Function: Gases produced during charging escape through a central opening on side of upper cover. A flame trap is integrated into the this position which prevents the flammable gases in the battery from igniting.
It is extremely important to check that the hose is connected to the central gas venting system and that it has not been disconnected while installing. Only then can the battery vent via the fine mesh flame trap and hose.
The flame trap is comprised of a small round fiberglass mat with a diameter of 15 mm and a thickness of 2 mm. It works on a similar principle to a valve therefore it allows the gases produced in the battery to vent.

Position battery and seat lower lip -1- in clamping strip, as shown.
Retain other lip of battery at battery securing pedestal -4- using hold -down -2- and M8 x 25 bolt -3-.
Tighten bolt -3- to 20 N.m (15 ft lb).
Connect battery positive (+) cable and negative (-) cable or Ground (GND) strap.

Tightening torque (terminal clamping bolt): 5 N.m (44 in lb)
