i Pay attention to the necessary cable cross-section of the common power cable.
i If multiple power boosters are used, add up the minimum loads of all the separate devices.
i In the case of lighting systems with an output of over 3500 W/VA, the installation must be
distributed across two miniature circuit breakers with the same conductor.
o Connect the power booster according to the connection diagram, connection diagram with
RMD dimmer (figure 2), connection diagram with FM dimmer (figure 3) or connection
diagram with multiple power boosters (figure 4).
o If multiple circuit breakers supply dangerous voltages to the device or load, couple the
circuit breakers to ensure tripping.
Calculation example for the number of power boosters required:
P
L
Load to be dimmed, e.g. 2200 W
P
D
Max. dimmer load, e.g. 500 W
P
LZ
Max. universal power extension load, e.g. B.
500 W
P
LZG
Power that the power boosters have to provide
n Number of power boosters required
Calculation of the load to be covered by power boosters:
P
L
- P
D
= P
LZG
P
LZG
= 2200 W - 500 W = 1700 W
Number of power power boosters:

PLZ
= n
n = 1700 / 500 = 3.4
4 power boosters are required for the loads assumed in the example.
