yi6503 revision A 2017-02-24 p2/8
Important Safety Information
– Read and Save These Instructions
This manual contains important safety and operating instructions for all SNTL150, SNTLUL150, ESNTL150 & ESNTLUL150 models.
Do not expose the battery charger to rain, snow or wet environments.
The use of any attachment not recommended or sold by the battery charger manufacturer may result in risk of fire, electric
shock or injury to persons.
Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged in any way: return to supplier.
Do not disassemble the charger: return to supplier when service or repair is required. Incorrect re-assembly may result in a risk
of electric shock, fire or faulty operation.
WARNING
– RISK OF EXPLOSIVE GASES
WORKING IN THE 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 the
manufacturer of any equipment you intend to use in the vicinity of the battery. Review cautionary marking on these products and
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, eyes or clothing.
(iii) Wear complete eye protection and clothing protection. Avoid touching eyes whilst 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 immediate medical attention.
(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 on to the 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 batteries. High power
batteries can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burns.
(viii) Use the charger only for charging battery types as stated on the charger. Do not use the 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 into contact with eyes.
Add distilled water in each cell until the battery acid reaches a level specified by battery manufacturer. This helps purge
excessive gas from the cell. Do not overfill. For a battery without cell caps, carefully fo
llow manufacturer’s recharging
instructions.
Study all battery manufacturer’s specific precautions, such as removing or not removing cell caps while charging and
recommended rates of charge.
Determine the voltage of battery by referring to engine manual an
d ensure this matches the charger’s output voltage.
CHARGER LOCATION AND CONNECTION
Never place the charger directly above battery being charged: gases from the battery will corrode and damage the charger.
Never allow battery acid to drip on to the charger when reading specific gravity or filling battery.
Do not operate the 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 the battery charger.
Connections to the battery charger should comply with all local codes and ordinances.
Open frame SNTL models
– these chargers should be installed so that they are not likely to be contacted by people.
Wiring for the AC supply input, DC charge output and DC control (e.g. alarm output) circuits must be physically separate, e.g.
using separate wire harnesses and cable gland access. For AC input and ground leads, use 1mm²/17 AWG or larger wire
conductors rated to 90°C/194°F. For DC (charger to battery) leads, use 2.5mm²/13 AWG or larger wire on standard charger
models, and 4mm²/11 AWG or larger wire on NFPA models.
For safe and correct use of the charger, follow the following steps. Should you have any problems or 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 the charger as outlined above, paying attention to ambient temperature.
Ensure the mains AC supply is isolated, and ensure the correct rated input voltage before connection.
Ensure the charger is earthed at the marked earth terminal/stud.
Check
batteries in accordance with the manufacturer’s guidelines.
Check that the charger is correct for battery type and voltage.
Connect the charger to the batteries, observing correct polarity and ensuring a secure and tight connection.
Switch on the charger at the mains AC power supply.
