Best Practices Chapter 4

Armored Cable

Armored cable can be terminated in a similar manner to standard cable.

Conductor Termination

Terminate power, motor, and control connections to the drive terminal blocks.
User manuals list minimum and maximum wire gauges, tightening torque for
terminals, and recommended lug types if stud connections are provided. Use a
connector with three ground bushings when you use a cable with three ground
conductors. Follow applicable electric codes when bending radii minimums.

Power TB

Power terminals are normally fixed (non pull apart) and can be cage clamps,
barrier strips, or studs for ring-type crimp lugs depending on the drive style and
rating. Cage clamp styles can require a non-standard screwdriver. Crimp lugs
require a crimping tool. On smaller sizes, a stripping gauge is sometimes provided
on the drive to assist in the amount of insulation to remove. Normally the
three-phase input is not phase sensitive. That is, the sequence of the A, B, and C
phases has no effect on the operation of the drive or the direction of motor
rotation.

Control TB

Control terminal blocks are either pull apart or fixed (non pull apart). Terminals
are either spring clamp type or barrier strip. A stripping gauge is sometimes
provided on the drive to assist in the amount of insulation to remove. Some
control connections, such as analog input and output signals, are sensitive to
polarity. Consult the applicable user manual for correct connection.

The Tek-Mate Fast-Fit cable clamp by O-Z/Gedney is

a good example of an armored cable terminator.
