7.7 Completing Installation
Explosion Resistant Vents
Certain cell sizes may have been shipped with GNB Pre-
Vent™ vent/filling funnels in place. These vents have flexible
plastic caps installed for shipping purposes. These caps may
be removed and discarded, or they may be left in place if the
battery environment is dusty. (See Figure 3)
Other cell sizes are supplied with Pre-Vents which are not
shipped in place. A standard screw-type vent is used for ship-
ping purposes. If Pre-Vent units were specified, they would have
been packed separately with other accessories. Remove the
screw-type shipping vents one-at-a-time and install a Pre-Vent
unit before charging. Discard the shipping vent.
Other cell types are supplied with separate explosion resis-
tant vents installed at time of shipment. Separate plastic fill-
ing funnels are supplied along with this type vent. These
funnels also have flexible plastic shipping caps. Here again,
these may be removed and discarded or left in place if envi-
ronment is dusty.
The Pre-Vent assembly and other explosion resistant vents
are designed to prevent external sparks or flames from ignit-
ing and exploding internal cell gases. (See Figure 4).
Electrolyte Withdrawal Tubes
Certain calcium cells are equipped with two electrolyte with-
drawal tubes which are installed in the diagonal corners of
the cell. These permit the taking of specific gravity readings
at a point about one-third from the top of the plates. (See
Section 11.1). Refer to Figure 3.
A flexible shipping cap and shipping plug is installed on each
withdrawal tube. The cap may be removed and discarded
after neutralizing or left in place as dust covers. The red plug
should be discarded.
Plastic Numerals (See Page 16)
Plastic cell numerals and battery terminal polarity labels are
provided for 12-cell batteries of 40 ampere hours and over.
The positive terminal cell is usually designated as cell #1 in
the series string.
Battery-to-Charger Connection
The positive (+) terminal of the battery should be connected
to the positive (+) terminal of the charger and the negative
(-) terminal of the battery to the negative (-) terminal of the
charger.
Battery Warning Statement and Nameplate (See Page 1)
A nameplate is shipped with the parts for each battery sys-
tem. It has a peel-off backing to allow mounting on or near
the battery. Nameplate information should be completed by
the installer at the time of the initial charge and start of bat-
tery operation. The installer must make the contents of the
Battery Warning Statement known to all personnel in the
vicinity of the battery.
