4.Safety Information
Batteries are potentially dangerous, and proper precautions must be observed in handling and
maintenance of batteries and monitoring systems. Maintenance shall be done only by personnel with
knowledge of batteries and the monitoring system and trained in the safety precautions involved. Properly
insulated tools and adequate personal protective equipment should be used when working with batteries.
The following precautions shall be observed when installing or servicing a battery:
a) Prohibit smoking and open flames in the immediate vicinity of the battery.
b) Avoid wearing metallic objects, such as jewelry.
c) Keep the top of the battery clear of tools and other foreign objects.
d) Provide unobstructed egress from the battery area.
e) Verify that the battery area and/or cabinet ventilation is operable.
f) Neutralize static buildup just before working on the battery by having personnel contact the nearest
effectively grounded surface.
It is recommended that a battery disconnection means be used to isolate a battery from the system. If a
battery disconnect is not provided, use extreme caution when removing the battery from the system. The
entire string voltage will appear across any two open points when the string is disconnected from the
system. Arcing will occur when the circuit is opened or closed if the charger/rectifier is not capable of
supporting the existing loads. This also will occur if the battery voltage and the system voltage are not
properly matched prior to the opening or closing action. For example, if the terminals are opened at the
individual cell level while the string is connected to a load, lethal voltages may be present across the open
circuit that is created by removing one side of the connection. Specialized training is required to perform
work on live battery systems
Electrical Hazard: Risk of electric shock: battery cabinets contain potentially lethal voltages!
A short-circuit can result in injury or death. Do not work alone.
Caution: Only qualified personnel, trained in battery operation and safety, may install the
harnesses. Keep unauthorized personnel away from the batteries.

5.1. Personal Protective Equipment
The following personal protective equipment shall be available to personnel who perform battery
maintenance work: goggles and face shields, acid-resistant gloves, protective aprons, portable or stationary
water facilities for rinsing eyes and skin in case of contact with electrolyte, class C fire extinguisher, acid or
alkaline neutralizer, and adequately insulated tools. Personnel shall wear protective equipment suitable for
the voltage of the battery when installing or servicing a battery.

5.2. Step 1: Determine battery numbers
Designate a battery number for each battery in the system. Before connecting the Battery Sensor BM3KRS to the batteries,
the batteries should be numbered and labeled correctly by using a label to paste on the surface of the battery where the
labels are easy to be seen. The first battery, or, battery NO.1 must be the first one on the string negative terminal, the NO.2
is the battery following the NO.1 battery, and so on. The last battery is the one attached closest to the string positive
terminal. The batteries should be numbered in accordance with this method.

5.3. Step 2: Install the Kelvin washers
Electrical Hazard: A short-circuit can result in injury or death. Do not work alone.
Perform a battery disconnection from the UPS system. Use Multimeter measures and confirms there’s no voltage
difference between battery and battery rack.
1) Remove the bolt from a battery;
2) Place the Kelvin Washer above the existing battery connection, behind the hex-head of the bolt.
3) Replace the bolt in the battery, and adjust its torque according to the specifications of the battery manufacturer.

5.4. Step 3: Connect the battery cables
1) Use an insulated pair of pliers (Important: Do not use your bare hands!) to slide the receptor end of each
cable over the tab portion on the washers that you installed on the positive and negative terminals of each
battery.
2) Remove the backing from the adhesive patches on the temperature sensor then position and mount it onto the
top or side of the battery block (Important: Make sure the surface is clean!).
