4. Installation.
4.1 Requirements.
The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230 V in and low-voltage installations.
As the power supply is designed for a continuous operation and is not equipped with a power-
switch, therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the
user should be informed how to disconnect the power supply unit from the mains supply (usually by assigning an
appropriate fuse in the fuse box). The electrical system shall be made in accordance with applicable standards
and regulations. The power supply should operate in a vertical position in order to provide free and
convectional air flow through ventilating holes of the casing.
The PSU is protected against access to the configuration menu through two-level passwords. If the
default settings should be changed, unlock access by entering the service password
– see Table 4 and
section 6.1.
4.2 Installation procedure.
CAUTION!
Before installation, cut off the voltage in the ~230 V power-supply circuit.
To switch off power use an external switch in which the distance between the contacts of all poles in the
disconnection state is not less than 3mm.
It is required to install an installation switch with a nominal current of min. 3 A in the power supply circuits
outside the power supply unit.
1. Mount the PSU in a selected location. It is particularly important to bolt the tamper grip to the mounting surface.
The grip is located in the central part of the enclosure (see fig. 3 [7]) and guarantees indication in case of any
attempts of detaching the device from the mounting surface. Proper installation is one of the requirements of the
EN 50131-6 standard.

2. Connect the power cables (~230 V) to L-N terminals of the PSU. Connect the ground wire to the terminal marked
by the earth symbol:
. Use a three-core cable (with a yellow and green protection wire) to make the connection.
Lead the cables to the appropriate terminals through the insulating bushing.
The shock protection circuit shall be performed with a particular care, i.e. the yellow and green wire
coat of the power cable shall stick to one side of the terminal - marked with the grounding symbol
on the PSU enclosure. Operation of the PSU without the properly made and fully operational
shock protection circuit is UNACCEPTABLE! It can cause a device failure or an electric shock
.
3.
Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
4.
If necessary, connect the device’s leads to the technical inputs and outputs:
- EPS FLT; technical output of AC power loss indication (alarm panel, controller, indicator, etc.)
- PSU FLT; technical output of the PSU failure.
