunction. During a VFD failure, the evaporator fan becomes nonoperational. If there is a
demand for cooling, the unit compressors continue to run until the low pressure safety switch trips.
Factory shipped
Units that are 8 tons or larger ship with a VFD controller factory installed and wired in the
evaporator (air handler) corner post. See the dimensional drawings in the IOM for the location.
DSV models
The DSV units ship factory split (condenser and evaporator) and require assembly in the field. The
motor is pre-wired to the VFD in the factory.
To assemble the DSV model in the field:
1. Plug the low voltage wiring, shipped wired to the VFD, to the SE Controller.
2. Connect the low voltage wires from VFD unit (24VDC) to the evaporator fan VFD relay
(EVFDR). The EVFDR relay acts as a switch to turn on the VFD.
3. Connect two 1/4 inch Q.C. to common and normally open positions (red wire to “C,” orange
wire to “NO”).
The VFD switch runs on 24VDC.
CAUTION
Do not cross 24VAC and 24VDC wiring on EVFDR relay.
DSH models
The VFD controller on DSH units is factory wired. The evaporator fan power conductors are factory
wired to the distribution block. The control wiring for field split applications needs to be field
provided and routed from condenser to evaporator.
CSV models
The CSV units ship factory assembled except for the CSV240 which can optionally be split and the
CSV300C which ships split (condenser and evaporator) and requires assembly in the field. The
motor is pre-wired to the VFD in the factory.
To assemble the CSV300C model in the field:
1. Plug the low voltage wiring, shipped wired to the VFD, to the SE Controller.
2. Connect the low voltage wires from VFD unit (24VDC) to the evaporator fan VFD relay (EVF-
DR). The EVFDR relay acts as a switch to turn on the VFD.
3. Connect two 1/4 inch Q.C. to common and normally open positions (red wire to “C,” orange
wire to “NO”).
The VFD switch runs on 24VDC.

CAUTION
Do not cross 24VAC and 24VDC wiring on EVFDR relay.
VAV units
Differential pressure transducer
Figure 1: Label on unit/VFD for VAV with pressure transducer
For VAV option units, the differential pressure transducer (0-5" W.C) is factory wired and mounted
inside the VFD control box. The transducer senses gage pressure (static) and converts this pressure
difference to an analog signal. The unit is wired for 0–5VDC output for DSV, DSH, or CSV C-gen
units.
The transducer is supplied with two 1/4-inch OD pressure fittings and accepts field provided 1/4-
inch push-on tubing for lengths of up to 300 feet. The positive (HIGH) and negative (LOW) pressure
ports are indicated on the transducer. Connect unit RETURN AIR tubing to negative (LOW) fitting
and SUPPLY AIR tubing to positive (HIGH) fitting.
Note:
Do not enter Setup mode when powering on the VFD.
Do not change parameters 4009 and 4011 for the VAV option on DSH, DSV, or CSV C-gen units.
These 2 parameters are used for B-gen units only (Simplicity 1A, not SEC.)
For these units, use the Smart Equipment (SE) controller to set the VAV setpoint.
CAUTION
Do not adjust the VFD setpoint to greater than the maximum design pressures of the duct system or
the unit.
Note:
• Only use 24VAC from SE controller to the differential pressure transducer (Term. Exc.)
