Page 16: Caution, Warning
2.4.2.2 Grounding Using Shielded Cable
Earthing (grounding) clamps are provided for motor wiring
(see Illustration 2.7).
Illustration 2.7 Grounding with Shielded Cable
2.4.2.3 Grounding Using Conduit
CAUTION
GROUNDING HAZARD!
Do not use conduit connected to the drive as a
replacement for proper grounding. Ground currents are
higher than 3.5mA. Improper grounding can result in
personal injury or electrical shorts.
Dedicated grounding clamps are provided (See
Illustration 2.8).
Illustration 2.8 Grounding with Conduit
1.
Use a wire stripper to remove the insulation for
proper grounding.
2.
Secure the grounding clamp to the stripped
portion of the wire with the screws provided.
3.
Secure the grounding wire to the grounding
clamp provided.
2.4.3 Motor Connection
WARNING
INDUCED VOLTAGE!
Run output 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. Failure to
run output motor cables separately could result in death
or serious injury.
