Translation of the original operating instructions
NOTE
Device malfunctions possible
Route the device's control lines separately from the supply line.
→ 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 information on the nameplate matches 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.

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.
●
The values are typically in the range < 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)
If the use of a residual current device (RCD) is required in your
installation, only AC/DC-sensitive residual current devices
(type B 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).
4.2.5 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 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 4.5 Connection diagram.
