VRLA battery user's manual

Battery posts, terminals and related accessories contain lead and lead com­pounds, and other chemicals known to the state of Californiato cause cancer and birth defects or other reproductive harm. Wash hands after handling.

 

Safety Precautions

Although all valve-regulated batteries have the elec­trolyte immobilized within the cell, the electrical hazard associated with batteries still exists. Work performed on these batteries should be done with the tools and the protective equipment listed below. Valve-regulated battery installations should be supervised by personnel familiar with batteries and battery safety precautions.

 

Protective Equipment
To assure safe battery handling, installation and maintenance, the following protective equipment should be available:

● Safety glasses or face shields
● Acid-resistant gloves
● Protective aprons
● Lifting devices
● Tools with insulated handles

 

Procedures


The following safety procedures should be followed during installation: (Always wear safety glasses or face shield.)

Adequately secure battery racks or cabinet enclosures to the floor.
Connect support structures to ground system in accordance with applicable codes.
Inspect all flooring and lifting equipment for functional adequacy. Specifically review floor loading capacity.
Prohibit smoking and open flames, and avoid arcing in the immediate vicinity of the battery.
Keep the top of the battery clear of all tools and other foreign objects.
Provide adequate ventilation and follow recommended charging voltages.
Avoid wearing metallic objects such as jewelry while working on the battery.
Never remove or tamper with the pressure relief valves.
These batteries are sealed and contain no free electrolyte. Under normal operating conditions they do not present any acid danger.
However, if the battery case or cover is damaged, acid could be present. Sulfuric acid is harmful to the skin and eyes. Flush affected area
with water immediately and consult a physician if splashed in the eyes.
Do not use C02 to extinguish battery fires. Use a halon-generated fire extinguisher system.

 

BatteryInstallation

 

The Spirit Series & Main Line series batteries are provided with inter-battery bus bars to connect batteries in series to create battery strings. One bus bar is provided with the accessory kit and comes complete with hard­ware to create various size strings of batteries as specified for the application (e.g., 24V or 48 V battery strings). When planning or installing the Spirit Series or Main Line Series battery, refer to Figure 3 to determine battery spacing. These two figures show the maximum and minimum spacing of the batteries when they are positioned end to end either short face to short face or long face to long face.

NOTE: Do not refer to these figures for help in connecting the batteries in strings. These figures are not intended to depict wiring options.

 

BatteryInstallation Procedure

Before proceeding with the installation of the battery, review or determine the arrangement of the batteries for the application.
The battery terminals are precoated with NO-OX-ID A® compound. If terminals appear dirty, clean surface areas of the exposed terminalswith a non-abrasive cloth and recoat with NO-OX-ID A® (provided with accessory kit).
If the case is dirty when removed from the shipping container, clean the case with a cloth dampened with water before installing it in the battery stand.

Caution: Use only water to clean batteries.

Gently slide batteries into position as determined in Step 1. The battery should be oriented so that the nega­tive (-) post of one battery is adjacent to the positive (+) post (post of opposite polarity) of next or adjacent battery.

 

Caution: Do not lift the battery (ies) alone or with one handle. Two persons are always
              required to lift the battery. Hoist battery on pallets or use lifting sling with spreader bar.

 

Coat inter-battery bus bars, provided with battery kit, with NO-OX-ID A® before assembling them to batteries.
Using 1/4-20 hardware and inter-battery bus bar pro­vided, connect batteries into strings as determined in
    Step 1. (See Figure 2), Torque connections to 60 in-Ibs.
Using cabling provided with the plant, connect the battery string to the plant bus as determined in Step 1. Terminate these cable leads with the appropriate wire lugs.

 

Dress the cable leads from the batteries to the plant bus work and torque battery connections to 60 in-Ibs. See specifications provided with the plant for plant bus work torquing requirements.
