2-18 Mounting and Wiring Your 1336 IMPACT Drive
The following table provides information about the
maximum/minimum wire size and maximum torque used for the
various frame sizes.
The drive connections are frame specific. Refer to the appropriate
chapter for the drive connections.
Selecting Your Motor Cables
You can select which type of cable you want to use with the 1336
IMPACT drive.
Unshielded Cable
For many installations, you can use unshielded cable as long as you
can separate it from sensitive circuits. As an approximate guide, allow
a spacing of 1 meter (3.3 feet) for every 10 meters (33 feet) of length.
In all cases, you need to avoid long parallel runs.
Unshielded cable should be 4-conductor with the ground lead
connected directly to the drive ground terminal (PE) and the motor
frame ground terminal.
Shielded Cable
You should use shielded cable if sensitive circuits or devices are
connected or mounted to the machinery driven by the motor. You
must connect the shield to the drive chassis. Make the connection at
both ends to minimize the external magnetic field.
If you use cable trays or large conduits to distribute the motor leads
for multiple drives, use shielded cable to reduce or capture the noise
from the motor leads and to minimize cross coupling of noise
between the leads of different drives. Connect to the ground (PE)
connections at both the motor and the drive end.

2 These configurations of TB1 are stud type terminations and require the use of lug
type connectors to terminate field installed conductors. Lug kits are available for use
with these configurations. Wire size used is determined by selecting the proper lug
kit based on the drive catalog number. Refer to Chapter 4 for information on lug kits.
