• All the (3) terminal box openings are closed with the standard plastic plates
with the metric threads.
8
• The metal cable entry plate for UL installation has to be installed in place of
one of standard plastic cable entries provided with the default package. The
metal cable entry plate has three not-threaded openings: input line, motor and
I/Os and can be mounted only on left or right-hand side of the drive.

• Flexible or rigid cable conduit can be used.
• Use proper fittings to join and terminate rigid conduit tubing, and protect it
from damage too.
• The proper selection of electrical conduit materials, fittings, and installation
are important for safe electrical wiring.
10
• Setscrew fittings are commonly used with conduit; they provide weather tight
joints that are firm to keep the IP degree of the drive.
11
• Pass the cables (supply cable, motor cable, brake cable and I/O cables) through
the conduits (UL connections) or through the cable glands (IEC connections)
and cable entries.
12
• Detach the cable clamps and the grounding clamps.
13
Connect the stripped cables:
• Expose the shield of both cables in order to make a 360-degree connection with
the cable clamp (reverse the shield over the plastic cover of the cable and fix all
together).
• Connect the phase conductors of the supply and motor cables into their
respective terminals.
• Form the rest of the cable shield of both cables into “pigtails” and make a
grounding connection with the clamp. Make the pigtails just long enough to
reach and be fixed to the terminal - no longer.
