BF362-5 is a boxed Mains to regulated DC power supply providing 5 A @ 24 Vdc. Combining the functions of a power
supply unit, battery charging unit and battery monitoring unit, it is fully compliant with the current edition of
EN 54-4:1997 + A1:2003 + A2:2007.
INSTALLATION
Location
The power supply must be sited indoors on a dry, flat surface in an area that is well ventilated. Ideally the panel
indicators should be at eye level and the ambient light level should allow the status of the indicators to be clearly seen.
Mounting
Using the five mounting holes provided, mount the metal base securely onto a wall. Assess the condition and
construction of the wall and use suitable screw fixings. The mounting holes are suitable for use with No.8-10 or
4-5 mm countersunk screws. Any dust or swarf created during the mounting process must be kept out of the enclosure
and care must be taken not to damage any wiring or components.
Wiring and Cable Entry
All wiring should be installed in accordance with the current edition of the IEE Wiring Regs
(BS 7671), or the relevant national standards. The requirement for the Mains supply to the
panel is fixed wiring, using 3-core cable (no less than 1 mm
2
and no greater than 2.5 mm
2
),
or a suitable three conductor system fed from an isolating switched spur fused at 3 A.
In order to maintain cable segregation the incoming Mains cable should be fed into the
panel via the top centre knockouts (provided on the metal base). Knockouts should be
removed with a sharp, light tap using a flat 6 mm broadsided screwdriver, as shown in the
diagram (see right). Always ensure that if a knockout is removed, the hole is filled with a
good quality 20 mm cable gland. Any unused knockouts must be securely blanked off.
WARNING: DO NOT ATTEMPT TO CONNECT THE MAINS SUPPLY TO THE POWER
SUPPLY PCB UNLESS ALL COMPONENTS ARE SECURELY INSTALLED IN THE ENCLOSURE.
Terminate the Mains cable at the Power Supply connector block CONN1 (see Figure 1 below).
