Power Connections

LD-Series and Y-Series Motor Cables

LD-Series and Y-Series motors have a short “pigtail” cable which
connects to the motor but is not shielded. These motor power cables
have a 6 inch shield termination wire with a ring lug which should be
connected to the closest earth ground. The shield termination wire
may be extended to the full length of the motor pigtail if necessary, but
it is best to connect the supplied wire directly to ground without
lengthening.

Motor Overload Protection

The drive utilizes solid state motor overload protection which
operates:

within 8 minutes at 200% overload

!

Intro

ATTENTION: High voltage may be present on the ter-
minals of the drive. Remove power and disconnect the
power cable before making or removing any connection.

!

Intro

ATTENTION: Do not tin (solder) the exposed leads on
cables. Solder contracts over time and may loosen the con-
nection.
