Field Wiring Guidelines

Overview

This section contains wiring guidelines and precautions.

Terminal Connector

With respect to the terminal connector, the guidelines are as follows:

Screw type, 17 pin, field connectors are included with this module and do not have to be ordered separately.
Note that pin 1 has been removed and the connector begins at pin 2.
18 pin connectors that are used on other Momentum I/O Bases, cannot be used with this module.

Busbar May Be Required

Depending on the type of field devices you are using, you may need a 1-row busbar. The following busbars are available from Schneider Automation.

Type	Part Number
Screw-in	170 XTS 006 01
Spring-clip	170 XTS 007 01

Mapping Terminal Blocks

CAUTION

POTENTIAL FOR SHORT CIRCUITS AND/OR POWER-UP SPIKES

Provide external fuses on the operating voltage to protect the module. Appropriate fuse values are shown in the wiring illustration. An unprotected module may be subject to short circuits and/or power-up spikes.

Failure to follow these instructions can result in injury or equipment damage.

The following table shows mapping terminal blocks and optional busbars.

Row	Terminal	Function
1	2,4,6,8,10,12	Relay Output 1 through 6 (normally open)
	17	module neutral
	18	120 to 230 VAC module power
2	2,4,6,8,10,12	Relay Output 1 through 6 (normally closed)
3	2,4,6,8,10,12	Relay Output Common 1 through 6
4	1 ... 18	Protective earth (PE)

Protective Circuit Required

When contacted switches are used on the input lines or when lines to the peripherals are very long, the outputs of inductive loads require protective circuitry with a clamping/suppressor diode. Install the protective circuit parallel to the operating coil.
