Interunit

Connections

The various

batteries

may be of different

dimensions

and with different

terminal

configurations.

This and the

anticipated

load determine

the wire size, lugs and

length

of the cable

to be used for the interunit

connectors.

Refer to Table 1 and Figure

6 for the

typical

connection

configuration

and cable

to be used

for each

part number

of DYNASTY

VRLA

battery.

Locating

the

Batteries

the

Rack

The individual batteries should be placed on the rack

tier/shelf

with 1/2" (1.27 cm) spacing between the

units. This is important to assure the inter-unit

connecting

cables properly align with the adjacent

battery terminals and to allow air space for proper

cooling of the batteries.

When the batteries are being placed side to side, all

the batteries should be placed with the terminals of

the same polarity (pas.

or NEG.) to the front of the

tier/shelf.

Refer to Figures 4 and 5.

For stability reasons, the batteries should be placed

on the lowest tiers/shelves

first.

CAUTION:

Do not lubricate the rack rails or battery

containers with grease or other lubricating

compounds.

Certain lubricating compounds

will cause

deterioration

of the battery plastic container and/or the

rack plastic components.

Battery

Terminal

Preparation

To minimize

contact

resistance,

it is important

that the

lead terminals

of the batteries

be cleaned

of any

oxidation

that may have occurred

during

transportation

and storage.

It is most convenient

to clean

them

prior

to placing

them

on the rack.

Figure 6-Typicallnter-Unit

Connections

(See Page 11 For Specific

Battery Models)

Lightly brush the terminal contact surface areas with a

brass bristle brush, or the equivalent,

and then apply

a light coating or the special antioxidant grease, such

as NO-OX-ID or NCP-2, to the surfaces to protect the

lead terminal from further oxidation.

Numbering

the

Batteries

Once

the batteries

are placed

on the racks,

they

should

be numbered

for future

identification

during

maintenance,

etc.

Refer to the system

wiring

schematic

and starting

the battery

that is to be the positive

output

of the

system,

label

it as #1. Then

label the batteries

ascending

sequential

order

as they would

connected

in series.

The battery

at the negative

output

of the system

should

be the highest

number

battery.

If individual

strings

are to be connected

in parallel,

each string

should

be uniquely

identified

(e.g. A, B

and C).

In general, the wire size to be used is:

1. AWG #6 for loads of up to 109 amperes or 190

watts per cell.

2. AWG #2 for loads of up to 190 amperes or 330

watts per cell.

3. AWG #2/0 for loads of up to 298 amperes or

515 watts per cell.

4. AWG #4/0 for loads of up to 400 amperes or

693 watts per cell.

5. 2 each AWG #2/0 for loads of up to 595

amperes or 1032 watts per cell.

Lightly brush and coat with the protective grease the

contact surface area of the battery terminal and

interunit cable lug and assemble the interunit

connection

per the relevant connection diagram of

Table 1. Torque the connection

hardware to that

specified in Table 1.

As all the batteries are interconnected
