Operating Instructions and Safety Precautions for the EHF Series Charger
Safety
Only a t rained person should operate this equipment. The input
and output voltages used with this equipment may be high enough
to endanger life, so insulated, shrouded connectors must be fitted.
Please read this manual completely and convey instructions to all
personnel
concerned
. Keep the manual in a safe and convenient
place.
It is advisable to thoroughly read the information on battery safety
supplied with the battery, prior to charging.
Towards the end of charge, lead acid batteries give off hydrogen
gas, which is explosive if in sufficient concentration, therefore
avoid flames and sparks. Appropriate measures must be taken to
ensure adequate ventilation.
Incorrect use of a charger or maladjustment of its controls can
damage a battery. The equipment has been factory set and does
not require user adjustment.
This product has been designed, manufactured and certified to be
in conformance with UL Standards. Testing has ensured that the
battery and c harger combination conform as a system for use in
Light and Heavy Industrial environments for each respective
product variant. The following notes are for the guidance of the
person installing and using the product.
The charger must be i solated from the input supply and t he
battery, before any of the panels are removed. It is strongly
recommended that a Safety Warning Notice is placed at the input
supply isolator, to warn against inadvertent reconnection of the
mains supply and the isolator is locked in the off position.
DANGER - Risk of electric shock. Do not touch un-insulated
portion of output connector or un-insulated battery terminal.
Installation
Installation must only be carried out by suitably qualified personnel
and in accordance with current local and national wiring
regulations.
The unit should be positioned using lifting equipment, placed under
the base.
Battery leads should not be altered without prior consultation with
service personnel.
The charger should be sited in a cool, dry, well-ventilated location
away from corrosive fumes and humid atmospheres. Ambient
temperature range must be maintained between 32°F - 95°F.
The charger must
have a minimum clearance overhead of eight
inches (8”), ensuring ventilation is not obstructed at the rear intake
and the front exhaust vents.
The charger is for inside use only.
Before installation, check that:
•
The charger has not sustained any transit damage.
•
The rating is suitable for the intended input supply and ‘lead
acid’ battery to be charged.
•
The connector polarity is correct and matches the polarity of
the battery connector.
Input supply
A hand operated lockable isolator should be used in the
installation, to enable the charger to be disconnected from the
supply, for maintenance or repair work. The charger does not
exhibit high in-rush current, therefore type B or C circuit breakers
can be used.
CAUTION - To reduce the risk of fire, use only on circuits provided
with branch circuit protection consistent with the current indicated
on the rating label and in accordance with the National Electrical
Code, ANSI/NFPA 70 or equivalent.
The circuit breakers rating should be bas ed on the chargers
maximum input current, as stated on the rating label.
Careful consideration must be taken when connecting this charger
to a generator. The generator must be capable of at least four
times the input power requirements of the charger, failure to do so
can result in damage to the charger. The generator should have
load step immunity to prevent undershoot and overshoot with
typical loads. Typically the generator control bandwidth should be
less than 7Hz with good gain and phase margins.

Operation
Before connecting the battery, check that the battery voltage
corresponds to the voltage indicated inside the battery
symbol on the LCD Display. The charger should be
permanently connected to the mains supply.
Standby
With the input supply connected and no battery, the charger will
e
nter the standby mode. During this mode the charge status
indicator will show indication 6 and the LCD display will show the
following:
