1.
Fusing in accordance with controller manual.
2.
It is not allowed to connect any other devices except the frequency inverter and the
power feedback unit behind the main magnetic switch.
Danger
If this is not observed, you take the risk that, in the case of switching off the
mains during feed back the power, the voltage in that sector may rise up to a
dangerous level. This may destroy the connected devices and perhaps also the
inverter and/or the power feedback unit. To avoid such situation, the power
feedback unit is equipped with an overvoltage switch off, but nevertheless this
hint should be observed!
3.
Fusing in accordance with power feedback unit manual. This may be left our, if at
position 1 semiconductor fuses or full range fuses are used and if after 1 the cross
section of the wires is not reduced.
4.
Cross section in accordance with the relevant VDE-rules.
5.
Fusing (230 V supply, <2A current input) in accordance with DIN VDE 0298 or
short circuit proof wiring.
6.
Design of the mains choke in accordance with controller manual (possibly not
applicable, if already installed inside the controller).
7.
At these terminals one ore more controllers (even with different power ratings)
may be attached, like it shown in figure
4.5.1. Even if several controllers are at-
tached, the wires have to be as
short and low impedance
as possible!
8.
The „ON“ or „RESET“ signal may be initiated via terminals 9 and 10 or 11 and 12:
Terminals 9 and 10:
potential free contact (short time contact)
Terminals 11 and 12:
positive pulse (12-24 V DC); practicable e.g. via PLC
(terminal 11 +, terminal 12 -).
