Switching of inductive power
Inductive loads need additional measures for spark suppression. Diodes for DC
voltage and varistors / RC elements for AC voltage are suitable. Some DC coil
contactors contain rectifiers which suppress sparks perfectly.
Relay contact service life
Mechanical 500 000 switching cycles
Electrical (250 V AC):
0.5 A: 100 000 cycles
1.5 A 50 000 cycles
Internal clearance and creepage distances relay contacts to 24 V circuits
> 5.5 mm (safety insulation up to 250 V AC)

Supply power down/up, behaviour: Valid for all motor control functions,
except transparent and overload relay.
Whenever the supply voltage of the UMC is switched off and on, the starting of
the motor needs a new RUN signal.
