Current Limiting
The Sentry Battery Charger is current limited and will
only output the rated current of the charger (see chart
below)

SENTRY CURRENT RATINGS
Battery Charged Condition
When charged the battery will only accept a charge to
replace the losses within the battery (approx. 1mA per AH of
battery). If there is a standing load (i.e. the panel controller
etc) the charger will output the standing load plus the losses
to the battery i.e. if a standing load of 1A is present with
50AH Vented Lead Acid batteries then charger will supply
1.05 amps.
A charged battery with open circuit terminals (i.e. no load
connected) will always be higher than nominal battery volt-
age (i.e. 12.6 on a 12V lead acid battery)

IMPORTANT ASSEMBLY INSTRUCTIONS -
SAVE THESE INSTRUCTIONS
OPEN FRAME MODELS -
SUL100 & SUL120
The charger must be mounted as shown in Figure 2a.
Four screws should be used to mount charger to panel. Ensure screws
are tightened firmly as as not to become loose during normal use on
engine.
Adequate consideration should be given to ventilation for proper heat
dissipation.
WALL MOUNTED ENCLOSURE MODELS -
ESUL100 & ESUL120
The charger must be mounted as shown in Figure 2b.
The lower face is removed by unscrewing the four fixing screws. The
face is removed by sliding the face backward, thereby releasing the
“feet” from their fixing holes.
Cable entry is via knock-outs on the side of the unit, these must be
carefully removed from the enclosure sides.
A suitable cable-gland (20mm/0.8” DIA) should be used to prevent
damage to cables and stop unwanted entry into inner part of charger.
See “Electrical Connection” for details of terminal connections.
The lower face should be firmly screwed to the charger before use.
Four screws should be used to mount charger to panel. Ensure screws
are tightened firmly as as not to become loose during normal use on
engine.
Adequate consideration should be given to ventilation for proper heat
dissipation.

CAUTION:
When handling chargers, care should be taken not to place excessive strain on either the protective alu-
minium back plate, PCB, transformer or connecting wires. Unit should be handled by aluminium chassis (open frame
models) or steel enclosure (enclosed models).
