Safety-3
Ensure that the capacity for incoming current to the distribution board is greater than
the operating current of the power facility circuit breaker.
Ensure that the capacity for incoming current to the distribution board is greater than the operating
current of the power facility circuit breaker. If it is not, the power facility circuit breaker might not
operate properly in the event of a failure, which might result in a fire.
Ground the Device.
When the Device is connected to a DC power supply unit, always connect the ground terminal for
proper grounding. Failure to do so might not only result in electric shock, but it might also introduce
unwanted electrical noise that might cause a Device failure.
Connecting and disconnecting a DC power cable must be performed by a trained
technician or maintenance personnel.
Connecting and disconnecting a DC power cable must be performed by a trained technician or
maintenance personnel. Terminal connections are required for connection of the DC power cable.
Incorrect handling of the DC power cable might result in a fire or electric shock.
Turn off the circuit breaker on the power facility before connecting or disconnecting the
DC power cable.
Turn off the circuit breaker on the power facility before connecting or disconnecting the DC power
cable. If you perform an operation with the circuit breaker turned on, it might result in electric shock.
Place a terminal cover over the 0 V and
−
48 V terminals of DC power cables
When using a DC power cable, place a terminal cover over the 0 V and
−
48 V terminals. Using the
terminals without a terminal cover might result in electric shock.
When using a DC power supply unit, do not use the terminal board with its cover removed.
When using a DC power supply unit, place a cover over the terminal board after connecting the power
cable. Using the terminal board without a cover might result in electric shock.
