Operating instructions D3G318-AA37-11
Translation of the original operating instructions
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
4.2.1 Prerequisites
; Check whether the data on the type plate agree with the connection
data.
; Before connecting the device, ensure that the supply voltage matches
the operating voltage of the device.
; Only use cables designed for current according to the type plate.
For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor cross-
section.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
Earth wire contact resistance to EN 61800-5-1
Compliance with the impedance specifications to EN 61800-5-1 for the
protective earth circuit must be verified in the end application.
Depending on the installation situation, it may be necessary to install an
additional protective earthing conductor via the additional protective earth
connection point available on the device.
The protective earth connection point is located on the housing and has
a protective earth symbol and a bore hole.
4.2.2 Idle current
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and interference immunity), idle
currents in the mains cable can be measured even when the
motor is at a standstill and the mains voltage is switched on.
● The values lie in a range of typical < 250 mA.
● The effective power in this operating state (readiness for operation) is
simultaneously at typical < 4 W.
4.2.3 Residual current operated device
Only universal (type B or B+) RCD protective devices are
permitted. Like frequency inverters, RCD protective devices
cannot provide personal safety while operating the device.
When switching on the power supply of the device, pulsed
charge currents from the capacitors in the integrated EMC filter
can lead to the RCD protective devices triggering without
delay. We recommend residual current devices with a trigger
threshold of 300 mA and delayed triggering (super-resistant,
characteristic K).
4.2.4 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connection of the cables
External leads are brought out of device.
; First connect the "PE" (protective earth) connection.
● Connect the lines according to your application. When doing so,
observe chapter 4.4 Connection screen.
