Installation
3.4.1 Requirements
WARNING
EQUIPMENT HAZARD!
Rotating shafts and electrical equipment can be hazardous.

All electrical work must conform to national and local
electrical codes. It is strongly recommended that instal-
lation, start up, and maintenance be performed only by
trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in three
separate metallic conduits or use separated shielded cable
for high frequency noise isolation. Failure to isolate power,
motor and control wiring could result in less than
optimum drive and associated equipment performance.
For your safety, comply with the following requirements.
Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
Run motor cables from multiple frequency
converters separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
Overload and Equipment Protection
An electronically activated function within the
drive provides overload protection for the motor.
The overload calculates the level of increase to
activate timing for the trip (controller output
stop) function. The higher the current draw, the
quicker the trip response. The overload provides
Class 20 motor protection. See 7 Warnings and
Alarms for details on the trip function.
Because the motor wiring carries high frequency
current, it is important that wiring for mains,
motor power, and control are run separately. Use
metallic conduit or separated shielded wire.
Failure to isolate power, motor, and control
wiring could result in less than optimum
equipment performance.
All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 3.5. See maximum fuse ratings in
8.2.2 CE Compliance and 8.2.3 Fuse Tables.

3.4.2 Earth (Grounding) Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the drive
properly in accordance with national and local electrical
codes as well as instructions contained within this
document. Ground currents are higher than 3,5 mA. Failure
to ground the drive properly could result in death or
serious injury.
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct grounding (earthing) of the
equipment in accordance with national and local electrical
codes and standards.
DET-759A
All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
GE recommends that all power connections be
made with a minimum 75° C rated copper wire.
Follow all local and national electrical codes to
ground electrical equipment properly
Proper protective grounding for equipment with
ground currents higher than 3,5 mA must be
established, see Leakage Current (>3,5 mA)
A dedicatedground wire is required for input
power, motor power and control wiring
Use the clamps provided with the equipment for
proper ground connections
Do not ground one drive to another in a "daisy
chain" fashion
