5. USF Module Installation
USF Modules can be installed into any free slot. If multiple free slots exist, do not install modules
side-by-side but leave slots open to prevent overheating and facilitate signal connection from the rear
panel.
NOTE

USF Modules come as front and rear sets. Be sure to install set modules into the same (front and
rear) slot locations.

Always install the rear module first, then the front module.

Install blank panels over free slots to prevent foreign material from entering and overheating the
chassis.
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 installing the USF module in SLOT1 is described below as an example.
5-1. Installing of a USF Rear Module
