4. Installation.
4.1 Requirements.
Enclosure should be mounted by a qualified installer, holding relevant permits and licenses (applicable and required fora given
country) for 230 V and low-voltage installations. Device shall be mounted in confined spaces with normal air humidity
(RH=90% max. without condensation) and temperature from -10°C to +40°C. Enclosure shall work in a vertical position that
guarantees sufficient convectional air-flow through ventilating holes of enclosure.
4.2 Installation procedure
Before installation, cut off voltage in the 230 V power-supply circuit.
To switch power off, use an external switch, in which the distance between the contacts of all
poles in disconnection state is not less than 3mm.
1. Mount PSU in a selected location and connect wires.
2. Connect power cables (230 V) to L-N clips of PSU.
Shock protection circuit shall be performed with a particular care, i.e. yellow and green wire
coat of power cable shall stick of terminal - marked
with ‘
‘ symbol on PSU enclosure.
Operation of PSU without properly made and fully operational shock protection circuit is
UNACCEPTABLE! It can cause a device failure or an electric shock.
3. Connect ground wire to terminal marked with
symbol (power supply module connector). Use a three-core cable
(with a yellow and green
protection wire) to make connection. Lead the cables to the appropriate clips through
insulating bushing of the connection board
4. Screw brackets to devices and install them inside enclosure. Remember to place devices starting from rear of enclosure.
5. Make necessary electrical connections.
5. Connect the power (230 V).
6. After installing and checking proper working, enclosure can be closed.
