Note: Ideally the power should be turned off to the
power supply before doing any maintenance. It
must be noted that when the fuse is either blown or
removed the CPU will go into a normal shutdown.
Replacing the fuse with the power off guaranties
the system will come up in an orderly fashion. Re-
placing the fuse while power is still on could create
unpredictable restart issues.

2500C-PS-120V-35 120VAC 35 Watt Power Supply
Warning:
Disable all power to the base before installing
or removing the power supply. Failure to do so
could cause damage to the equipment or injury
to personnel.
2500C Compact Power Supplies
are always located in the left most
Caution:
Do not attempt to operate the 2500C-PS-120V-
35 out of the Voltage Operating Ranges speci-
fied. Damage to the Power Supply could occur
if out of range power input is applied.
Installing Power Wiring
Use the following steps for installing and removing the 2500C-PS-120V-35 Power Supply from the 2500C Chassis.
1. Position the power supply so that the bezel is facing you.
2. Grasp the top and bottom of the power supply
3. Carefully slide the power supply into the left most slot in the base until it engages into the backplane connector.
4. Strip power wiring back, insert the wire into the wiring connector as shown above, then tighten screws
5. Check to make sure the power input wires are securely inserted and the fastened in the wiring connector.
6. Insert and tighten down the 3 pin removable wiring connector.
7. Be sure to tighten the top and bottom bezel screws completely.
8. Once all the chassis modules including controllers and IO are inserted then you may apply power to the power supply
inputs.
To remove the power supply, remove power from the power input by removing the power wiring connector or turning off the
power source, loosen the bezel screws, and pull the power supply forward out of the chassis until it clears the chassis.
