DANGER!
The user is responsible for conforming with all applicable
local, national and international codes. Wiring practices, grounding,
disconnects and overcurrent protection (fusing) are of particular
importance. Failure to observe this precaution could result in severe
bodily injury or loss of life.
DANGER!
The user is responsible for designing an adequate
Emergency Stop (E-Stop) circuit. It is not adequate to depend on the
drive enable for an E-Stop. a properly designed E-Stop circuit
should remove power from the drive and apply a brake to the motor
or load when necessary. Failure to observe this precaution could
result in severe bodily injury or loss of life.
Caution!
Do not tin (solder) the exposed leads on cables. Tinned
cables may loosen in screw terminal connections over time.
General Wiring Guidelines
It is always best to keep power wiring separate from control wiring.
Properly terminated shielded cables for control wiring will help
ensure minimal interference problems, but should be combined
with good wire routing practice to ensure optimum results.
Power and control wiring should be run in separate conduit or
wiring trays with as much separation as is practical to achieve.
When power and control cabling needs to cross, it should be done at
right angles.
Encoder and other control wiring can pick up interference from the
50/60Hz power itself or transient energy present on the power lines.
This transient energy is most often caused by relays and contactors,
other motors and their drives and devices (such as welders) found in
a typical industrial environment.
All power cables should be copper conductors rated 60° C minimum
and should be tighhtened to the terminal blocks with 9.0 in. •lbs of
torque.
