B)
Use only the supplied motor cable for motor leads, be sure to attach all four wires — three
for power, one for ground. The 25 foot cable is recommended to prevent voltage and
frequency fluctuations, which could cause the motor to malfunction and/or be
damaged. Consult the factory if a longer cable is required.
C)
Route motor cable away from all other power and control cables. Keep motor cable at
least 6 inches away from input power and control wiring. If the motor cable must cross
power cables or other motor control cables, make sure they do so at 90 degree angles to
minimize interference. Avoid long parallel runs to prevent signal crossover.
D)
Correctly install supplied cable glands at both ends of the motor cable (see Figure 5).
i)
Take the cable gland apart and slide the gland nut over the end of the cable,
threads facing the cable end.
ii)
Slide the plastic and rubber cable gland insert over the end of the cable, with
the larger end toward the middle of the cable.
iii)
Strip the outer insulation of the cable back approximately three inches, leaving
approximately half an inch of metal and foil braid sticking out past the outer
insulation.
iv)
Slide the cable gland insert up the cable until it is flush with the outer insulation.
v)
Peel the foil and braid insulation back and fold it down over the cable gland
insert.
vi)
Cut off any inner (plastic) insulation that remains.
vii)
Slide the threaded part of the cable gland over the end of the cable, long side
down. Work it down over the insert until only the “fingers” of the insert are visible,
turning either piece as necessary to ensure a proper fit.
viii)
Slide the gland nut up and tighten it securely onto the gland.
E)
Connect the ground wire to the green screw located inside of the motor junction box.
