1.7 Installation, connections and starting.
The power supplies are intended for installation as part of an installation by qualified personnel. The battery should not
be present in the power supply during installation. Removal of the power supply module itself is not required. The PSU casing is
prepared for running the power supply and load cables through the rear casing. The dedicated holes are shown in the drawing
in pt. 1.2.
Before assembly, on the selected surface (e.g. wall with wall plugs), prepare 4 holes with a spacing of 350 × 275mm. In the
two upper holes, appropriate screws should be screwed in (maximum head diameter 8mm), on which the power supply cabi-
net should be hung. Inserting the two bottom screws locks the cabinet. All screws can be tightened in this state.
The power supply must be connected to a fixed installation using a protective conductor and taking into account the L, N
and PE markings. It is recommended to equip the installation with an overvoltage protection system. It is required to install in
the supply circuits, apart from the power supply, an installation switch with a nominal current of at least 3A. This switch is only
used to protect the mains supply cables against short
-
circuit and can be used for service and testing purposes
-
checking that
the output voltage is maintained in the event of a mains power failure.
The power supply's transformer is equipped with its own fuse in the mains supply circuit. This fuse cannot be replaced, be-
cause its blown is a sign of serious damage.
The power supply is designed to work with a 12V battery, the so
-
called maintenance
-
free, which should be placed in the
cabinet after mechanical and electrical assembly is completed. Pay particular attention to the polarity of the connection betwe-
en the PSU module and the battery pack.
If the connection is incorrect, the battery circuit fuse will be damaged.
After making all the necessary connections (mains power supply, battery pack and possible loads
-
their connection is not
necessary to check the operation of the power supply), the ability to maintain the output voltage can be checked. To do this,
turn off the mains supply with a switch located in the mains supply line, apart from the power supply itself, and check the pre-
sence of voltage at the outputs of the power supply, which is indicated by LED diodes located on its printed circuit board. You
can also use an ohmmeter to check the position of the MAIN FLT relay. The status of signaling is presented in the table below.
*) The relay is ON when it has moved in relation to the drawing describing this output
(the drawing shows the system of contacts in the OFF state of the relay).
