{ Danger!
Hazardous voltage on the power connections even when disconnected from
mains: residual voltage >60 V!
Before working on the power connections, always disconnect the drive
component from the mains and wait until the motor is at standstill.
Verify safe isolation from supply!
( Stop!
Electrical connections must be carried out in accordance with the national and
regional regulations!
ƒ The connection must ensure a permanent and safe electrical supply, i.e.
– no loose wire ends,
– use assigned cable end fittings,
– establish a safe PE conductor connection,
– Tighten the plug−in connector to the limit stop.
ƒ The smallest air gaps between uncoated, live parts and against earth must not fall
below the following values:
Minimum requirements for basic
insulation according to IEC/EN
60664−1 (CE)
Higher requirements for UL design Motor diameter
3.87 mm 6.4 mm < 178 mm
ƒ All unused cable entries must be sealed against dust and water.
Voltage supply
ƒ Inverter−optimised motors
– must be supplied by inverters.
– connect the encoders mounted to the motor with the corresponding connections
of the inverter.
ƒ Holding brake (as option)
