DIMENSIONS AND ASSEMBLY
CAUTION: When handling chargers, care should be taken not to place excessive weight or strain on either the
heatsink, circuit boards, transformer or connecting wires. The units should be handled by the transformer
frame (open frame models) or steel enclosure (enclosed models). Care should also be taken not to handle
static sensitive components on the circuit board.


These chargers are designed for mounting on a vertical
facia or plate inside a control panel or housing. For safe
heat dissipation, mount the product in the orientation
shown with a minimum air-gap clearance of 40mm
above/below and 25mm at sides. Consideration must
be given to ventilation for proper heat dissipation.

4 chassis slots (Ø 6mm) are provided for mounting.
Ensure that the mounting studs/bolts/nuts/screws
adequately support the charger weight, and are tightened
sufficiently to not to become loose during normal use
(e.g. due to engine/equipment vibration).


These chargers are designed for wall or frame mounting
in the orientation shown above, with enclosure air vents
uppermost. For safe heat dissipation, allow a minimum air-
gap clearance of 40mm above/below and 25mm at sides.
Adequate consideration should be given to ventilation for
proper heat dissipation.

Mounting is via the enclosure back-plate, using 2 slots
(Ø 6mm) on the back-plate lower edge and 2 holes
(Ø 6mm) on the upper edge. Ensure that the mounting
studs/bolts/nuts/screws adequately support the charger
weight, and are tightened sufficiently to not to work loose
during normal use (e.g. due to engine/equipment
vibration).

Access to the electrical connection terminals is via hinged
sections on the front facia. Remove the 4 x securing
screws (marked F above), and rotate the upper and lower
sections through 90 degrees.

Electrical cable entry is via knock-outs on either side of the
enclosure, which must be carefully removed from the
enclosure sides. A suitable cable-gland (20 mm /
0.8”
diam.) must be used to prevent damage to cables and
stop unwanted entry into inner part of charger.

Connect the charger wiring as detailed in the following
section, “Electrical connection”. When wiring is complete,
and before using the charger, re-secure the hinged
sections using the 4 fixing screws.
