A good example of recommended cable is Belden/E 295xx (xx determines
gauge). This cable has four XLPE insulated conductors with a 100% coverage foil
and an 85% coverage copper braided shield (with drain wire) surrounded by a
PVC jacket.
Other types of shielded cable are available, but the selection of these types may
limit the allowable. Particularly, some of the newer cables twist four conductors
of THHN wire and wrap them tightly with a foil shield. This construction
increases the cable charging current required and reduces the overall drive
performance. Unless specified in the individual distance tables as tested with the
drive, these cables are not recommended and their performance against the lead
length limits supplied is not known.
The table below describes the recommended shielded cables.

Contactors
A contactor or other device that routinely disconnects and reapplies the AC line
to the drive to start and stop the motor can cause drive hardware damage. The
drive is designed to use control input signals that will start and stop the motor. If
an input device is used, operation must not exceed four cycles per minute
maximum, or damage will occur to the drive precharge circuit.
The start/stop/enable control circuitry for the drive includes solid state
components. If hazards due to accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an additional stop circuitry may
be required to remove the AC line to the drive. An auxiliary braking method also
may be required.
