4.1 Safety Instructions

See Chapter 2 Safety for general safety instructions.
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equip-
ment capacitors even with the equipment turned off and locked out. Failure to
run output motor cables separately or use shielded cables or metal conduits
could result in death or serious injury.
• Run output motor cables separately, or
• Use shielded cables or metal conduits.
SHOCK HAZARD
The adjustable frequency drive can cause a DC current in the PE conductor.
Failure to follow the recommendation below means the RCD may not provide
the intended protection.
• When a residual current-operated protective device (RCD) is used for
protection against electrical shock, only an RCD of Type B is permitted on
the supply side.
Note: The adjustable frequency drive is supplied with Class 20 motor overload protection.
Overcurrent Protection
• Additional protective equipment such as short-circuit protection or motor
thermal protection between adjustable frequency drive and motor is required for
applications with multiple motors.
• Input fusing is required to provide short circuit and overcurrent protection. If not
factory-supplied, fuses must be provided by the installer. See maximum fuse
ratings in 8.8 Fuses and Circuit Breakers.
