2-16 Mounting and Wiring Your 1336 IMPACT Drive
Making the Encoder Connections
If you want to use an encoder, you need to use an L Option board. If
you do not have an L Option board, you cannot use an encoder.
To make the encoder connections, you must:
1. Route the connections in grounded steel conduit or shield cable in
a wire tray. If cables are run in a wire tray, you must separate the
signal and encoder wire from the power cables, preferably with a
steel divider.
2. Ground the conduit at both ends.
3. Ground the cable shield only at the drive.
For additional information about using an encoder, refer to Chapter 5,
Using the L Option.
Grounding the Discrete Control and Signal Wiring
To ground the control and signal wiring, you need to:
1. Ground the 0V or ground terminal at the equipment (source) end,
not the drive end. You must ground all control and signal wiring
at a single point in the system, remote from the drive.
2. Ground the shield if you are using shielded control and signal
wires.
Connecting the TE Terminal Block
The TE terminal block is used for all control signal shields within the
drive. Refer to the frame specific chapters for the TE terminal block
location.
The TE terminal block accepts wire with the following specifications:
Grounding the Safety Ground (PE)
Most codes require a safety ground. You can connect the ground bus
to adjacent building steel (such as a girder or joist) or a floor ground
loop, provided that the grounding points comply with your national
(such as NEC), regional, or local regulations.
