Installation and electrical connection
of the system
3.1
General, highly important information
Tighten all screws and connections as otherwise the warranty will be
rendered void.
The device must be installed and operated in accordance with the applicable
VDE regulations (in particular VDE 0100) and the energy supplier regulations.
Connection cross-sections and fuse protection table: see attachment
3.2
Current transformer connection and measuring voltage
If possible, mount the transformer in the phase that corresponds to L1 of the
compensation system (determine by means of voltage measurement).
All capacitor and consumer currents must be determined. In case of an unbal-
anced phase load (in small operations), install the transformer in the phase with
the highest load.
P1 (K) to energy supply (indicated on the transformer).
P2 (L) to load outputs
S1 (k) with terminal k (controller terminal 20) and
S2 (l) with terminal l (controller terminal 21) should be connected in the com-
pensation system (use a two-color cable!).
Line cross section: up to 3 m =1.5 mm², up to 6 m =2.5 mm². For greater distanc-
es, we recommend using a 1 A transformer. The controller is designed for the
connection of 5 A and 1 A transformers; switching is set in the confi guration.
If using existing transformers, the current paths always need to be connected in
series. The secondary transformer current needs to be at least 15 mA.
For lower currents, no capacitors will be connected (display shows “missing
current”). Measuring voltage connection according to the connection diagram.
