■The cabinet is only suitable for mounting on a concrete or other noncombustible surface.

■Maximum ambient temperature (Tma) of 46º C (115º F) permitted by manufacturer specification.

■All conduit hubs must be of Type 3R or equivalent to maintain the cabinet as Rainproof.

■It is essential to connect the cabinet to earth ground before connecting supply, high leakage current.

■All cabinet equipment cabling is to meet applicable NEC1and network communications standards.

Safety Precautions:

Note: In areas that utilize joint buried plant, and per company practice, test and verify that voltage is not

present on the cable shield. If voltage is present on the shield, stop work and notify supervision.

■Follow all product warnings and instructions as specified in this document, cabinet and equipment

labels inside the cabinet to reduce risk of fire, electric shock, and injury.

■Install all equipment and supplied hardware as specified in this document.

— Install only approved devices in the cabinet and do not drill, saw, or cut inside the cabinet.

— Never install cable, connectors, jacks in a wet location unless designed for wet locations.

— Never install electrical equipment during a thunderstorm, there is risk of electric shock.

— Never touch uninsulated live power wires or terminals, always disconnect from power first.

► CMC-21, 28, and 35 Cabinet Rack Unit (RU) Configurations

Table Bshows RU space allocated to a cabinet based on number of battery strings with remaining RU

space dedicated to cabinet equipment.

Note 1: The bottom two battery shelves for CMC-21 and CMC-28 cabinets are adjustable from 7 or 8RU,

and for a CMC-35 the bottom three battery shelves are adjustable from 7 or 8RU.

Note 2: All batteries must be of the same type and from same manufacturer. Do not mix battery types

from different manufacturers. Pole or wall / H-frame mounting a cabinet with batteries is limited to

two battery strings; CMC-21/28 cabinets only – CMC-35 is not suitable for pole or wall / H-frame.

► Door View Examples with Thermosiphon and Air Conditioner Units

Note: See Table A for CMC cooling configurations and cooling unit manual provided with the cabinet for

power, alarm, and network connections; operation, settings, and maintenance.

Door with Thermosiphon (T1-T3)

A thermosiphon (Figure 6) lowers the inside cabinet temperature by means of a refrigerant liquid that

absorbs heat from the interior heat exchanger of the unit and converts it to a gas. This exchange allows

the gas to move into the exterior heat exchanger where it is converted back into a liquid that delivers heat

out to exterior air.

■All units have a DC power input and alarm output terminal block and RJ45 ports.

Door with Air Conditioner: DC Power (D1-D7)

A CMC cabinet may utilize a DC unit per cabinet configuration and operating requirements defined by

customer, Table A.

■All units have power input and alarm terminal blocks, I/O and RJ45 ports, and an interface display.

► Door Clearances

Note: Figure 8 shows AC load center on cabinet right side to clarify door clearances. Optional AC load

center can be mounted per customer request on either side. However, AC load center should not

be installed on the left side for wall / H-frame mounting.

► Rear Panel Removal and Installation

Prior to panel removal or installation, use door key (Figure 11) that ships with cabinet to open or close

1/4-turn latches when removing or installing a panel, Figure 9.

Note: Rear panel has ground cable attached on the inside of the panel.

Removal and Installation (Figure 9)

■Removal

— Turn panel latches to open position and pull out top of panel first; then tilt panel out and pull up on

panel to remove the panel from the opening.

— To remove the panel from the cabinet, disconnect ground cable from the green connector shown

in Figure 9. Prior to replacing the panel, make sure to reconnect ground cable to green connector.

■Installation

— Tilt panel bottom in and insert bottom into cabinet; press into panel and close latches.

Figure 9. Rear Access Panel Removal and Installation, Ground Cable Disconnect

► Door Intrusion Alarm Switch

The light and door intrusion switches are on the top left corner of the doorframe inside the cabinet.

Connect the door alarm as required to an alarm center, Figure 10.
