1. Technical description.
1.1. General description.
The LB5 (AWZ534) fuse block is used for power distribution in a low-voltage systems (power distribution). It
has the IN input for power connection, i.e. 10V-30V/DC or 10V-24V/AC (e.g. buffer power-supply, transformer, etc.).
The B5 module features five independently protected AUX1...AUX5 power outputs. An AUX output has short-circuit
protection (SCP) as a fuse (F 0,5A or F 1,0A) and surge protection - varistors. Any output state is indicated by five 1... 5
ED’s. A fuse failure is indicated by a proper ED switching-off, i.e. 1 for AUX1 etc. Moreover, if a failure occurs, the AW
output ( state) and the ED AW are activated. The AW output can be used for remote control of the B5 state, e.g.
translocated optical signalling.

2. Installation.
2.1 Requirements.
The B5 module shall be mounted by the qualified installer having appropriate (required and necessary for a
given country) permissions and qualifications for connecting (operating) low-voltage installations. The unit shall be
mounted in closed rooms, according to the environment class II, of the normal air humidity (RH=90% max. without
condensation) and the temperature within the range from -10°C to +40°C. The module shall be connected only to power
sources having galvanic (transformer) separation from the network supply.
The B5 shall be mounted in a metal casing (a cubicle, a terminal device) and in order to fulfill VD and EMC
requirements the rules for power-supply, encasing and shielding shall be observed according to application.
Before installation is started, the power balance shall be performed. During the normal and failure
operation, the sum of currents (power) collected by receivers from AUX outputs shall not exceed
performance of the power source connected to the IN input.
It is acceptable to change values of fuses to other than original, if the input/output balance and
safety standards (for cabling and the type of receivers) are maintained, and the maximum current of a
single output (2A / Σ5A @5xAUX) is not exceeded.
2.2 Installation procedure.
1. Install the B5 module on the mounting pins.
2. Supply power voltage to +IN, -IN terminals maintaining polarization for DC voltage.
3. Connect receivers to +AUX1-...+AUX5- terminals maintaining polarization for DC voltage.
4. Connect the failure signal, AW output (according to purpose of application) to the signalling device ( ED, transmitter
input, central input, indicator etc.).
5. After tests and operation control are performed, the casing (cubicle) shall be closed etc.
2.3 Procedure in case of short-circuit (SCP activation) of the LB5 output.
The AUX1÷AUX5 outputs of the B5 are short-circuit protected by fuses (fuse-elements). In case of damage, a
fuse shall be replaced for a proper one (the same as original or according to the standards and the balance).
