Operating instructions
K3G225-RE07-01
Translation of the original operating instructions
Protective earth contact resistance according to EN 60335
Compliance with the resistance specifications according to EN 60335 for
the protective earth connection circuit must be verified in the end
application. Depending on the installation situation, it may be necessary
to connect an additional protective earth conductor by way of the extra
protective earth terminal provided on the device.
4.2.2 Reactive currents
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and immunity to interference),
reactive currents can be measured in the supply line even
when the motor is at a standstill and the line voltage is switched
on.
●
The values are typically in the range < 50 mA
●
At the same time, the effective power in this operating state
(operational readiness) is typically < 2 W.
4.2.3 Residual current circuit breaker (RCCB)
If the use of a residual current device (RCD) is required in your
installation, only pulse-current sensitive and/or AC/DC-
sensitive residual current devices (type A or B) are
permissible. As with variable frequency drives, residual current
devices cannot provide personal safety while operating the
device. When the device power supply is switched on, pulsed
charging currents from the capacitors in the integrated EMC
filter can lead to the instant tripping of residual current devices.
We recommend the use of residual current circuit breakers
(RCCB) 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.
