Motor Overload Protection; Technical Data - Phoenix Contact ELR H51-IESSC-24DC500AC-06 Handbuch

6.3. Motor overload protection

All safety-relevant functions are implemented by the hybrid motor starter, without external influences.
Special circuit technology is not necessary.
Wiring of the load current circuit should be realized as described in the examples provided. The module
current supply can however be directly connected to the voltage source, without the PSR safety relay. The
same is applicable for the control.
6.4. Motor with brake
If a motor with brake is connected (in the motor terminal board), the 400 V AC brake has to be connected
to the 2/T1 and 6/T3 connections. A 230 V AC brake must be connected with 4/T2 and the neutral point
of the motor.
Please note: The motor current monitoring must be increased by the value of the brake (nominal
brake current), (see item 5.3, page 20).
