Operating instructions
A3G990-AZ02-01
NOTE
Device malfunctions possible
Route the device's control lines separately from the supply line.
4.2.3 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.
→ Maintain the greatest possible clearance.
Recommendation: clearance > 10 cm (separate cable
routing)
NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
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
AWG 26 / 0.13 mm².
Ground conductor contact resistance according to EN 61800-5-1
Compliance with the impedance specifications according to EN 61800-51 for the protective earth connection circuit must be verified in the end
application.
Depending on the circumstances of installation, it may be necessary to
connect an additional protective earth conductor to the extra protective
earth terminal on the device.
The protective earth terminal is on the housing and has a ground
conductor symbol and a bore hole.

●
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).
4.3 Connection in terminal box
4.3.1 Preparing cables for connection
Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.
NOTE
Tightness and strain relief are dependent on the cable
used.
→ This must be checked by the user.
