Wiring example 1 (Fig. 5)
• If the feedback circuit
is not required, establish a bridge.
When the AZR 31S1 safety-monitoring module is used, an
automatic restart after a shutdown in case of emergency
must be prevented by the upstream control to EN 60204-1
paragraph 9.2.5.4.2 and 10.8.3.
Wiring example 2 (Fig. 6)
• The control is realised through 3 phases of the AC network.
• Wire breakage between the motor windings is detected.
• Control category: 4 - PL e to DIN EN ISO 13849-1 possible

Wiring example 4 (see fig. 8)
• Single-channel control
• Suitable for increase in capacity or number of contacts by means
of contactors or relays with positive-guided contacts.
• If the feedback circuit
is not required, establish a bridge.
