WARNING
Mandatory ActionProhibitive ActionWarning, Caution
Indicates a condition that can cause death or serious injury if
not avoided.
Indicates a condition that can cause minor or moderate injury if
not avoided.
WARNING
Turn off the power at the
switchboard before beginning
the installation.
Fire, electrical shock or serious
injurycan result if the power is
left on or is applied while the
equipment is being installed.
Be sure that the power supply is
compatible with the voltage
rating of the equipment.
Connection of an incorrect power
supply can cause fire or damage
the equipment.
Use only the specified power
cable.
Fire or damage to the equipment
can result if a different cable is
used.
Ground the equipment to prevent
electrical shock and mutual
interference.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury
can occur.

OVERVIEW
The PR-241 is a unit integrates the functions of our AC/DC power supply units and rectifiers
listed below.
• AC/DC power supply unit PR-240, PR-300
• Rectifier unit RU-1746B-2, RU-3423, and RU-3424.
Important notices
The specifications of PR-241 have been changed to be compatible with DC bypass. The DC
compatible unit has a white dot as shown in the figure below. Up to two units can be con-
nected in parallel, the same as the previous specifications. However, the DC bypass com-
patible units cannot be connected in parallel with the DC bypass non-compatible units.
The differences from the conventional PR-241 (DC bypass non-compatible units) are as
shown in the table below.

SYSTEM CONFIGURATION
1. MOUNTING
This unit can be mounted on a desktop or bulkhead. Refer to outline drawing in the back of
this manual when you mount the unit.
When mounting the unit, pay attention to the following points.
• This unit has the following ingress-proof ratings: IP22 for desktop mounting, IP20
for wall mounting.
• When using in dual, do not input from multiple AC power supplies or batteries. Due
to the difference in the load characteristics of the battery and the PR-241, it may not
function as a power supply.
• When using in dual, do not stack the units. Always leave sufficient space between
the units to allow for air-flow and prevent heat build-up. See the outline drawing at
the back of this manual for minimum distances required.
• Turn off the power at the switchboard before beginning the installation.
• Referring to the outline drawings at the back of this manual, leave sufficient room
for service and maintenance.

The mounting procedure is as follows:
1. Referring to the outline drawing at the back of this manual, make four pilot holes
for self-tapping screws (4x16, local supply) in the mounting location.
2. Place the unit in a fixed position and align the screw holes.
3. Secure the unit by tightening the self-tapping screws.
2. WIRING FOR SINGLE USE
Fabrication
Use the following crimp-on lugs (local supply) and cables or equivalent (local supply) for
connection with the power supply unit.
• Power cable: TPYC-1.5, DPYC-1.5
• Crimp-on lugs (see below figure): FV2-P4K
Self-tapping
screws (4x16, 4 pcs.)
CAUTION
To prevent noise and interference,
separate the AC IN, DC IN and DC OUT
cables of this unit from connected
equipment's cables.

Note 1: To prevent current imbalance, the input and output cables indicated in the be-
low figures must be the same length and the difference in the resistance value of the
cables must be 3 mΩor less.
Note 2: When backing up power from the battery, signal cable connection is not re-
quired.
3. Attach the terminal cover to the unit and fasten the screws removed at step 2.
Note: The terminal cover also acts as protection against water damage and must be
installed.
