The
AWO 270
metal casings
compliant with EN50131 GRADE3
are designed as components (supplying) in
intruders alarms, access control systems, security systems etc. There are intended for installation:
control panel optional with supplementary modules
access control controllers with optional modules
radio or GSM transmitter with optional module PSU
other dedicated devices, components etc.
2. Installation:
The metal casing (+PCB) must be installed by a qualified installer, holding the relevant certificates, required and
necessary in the particular country for connecting (interfering with) the ~230 V systems and low-voltage installations.
Because the transformer is designed for the continuous operation and is not equipped with ON/OFF switch, the
power supply line should have the appropriate overload protection. The user should be informed how to disconnect the
unit from the mains (the most often by separate and mark the adequate fuse in the fuse box). The power supply
installation should be conform to the applicable standards and law.
The casing (+PCB) should be installed indoors, where the air humidity is normal (RH=90% max. without
condensation) and temperature in the range of -10°C to +40°C.
Caution! Prior to entering for installation it is necessary to make sure if the voltage
in the ~230 V circuit is disconnected.
All service works inside the housing must be carried out with ~230 V supply voltage
disconnected.
1. Mount the PCB (control panel, etc) with dedicated holes (use distance pins, bracket screw).
2. Install metal casing in dedicated place and bring in the connecting (~230 V) and signal conductors through cables
bushings.
Remarks:
supply circuit ~230 V should be carried out with three-core cable
(with yellow-green protective PE conductor).
3. Supply conductors ~230 V should be connected to
~230 V L-N
terminals of the transformers.
Protective conductor should be connected to the terminal marked with grounding symbol.
Caution! Operating the power supply without properly made and technically
operational electric shock protection circuit is IMPERMISSIBLE!
This creates hazard of equipment damage and risk of electric shock.
4. Connect the output of transformer to the terminals (~AC) on the PCB, using installed cables
Remarks:
connect required voltage U1 or U2 (secondary voltage) for the correct device.
5. If necessary, make other connections required for the correct type of system / device.
Remarks:
consistent with requirements and recommendation of the producer.
6.
Start the system (switch on ~230 V, battery), adjust or configure: according to procedure of the
producer’s system.
7. After installing and checking the proper operation of the system, close the casing.
