A trained engineer or maintenance staff should attach or detach the DC power supply
cable to or from the electrical power equipment. The terminals of the DC power supply
cable are connected to the electrical power equipment. Wrong handling of the DC
power supply cable can cause a fire or electric shock.
Prior to attaching or detaching the DC power supply cable, turn off the circuit breaker
of the electrical power equipment. Otherwise, an electric shock might result.
Cover the G and -48 V terminals of the DC power supply cable (on the electrical power
equipment side) with an insulation jacket. Otherwise, an electric shock might result.
