Wire Group Numbers
The following chart identifies general wire categories that will be
encountered when installing the 1336 and other AC drives. Each category
has an associated wire group number that is used in the following sections
to identify the wire to be used. Application and signal examples along with
the recommended type of cable for each group is provided. A matrix
providing the recommended minimum spacing between different wire
groups run in the same tray or separate conduit is also provided.

All signal wiring must be run in separate steel conduit.
A wire tray is not suitable.
The minimum spacing between conduit containing
different wire groups is 3.00 inches (78.2 mm).

Refer to precautions in General Wiring Procedures concerning multi-conductor cables.
Belden 8760 — 18 AWG, twisted pair, shielded.
Belden 8770 — 18 AWG, 3 conductor, shielded.
Belden 9460 — 18 AWG, twisted pair, shielded.
Note 1 Steel conduit is recommended for all 1336 power or control wiring and required for all 1336 signal wiring. All input and output power wiring,
control wiring or conduit should be brought through the drive conduit entry holes provided. Use appropriate connectors to maintain the
environmental rating of the enclosure.
Note 2 Spacing between wire groups is the recommended minimum for parallel runs of 200 feet or less.
Note 3 All shields for shielded cable must be grounded at the drive end only –– Terminal 3 or 4 of TB2 –– The other end must be insulated and remain
floating. Shields for cables from one enclosure to another must be grounded only at the enclosure nearest the drive. If splicing of shielded cables is
required, the shield must remain continuous and insulated from ground.
Note 4 AC and DC circuits must be run in separate conduit or trays.
Note 5 A voltage drop in motor leads may adversely affect motor starting and running performance. Installation and application requirements may dictate
that larger wire sizes than indicated in the NEC guidelines be used.
