Depending on a Battery Cabinets’ size, normally based on the number of lead-acid type
batteries required to meet the electrical specifications of the battery system, weight
considerations (e.g. freight elevator and lift truck maximum capacity loads) may preclude
shipping the system fully assembled; that is with the batteries installed and all electrical
connections complete in the cabinet prior to delivery. A large system can be shipped with none
or some of its required number of batteries installed and it will be dependent on the customer to
arrange for installation and wiring of the system upon arrival at its premises. The following
instructions are recommended for final assembly of the battery system:
1.
Whether the Battery Cabinet is empty or partially assembled, it should be located,
mounted and
properly grounded prior to final assembly as instructed in this manual in
sections 7.2.1, 7.2.2
and 7.2.3 respectively.
2.
Review the battery system schematic that is located attached to the inside of a cabinet
door to determine the number of batteries that need to be installed in the cabinet, the
position of these batteries on the shelves, the battery terminal interconnections required
to form the battery string, and the cabling of the battery string to the output circuit
breaker.
3.
Identify and count the cables to be used for the battery string connection to the circuit
breaker and the flexible bus bars used for battery terminal interconnections. Assure that
the parts count meet the assembly requirements.
For safety reasons, the following installation sequence must be followed without
deviation:
4.
Install all the batteries required by the system and secure all battery hold-downs, if any
are required by the Battery Cabinet Model being assembled.
Safety Note! Batteries
are very heavy!
Use appropriate lifting equipment to raise the batteries to the proper
height to insert (slide) them in to the channeled slots on the battery cabinet shelves.
Note! In the following Installation Instruction, torque all cable and bus bar connections
to battery terminals. Proper torque values are noted on the system drawing (that has the
system schematic) and also this value can be found on most battery cases.
5.
Install the main POS and NEG cables from the output circuit breaker to the correct
battery posts on the designated battery units shown in the provided battery system
schematic.
6.
Install all inter-shelf jumper cables: These provide connection between designated
batteries located on adjacent shelves. Refer to the provided battery system schematic.
7.
Using the battery system schematic as reference, install the supplied flexible bus bars
interconnecting adjacent batteries on a shelf; but leave the bus bar connection between
the two batteries in the middle of the shelf un-installed at this time. Repeat this
procedure for each battery shelf.
8.
On a selected shelf, place a Voltmeter between the two battery terminals where a bus bar
was not installed in Step 7. The Voltmeter
must
read zero volts. If true, install the
missing bus bar between the two middle batteries on this tier. If the voltage read is not
zero, STOP THE INSTALLATION……there is a short-circuit fault somewhere in the
battery system. This fault must be cleared before proceeding. Repeat this procedure for
all the battery shelves.
9.
Check the voltage at the Output Circuit Breaker to insure it meets system specifications.
