This manual contains important safety and operating instructions for models SUL100, SUL120, ESUL100 and ESUL120.
Do not expose charger to rain or snow
Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric
shock, or injury to persons.
Do not operate charger if it has received a sharp blow, been dropped, otherwise damaged in any way; return to suppli-
er.
Do not disassemble charger, return to supplier when service or repair is required. Incorrect reassembly may result in a
risk of electric shock or fire.
WARNING - RISK OF EXPLOSIVE GASES
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL BATTERY OPERATION.
To reduce the risk of battery explosion, follow these instructions and those published by battery manufacturers and man-
ufacturer of any equipment you intend to use in vicinity of the battery. Review cautionary marking on these products and
on any attached equipment.
PERSONAL PRECAUTIONS
(i) Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid
battery.
(ii) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
(iii) Wear complete eye protection and clothing protection. Avoid touching eyes while working near batteries.
(iv) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes, immediately flood
eyes with running cold water for at least 10 minutes and get medical attention immediately.
(v) NEVER smoke or allow a spark or flame in vicinity of battery.
(vi) Be extra cautious to reduce risk of dropping a metal tool onto battery. It may spark or short-circuit the battery or other
electrical part that may cause explosion.
(vii) Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid bat-
tery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a
severe burn.
(viii) Use charger only for charging batteries as stated on the charger. Do not use battery charger for charging dry-cell
batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and
damage to property.
(ix) NEVER CHARGE A FROZEN BATTERY
PRIOR TO INSTALLATION / COMMISSIONING
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge exces-
sive gas from cells. Do not overfill. For a battery without cell caps, carefully follow manufacturer’s recharging instructions.
Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and rec-
ommended rates of charge.
Determine voltage of battery by referring to engine manual and ensure matches charger’s output voltage.
CHARGER LOCATION AND CONNECTION
Never place charger directly above battery being charged, gases from battery will corrode and damage charger.
Never allow battery acid to drip on charger when reading specific gravity or filling battery.
Do not operate charger in a closed-in area or restrict ventilation in any way.
The battery charger should be connected to a grounded, metal, permanent wiring system; or an equipment-grounding
conductor should be run with circuit conductors not connected to equipment-grounding terminal on battery charger.
Connections to battery charger should comply with all local codes and ordinances.
SUL100 & SUL120 - These battery chargers should be installed so that they are not likely to be contacted by people.
ESUL100 & ESUL120 - The AC wiring should be independent of the DC and alarm wiring. Use AWG#12 or larger wre
for DC (charger to battery)leads. Use AWG#14 or larger for input and ground connections.
For safe and correct use of the unit follow the following steps, should you have any problems and the unit does not function as
expected consult our troubleshooting guide at the end of these instructions.
Visually inspect unit for any signs of damage, caused by transport or storage
Mount charger as outlined above, paying attention to ambient temperature
Ensure mains supply is isolated and connect observing the correct rated input voltage
Ensure unit is earthed at the marked earth stud
Check batteries in accordance with manufacturer guidelines
Check charger is correct for battery type and voltage
Connect unit to batteries, observing correct polarity and ensuring a secure and tight connection
Switch on unit at mains supply
