Wiring the thermistor relay(s) (oL505 and +2L505)
The external wiring of 2L505 (two thermistor relays) is shown below. For example,
one relay can be used to monitor the motor windings, the other to monitor the bearings.
The maximum contact load capacity is 250 V AC 10 A. For the actual wiring, see the circuit
diagram delivered with the drive.
