Fire Prevention; Lockout And Tagout Requirements - Advanced Energy AE 600 User Manual

Advanced Energy
Ensure phase cables run together through conduit and gland plates, which allows any
inductive currents produced to be cancelled out. Use proper torque values for
terminal lug mounting hardware.
A copper clad earth grounding electrode must be installed within three feet (one
meter) of the unit. The AC ground busbar located in the AC section, lower front
compartment, must be used as the single point connection to the earth grounding
electrode for the inverter system. For the convenience of installers, a DC ground bus
bar is provided. The DC and AC ground bus bars are solidly bonded together inside
the cabinet. If present, a DC Grounding Electrode Conductor (GEC) may be bonded
to the DC ground bar. Where permitted by NEC, a single conductor that meets all the
requirements of both DC GEC and AC equipment ground may be bonded to the AC
ground bar.
AC overcurrent protection for the utility interconnect (grid-tied) must be provided by
installers as part of the installation.

Fire Prevention

Care must be exercised when installing DC and AC connections within the inverter.
Follow all instructions in this manual to ensure proper and safe operation of this unit.
DANGER:
Risk of electrical shock. In the event of a fire, disconnect power to the
inverter and do not attempt to use a water based fire extinguisher. Utilize
only a Class C extinguisher rated for electrical fire.
DANGER:
Risque d'électrocution. Dans l'éventualité d'un incendie, débranchez
l'onduleur du secteur et n'utilisez pas d'extincteur à base aqueuse. Utilisez
uniquement les extincteurs de classe C conçus pour combattre les feux
électriques.

LOCKOUT AND TAGOUT REQUIREMENTS

To prepare the AE 500 unit for maintenance or troubleshooting, you must de-
energize and isolate the AC and the DC interface energy sources before working on
the unit.
