These chargers are designed for mounting on a vertical
facia inside an enclosed control panel or housing.
Mounting orientation should be as shown above.
For safe heat dissipation, mount Sentinel in the orientation
shown, with a minimum air-gap clearance of 40mm
above/below and 25mm at the sides. Consideration must be
given to ventilation for proper heat dissipation.
For surface mounting, use the 2 centre slots (Ø 6mm)
or 4 corner slots (Ø 6mm). Ensure that the mounting
studs/bolts/nuts/screws adequately support the charger,
and are tightened sufficiently to not to become loose during
normal use, e.g. due to engine/equipment vibration.
Optional clip for DIN rail mounting (2 required for each
charger), part number 045-0001.

These chargers are designed for wall or frame mounting
in the orientation shown above, with enclosure air vents
uppermost. Adequate consideration should be given to
ventilation for proper heat dissipation.
Mounting is via the enclosure back-plate, using 4 holes
(Ø 6mm) on the upper and lower edges. 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).
Access to the electrical connection terminals is via
removable / hinged sections on the front facia. Remove the
6 x securing screws (marked F above), then remove or
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 (20mm/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 6 fixing screws.
