INTEGRAL POWER SUPPLY
(P/N 496309
OR
OPTION G115)
If your gauge is already equipped with the 12 VDC power supply
(Option G115), the wiring is done as follows:
1. Remove the power supply cover and install strain relief.
2. Connect the 115 or 230 VAC power supply leads to Terminals 1
and 2 on the terminals 1 and 2 on the terminal block at the end of
the power supply printed circuit board and feed these through the
strain relief. (See Fig. 6)
3. If the gauge is equipped with an alarm, attach the appropriate leads
to the five terminals on the terminal strip on the gauge printed
circuit board and feed these through the strain relief.
4. Replace the power supply cover and adjust the wires for service
loop. (See Fig.8).
If you are adding a power supply to an existing gauge, the wiring is
done as follows:
1. Remove from the gauge body the plate holding the strain relief
assembly by removing four screws. Detach the two 12 VDC leads
going to the terminals on the short terminal block on the gauge
printed circuit board and remove them from the strain relief
assembly. 2. Remove power supply cover from base and install
strain relief.
3. Attach the power supply base to the gauge body using the four
tapped inserts and the four screws supplied.
4. Install a black (-) wire from the power supply assembly to Terminal
1 on the short terminal block on the gauge printed circuit board.
Install a red (+) wire from the power supply board to Terminal 2
on the gauge printed circuit board. (Figs. 8 & 9)
5. If the gauge is equipped with an alarm, attach the appropriate leads
to the five terminals on the terminal strip on the gauge printed
circuit board and feed these through the strain relief.
6. Connect the 115 or 230 VAC power supply leads to Terminal 1
and 2 on the terminal block at the end of the power supply
printed circuit board and feed these through the strain relief. (Figs.
8 & 9)
7. Replace the power supply cover, adjust the wire for service loop.
