Place an insulation cover over the 0 V and −48 V terminals of a DC power cable
before using them. Using the terminals without an insulation cover could result in
fire or electric shock.
 Do not use a DC power supply with the cover of the terminal board

After attaching a power cable, attach the cover to the terminal board when using a
DC power supply. Using the power supply unit without the cover could result in
electric shock.
 Do not touch the terminal used to measure voltage.
A power supply unit has a terminal used to measure voltage. This terminal is used
for inspection before the unit is shipped from the factory. Customers must not use
this terminal. In addition, do not insert anything with a narrow tip, such as a pin or
paper clip, into the terminal. Doing so could result in fire or electric shock.
