Operating instructions
1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
Danger of electric shock. Always disconnect before carrying out work on the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage. The load
is not electrically isolated from the mains even when the device is switched off.
A minimum power of 10 kVA is required for operation on isolating transformer networks. Other-
wise it is not ensured that the dimmer will correctly recognise the dimming principle suitable for
the load. Device can be damaged.
Fire hazard. For operation with inductive transformers, each transformer must be fused on the
primary side in accordance with the manufacturer's instructions. Only safety transformers ac-
cording to EN 61558-2-6 may be used.
These instructions are an integral part of the product, and must remain with the end customer.
2 Intended use
– Power enhancement for the dimmers contained in the reference list (see section Tech-
nical data)
– Mounting in a sub-distribution unit on DIN rail according to EN 60715
Lighting systems with an power of more than 1000 W/VA are professional applications.
3 Product characteristics
– Connection of several power boosters to a single dimmer
– The total power of the connected loads is divided between the dimmer and power boost-
ers.
– Power is supplied to the connected loads via a common power cable
– Operation using upstream dimmer
– Electronic over-temperature protection
Brightness differences between the lighting on a dimmer without power booster and a
dimmer with power booster are possible.

When operating multiple dimmers or power boosters in a sub-distribution, maintain a dis-
tance of 1 module, approx. 18 mm, between the devices in order to prevent overheating.
If multiple power boosters are used, add up the minimum loads of the individual power
boosters.
Pay attention to the necessary cable cross-section of the common power cable. The max-
imum connectable power is the sum of the individual loads of the dimmer and the connec-
ted power boosters.
Connect 600 Watt LED lamps or compact fluorescent lamps at most per 16ampere circuit
breaker.
When connecting transformers, observe the data of the transformer manufacturer.
Our dimmers and power boosters take into account the different electronic characteristics
of most LED maps found on the market. However, it cannot be guaranteed that in indi-
vidual cases the desired results may not be achieved.
￭ Observe the clampable conductor cross-sections of the connection terminals (Figure 3).
￭ Snap the power booster onto the DIN rail and connect according to the connection ex-
amples (dimmer with one power booster (Figure 1), dimmer with multiple power boosters
(Figure 2)).
Calculation example for the number of power boosters required
P

n Number of power boosters required
Calculation of the load to be covered by power boosters:

n = 680W / 420W = 1.6
2 power boosters are required for the loads assumed in the example.

￭ Disconnect the dimmer from the mains supply.

6 Troubleshooting
System has switched off.
Cause 1: short-circuit protection has tripped. The power booster behaves like the upstream dim-
mer.
Disconnect system from mains, switch off circuit breakers.
Eliminate short-circuit.
The short-circuit protection is not based on a conventional fuse. Thus the load circuit is
not interrupted electrically.
Cause 2: overheating protection has tripped.
Disconnect system from mains, switch off circuit breakers.
Let system cool down for approx. 15 minutes.
Check the installation situation.
Reduce the connected load.
LED load in leading edge phase control, check if operation is possible in trailing edge
phase control.
LED load, use another type of lamp.
Switch circuit breakers and system on again.
Load is initially distributed to the remaining devices. The further behaviour of the system
depends on the dimmer used and the number, utilisation and installation situation of the
devices.
7 Warranty
The warranty is provided in accordance with statutory requirements via the specialist trade.
