NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected in a dry
environment.
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
4.2.1 Prerequisites
; 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.
Earth wire contact resistance to EN 61800-5-1
Compliance with the impedance specifications to EN 61800-5-1 for the
protective earth circuit must be verified in the end application.
Depending on the installation situation, it may be necessary to install an
additional protective earthing conductor via the additional protective earth
connection point available on the device.
The protective earth connection point is located on the housing and has
a protective earth symbol and a bore hole.
4.2.2 Power supply connection, fuse protection

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 < 5 W.

Only universal (type B or B+) RCD protective devices are
permitted. Like frequency inverters, RCD protective devices
cannot provide personal safety while operating the device.
When switching on the power supply of the device, pulsed
charge currents from the capacitors in the integrated EMC filter
can lead to the RCD protective devices triggering without
delay. We recommend residual current devices with a trigger
threshold of 300 mA and delayed triggering (super-resistant,
characteristic K).
4.2.5 Leakage current
For asymmetrical power systems or if a phase fails, the
leakage current can increase to a multiple of the nominal value.
4.2.6 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 in terminal box
4.3.1 Preparing connection lines for the connection
Strip the cable just enough so that the screwed cable gland is tight and
the terminals are relieved of strain. Tightening torque, see chapter 3.1

4.6 Checking the connections
5. INTEGRATED PROTECTIVE FUNCTIONS
; Make sure that the power is off (all phases).
; Secure it from being switched on again.
The integrated protective functions cause the motor to switch off
automatically in case of faults described in the table.
; Check the correct fit of the connection lines.
Malfunctions
; Screw the terminal box cover closed again. Terminal box tightening
torque, see chapter 3.1 Product drawing.
; Route the connecting cables in the terminal box so that the terminal
box cover closes without resistance.
; Use all plug screws (the entire number). In doing so, insert the
screws manually to avoid damage to the thread.
; Make sure that the terminal box is correctly closed and sealed and
that all screws and screwed cable glands are properly tightened.
