5.2 Precautions before starting an installation
Do not put your hands inside the device carelessly. The components might cause
an injury.
For the EPU, use blank panels to cover the slots that do not contain power supply
modules. If you use the switch without attaching the blank panel, you might be
injured by a moving part. In addition, if foreign objects fall into the switch, the switch
might no longer work properly.
CAUTION
Prior to mounting/dismounting the power supply module, turn off the switch of it.
CAUTION
Make sure to wear an antistatic wrist strap. Handling the device without an
antistatic wrist strap might damage the device due to an electrostatic discharge.
CAUTION
Do not touch the parts or the soldered surfaces on the power supply module. For
storage, put the module in an antistatic bag.
