Art. No. ULZ 1215 REG
Operating instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
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.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
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 according to EN 61558-2-6 may be used.
A minimum power of 10 kVA is required for operation on isolating transformer networks.
Otherwise it is not ensured that the dimmer will correctly recognise the dimming
principle suitable for the load. Device can be damaged.
These instructions are an integral part of the product, and must remain with the end
customer.

- Suitable for mixed operation up to the specified output (see section Technical data)
- Installation in distribution boxes on DIN rail according to EN 60715
i Lighting systems with an power of more than 1000 W/VA are professional applications.
i No mixed operation of Tronic and inductive transformers.
i Operation with HV LED lamps is not possible.
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 boosters.
- Power is supplied to the connected loads via a common power cable
- Operation using upstream dimmer
- Electronic over-temperature protection
i Flickering of the connected lamps due to undershoot of the specified minimum load or
through centralised pulses from the power stations. This does not represent any defect in
the device.
i Brightness differences between the lighting on a dimmer without powerpower booster and
a dimmer with power booster are possible.
4 Information for electrically skilled persons
4.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Fitting and connecting the power booster
i To prevent overheating, maintain a distance of 1 module when operating multiple dimmers
or power units within the same control cabinet.
i The terminals must be at the top.
o Snap power booster onto DIN rail.
CAUTION!
Destruction of the devices when connected to the wrong outer conductor.
The dimmer and power boosters will be destroyed.
Connect all devices to the same outer conductor.

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.

Figure 6: Reference list KNX dimmer
The icons used to label the dimmer load shows the load type that can be connected
to a dimmer and the electric behaviour of a load:
R = ohmic, L = inductive, C = capacitive
5.2 Troubleshooting
System has switched off.
Cause 1: short-circuit protection has tripped. The power booster behaves like the upstream
dimmer.
Eliminate short-circuit.
i 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.
Switch circuit breakers and system on again.
i 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.
