Use these procedures when mounting the module: 

Use horizontal or vertical mounting with a DIN rail that is 35 mm 

(1.4 in.) wide for placing the module in the control panel.

Leave at least 15 mm (0.6 in.) above and below the module for 

adequate ventilation and room for wiring.

Place all other heat sources an appropriate distance from the module 

to maintain the specified ambient temperature around the module.

While safety outputs are in an on state, the signal sequence shown in the figure is 

output continuously for fault diagnosis when output pulse testing is enabled. 

Confirm response time of device connected to safety outputs so the device does not 

malfunction due to off pulse.

Follow these guidelines when wiring the module: 

Do not route communication, input, or output wiring with conduit 

containing high voltage, referring to Industrial Automation Wiring 

and Grounding Guidelines, publication 1770-4.1.

Wire correctly after confirming the signal names of all terminals.

Note that stranded wire should be processed with insulation-covered 

ferrule (DIN 46228-4 standard compatible-type) at its ends before 

using for connection. 

Tighten screws for communication and I/O connectors correctly at 

0.25…0.3 N•m (2.21…2.66 lb•in)
