→ Make sure the end of the cable is connected in a dry
environment.
The control voltage circuit is not electrically isolated. Only
connect the device to circuits that can be switched off with an
all-pole disconnection switch.
4.2.1 Requirements
; Check whether the data on the nameplate match the connection data.
; Before connecting the device, make sure the power supply matches
the device voltage.
; Only use cables designed for the current level indicated on the
nameplate.
For determining the cross-section, note the sizing criteria according
to EN 61800-5-1. The protective earth must have a cross-section
equal to or greater than that of the phase conductor.
We recommend the use of 105 °C cables. Ensure that the minimum
cable cross-section is at least

Fuse
●
The values are typically less than 250 mA.
●
At the same time, the effective power in this operating state
(operational readiness) is typically < 5 W.
4.2.4 Residual current circuit breaker (RCCB)
Only universal residual current devices (type B or B+) are
allowed. As with variable frequency drives, residual current
devices cannot provide personal safety while operating the
device.
When the device's power supply is switched on, pulsed
charging currents from the capacitors in the integrated EMC
filter can lead to the residual current devices tripping without
delay. We recommend the use of residual current circuit
breakers with a trip threshold of 300 mA and delayed tripping
(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 starting current (LRA) is
equal to or less than the nominal current (FLA).
