damage the device.
→ Make sure that the cable end is connected in a dry
environment.
The control voltage circuit is not electrically isolated. Connect
the device only to circuits that can be switched off using an allpole disconnecting switch.
4.2.1 Prerequisites
; Check whether the data on the type plate agree with the connection
data.
; Before connecting the device, ensure that the supply voltage matches
the operating voltage of the device.
; Only use cables designed for current according to the type plate.
For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor crosssection.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
4.2.2 Idle current
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and interference immunity), idle
currents in the mains cable can be measured even when the
motor is at a standstill and the mains voltage is switched on.
● The values lie in a range of typical < 250 mA.
● The effective power in this operating state (readiness for operation) is
simultaneously at typical < 4 W.
4.2.3 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connection via plug
4.3.1 Preparing connection lines for the connection
