AccuMate PRO
(GB) Instructions for Use
IMPORTANT : Read completely before charging.
Automatic charger for all lead/acid batteries of voltage type matching the rated output voltage stated on the
charger. Not for charging dry cell or NiCad batteries. Input supply 220-240V~. Minimum rated capacity of batte-
ry to be charged : at 12V - 4A, 10Ah;. At 12V - 6A, 15Ah; at 12V - 7A, 17Ah; at 24V - 3,5A, 8Ah.
IMPORTANT ! If the charger has a charging output selector switch to select for 12V batteries (which have
6 cells) or 24V batteries (which have 12 cells), IT IS ESSENTIAL TO ENSURE THAT THE SELECTOR SWITCH IS
CORRECTLY POSITIONED ACCORDING TO THE VOLTAGE OF THE BATTERY TO BE CHARGED BEFORE THE CHARGER
IS CONNECTED TO IT.
If not sure, contact the battery supplier for advice before connecting the charger.
WARNING ! Connecting a battery without ensuring that the charging output selection is appropriate to the
nominal battery voltage may cause a hazard resulting in the production and accumulation of dangerous
explosive gases as well as the overheating and potential destruction or even the explosion of the battery.
THIS COULD RESULT IN SERIOUS PERSONAL INJURY OR EVEN DEATH.
WARNING ! Batteries emit EXPLOSIVE GASES - prevent flame or sparks near batteries.
SAFETY : Ensure adequate ventilat i o n . Disconnect AC power supply before making or breaking DC/ bat t e ry
connections.Battery acid is highly corrosive. Wear protective clothing and eye shielding and avoid contact. In case of
accidental contact wash immediately with soap and water. Check that the battery posts are not loose; if so, have the
battery professionally assessed. If the battery posts are corroded, clean with a copper wire brush; if greasy or dirty,
clean with a rag damped in detergent and dry. Before charging batteries provided with filler caps check that the
electrolyte level is correct,and top up with distilled water if necessar y. Do not use the charger unless all input and out-
put leads and connectors are in good,undamaged condition.
Protect your charger and it's leads, connectors, fuse holders, fuses and terminations from contamination by
acids and fluids,from exposure to damp and humidity, and from physical and accidental damage. Any damage
to the unit,it's leads or accessory parts resulting from such contamination, exposure or damage,whether during
use or in storage,is NOT covered by warranty.
CONNECTIONS : This charger is delivered with two detachable battery connection lead sets.These sets terminate
at one end with the male element of a special 2-pin connector to insert in the female element which terminates the main
charger output cable.At the other end, one connection set has «crocodile» clips for quick connection to the battery, the
other set has eyelet lugs for permanent attachment to the battery posts.
If intending to charge using the battery clips,first disconnect and remove the battery from the vehicle and place in a well-
ventilated area. To use the eyelet connection set,fix the eyelets firmly to the battery posts either with galvanised gutter
bolts and nuts or in the case of solid posts by galvanised self-tapping screws engaging in suitable holes pre-drilled in the
posts.Make sure that the eyelet on the lead with the in-line fuse holder is fixed to the positive pole (marked Pos or P or
+ and often red) and the other eyelet to the negative pole (Neg or N or - and often black).Ensure that the polarised 2-pin
connector is situated away from the battery and restrained so as not to come into contact with any moving part of the
vehicle.Prevent ingress of grime and dirt to the 2-pin connector.
If in any doubt concer ning any of the above instructions, consult a professional ser vice agent for assistance.
Other specialised connection accessories are available as options.Ask your dealer for details.
TEMPERATURE : This charger monitors both it's own internal temperature, which it limits automatically by current
r e g u l at i o n , and (except model AMPRO/A12-4) the surrounding ambient temperat u r e , according to which it varies it's
charging output voltage parameters. Some models have a built-in cooling fan. Should the internal temperature rise
excessively in spite of this,due to restricted ventilation or extreme ambient conditions,the charging output will be reduced
automatically until the internal temperature has stabilised at a safe level.Should the fan be jammed or out of order, the
charger will be disabled and should be sent to a service agent for checking and repair. Models equipped with plug-
in temperature sensor : the charging output voltage parameters are increased or decreased by 4mV/°C /cell according to
decreases or increases respectively in the monitored ambient temperature,the nominal voltage parameters for each stage
of charging being set at a 20°C (68°F) datum.On removal of the ambient temperature sensor which is plugged in at the
rear of the charger, the voltage parameters will revert to their default settings as enumerated in the «Charging Procedure»
text below. For more exacting applications,the standard plug-in sensor can be removed and replaced by an optional 2m
long probe whose NTC thermistor tip when taped to the battery casing affords precise monitoring of the actual battery
temperature for optimum voltage management.Order reference AMPROTPRO2.
