Installation Procedure:
The AMM-C Ammeter is placed in series with the transformer (Tab #4) and output fuse.
Before installing the ammeter, disconnect the black wire connected to the rear-most section
of the fuse holder (the other end of this wire is connected to Tab #4 on the transformer).
Insert the AMM-C partially into the slot on the fuse / meter bracket, making sure that the
0-Amp reading is at the bottom. For shelf mount installations, use slot shown.
Partially place the meter pressure clip so it just catches the meter. Keep the AMM-C free
to easily reach the wire connections. The teeth on the pressure clip should face the rear
of the ammeter.
Connect the wire removed in step 1 to the upper terminal of the AMM-C.
Connect the 8" wire to the rear-most terminal on the fuse holder. Connect the other end
to the lower terminal on the AMM-C.
Fully insert the AMM-C into the slot and slide the pressure clip completely forward until it
contacts the underside of the fuse/meter bracket.
Reconnect the APX to line power and test the AMM-C for proper operation.
