Translation of the original operating instructions
4.2.3 Residual current circuit breaker (RCCB)
Only pulse-current sensitive and/or universal residual current
devices (type A or B) are permitted. 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).
4.2.4 Locked-rotor protection
Due to the locked-rotor protection, the starting current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connecting the cables
The device has external leads.
;
First connect the "PE" (protective earth).
●
Connect the cables according to your application. When doing so,
observe Chapter 4.4 Connection diagram.
4.3.1 Cable routing
Water must be prevented from reaching the cable exit along the cable.
Fans installed lying flat
