Legend for figure 5.6.1 (REVCON
RFE B2/D2)
1.
Fusing in accordance with controller manual.
2.
It is not allowed to connect any other devices except the frequency inverter and the
power feed/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 feed/feedback unit. To avoid
such situation, the power feed/feedback unit is equipped with an overvoltage switch off, but nev-
ertheless this hint should be observed!
3.
Fusing (230 V supply, <2A current input) in accordance with DIN VDE 0298 or short
circuit proof wiring.
4.
RFI-filter (optional): Cross section in accordance with the relevant VDE-rules.
5.
At these terminals one or more controllers (even with different power ratings) may be
attached, like it shown in figure
4.5.1. Even if several controllers are attached, the
wires have to be as
short and low impedance
as possible!
6.
Optional: The error relay of the feed/feedback unit must be wired (directly or indi-
rectly via a PLC) with the pulse- stop of the controller, to avoid operation of the drive
during the capacitor precharge or during an over temperature of the heatsink.
Danger!
If this is not observed, components of the feed/feedback unit will be overloaded and possibly
damaged.
7.
The possibility of an „ON“ or „RESET“ signal takes place via terminals or 11 and 12:
Terminals 11 and 12: Positive pulse (12-24 V DC); practicable e.g. via PLC (termi-
nal 11 +, terminal 12 -).
