IMPORTANT SAFETY INSTRUCTIONS
This manual contains important instructions for Models; SB3048L, SB3048DL, SB50RD25
SAVE THESE INSTRUCTIONS
1. Refer installation and servicing to qualified service personnel. High voltage is present inside unit. Incorrect installation or use may result in risk of electric shock
or fire. No user serviceable parts in this unit.
2. To reduce the risk of electric shock, fire or personal injury, the following symbols are placed throughout this manual to indicate dangerous conditions, or
important safety or operational instructions.
WARNING CAUTION IMPORTANT
)
Indicates dangerous conditions or electric
shock potential. Use extreme caution.
Indicates items critical to safe installation or
operation of the unit.
Follow these instructions closely for proper
operation of the unit
3. PERSONAL PRECAUTIONS
a) Working in the vicinity of lead-acid batteries is dangerous. Batteries produce explosive gasses during normal battery operation.
b) To reduce risk of battery explosion, follow these instructions and those published by battery manufacturer and manufacturer of any equipment you intend
to use in vicinity of battery.
c) Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery.
d) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
e) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
f) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at
least 10 minutes and get medical attention immediately.
g) NEVER SMOKE or allow a spark or flame in vicinity of battery.
h) Be extra cautious to reduce risk of dropping metal tool onto battery. It might spark or short circuit battery or other electrical part that may cause explosion.
i) Remove personal metal items such as rings, bracelets and watches when working with a lead-acid battery. 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.
j) Remove all sources of power, photovoltaic and battery before servicing or installing.
4. CHARGER LOCATION & INSTALLATION
a) This unit is designed to charge flooded or sealed type lead-acid chemistry batteries. Follow battery manufacturers charging recommendations when
considering this unit for use with other battery chemistry, i.e., NiCd.
b) This unit employs components that tend to produce arcs or sparks. NEVER install in battery compartment or in the presence of explosive gases.
c) This unit must be installed and wired in accordance with National Electrical Code, ANSI/NFPA 70.
d) Over current protection for the battery must be provided externally. To reduce the risk of fire, connect to a circuit provided with 40 amperes maximum
branch-circuit over current protection in accordance with National Electrical Code, ANSI/NFPA 70.
e) Insure that unit is properly configured for the battery being charged.
f)
Unit is not water tight. Do not expose to rain or snow.
g) Insure all terminating connections are clean and tight. Battery and PV compression terminals are to be tightened to 50 in-lb (5.6 nm). Shunt and battery
temperature sensor compression terminals are to be tightened to 2.1 in-lb (0.23 nm).
h) Charging system must be properly installed as described in these instructions prior to operation.
i)
Do not connect to a PV array capable of producing greater than 24 amps of short circuit current @ 25 °C STC
j) WARNING – This unit is not provided with a GFDI (ground-fault detector/interrupter) device and must be used with an external GFDI device as required
by Article 690 of National Electrical Code for the installation location.
5. PREPARING TO CHARGE
a) Never charge a frozen battery.
b) Be sure battery is mounted in a well ventilated compartment.
c) Add distilled water in each cell of a lead-acid battery until battery acid reaches level specified by battery manufacturer. This helps purge excessive gas
from the cells. Do not overfill. For batteries other than flooded lead-acid type, or sealed batteries without cell caps, carefully follow manufacturers
charging instructions.
