CAUTION!
The Sentinel TEG must be isolated from the gas supply piping system by closing its
individual manual shut-off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 0.5 psig [3.5 kPag].

INSTALLING THE START-UP BATTERY FUSE
The start-up battery pack is shipped installed and
connected to the main electronics board. The Sentinel TEG
is shipped with two ceramic fuses as part of the electronics
assembly kit. To activate the start-up battery pack, unpack
one of the two fuses from the electronics assembly kit and
install it into the fuse slot on the battery board as shown in
Figure 11.
The batteries are shipped fully charged; however, they may
slowly discharge during shipping. Before starting the TEG,
check the battery voltage and ensure that it is greater than
11. 8 Volts.
To check the battery voltage, touch the ends of a voltmeter
to the [ + BATTERY – ] terminals at the bottom of the main
electronics board. Refer to Figure 12.
If the battery voltage is too low, then it must be either
charged or replaced. If the start-up battery pack is
depleted, the Sentinel may be jump-started using the TEG
jump start cable offered by GPT. Refer to Section 5.3 for
more information.
