6. Replacing a USF Module
Follow the procedure described below to remove and replace a defective USF Module. Since no
electrical components are mounted on most USF rear modules, it is possible to recover proper operation
by replacing front modules.
NOTE
When both front and rear module are to be replaced, make sure to replace the rear module after
pulling out the front module.
IMPORTANT

Beware of the occurrence of electrical breakdown in USF Modules.

Wear an antistatic wrist strap or equivalent material to equalize the electrical potential of the
USF-
212S unit and the worker’s body. Do not touch the PCB wiring or parts legs directly with your
fingers while working.

Each USF Module can be installed and uninstalled while the power is on in case of emergency.
Shut down the power for non-emergency work.

When installing/uninstalling the front module while the power is on, the front panel will be open
state. The fan will stop during the procedure, so it is essential to complete the installation within a
short period and to close the front panel immediately.

Be sure to shut down the power to install and uninstall a control module.
The procedure for replacing a module in Slot 4 is described below as an example.
6-1. Removing the Front Module

"Slot Number.”
3. Slide the module out using the grab handle.
6-2. Removing the Rear Module
IMPORTANT
Always remove the front module first, then the rear module without exception.
1. Slot 4 is the bottom slot in the left block of the rear panel. Refer to Sec. 4-5.
"Slot Number”
2. Loosen the screws on both ends. Secure the rear module while loosening the screws in order
