CAUTION
Observe the supply voltage!
⇒
The REFU
drive 500
units are designed and manu-
factured for various line supply voltages! Thus, line
supply voltages are not specified in the drawings and
tables for the terminal strips.
⇒
When connecting-up the equipment, please observe
the line supply voltage specified on the rating plate
and in the Technical Data.
Information regarding protective grounding
As a result of the equipment discharge currents (>3.5mA)
through the protective conductor (PE), according to DIN
VDE0160, the cross-section of the protective conductor to the
cabinet must be at least 10mm
2
Cu, or a second protective
conductor must be connected in parallel. (VDE 0160, Section
6.5.2). The equipment discharge currents can be up to 100
mA.
For higher ratings, the minimum cross-section of the protective
conductor must have the appropriate relationship to the cross-
section of the phase conductor. Refer to DIN 57100 Part 540 /
VDE 0100 Part 540 Table 2. The line-side circuit of the drive
converter corresponds to circuit 7 (DIN VDE 0160-5.5.3.4.2
Fig. 8).
In this case, it is not permissible to use e.l.c.b.’s as protective
device.
