2.11.3 AMM-C (Ammeter) Photo 2.10.3

The AMM-C Ammeter displays output current to the load. This provides a visual

indication of the load applied to the APC and also aids in determining if an open or

short circuit condition exists.

The AMM-C consists of an Ammeter, pressure mounting bracket, and an 8”

connecting cable complete with spade-lug connectors. This option is not available

for the APL.

CAUTION: BEFORE PROCEEDING, ENSURE THAT THE UTILITY POWER HAS

BEEN DISCONNECTED!

Procedure: Photos 1.11.3.a; .b; .c

1. 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). Refer to photo 2.10.3.a.

2. Insert the ammeter partially into the slot on the fuse / meter bracket. The

ammeter should be inserted so that the 0-Amp reading is at the bottom.

NOTE: For shelf-mount installations, use the other slot.

3. Partially place the meter pressure clip so that it just catches onto the meter.

You will need to keep the ammeter free so wire connections can be easily

reached. The teeth on the clip should face towards the rear of the ammeter.

Refer to photo 3.11.3.b.

4. Connect the wire removed in Step #1 to the TOP terminal of the ammeter.

Refer to photo 3.11.3.b.

5. Connect the 8” length of wire, supplied with the option, to the rear-most

terminal on the fuse-holder. Connect the other end of this wire to the lower

terminal on the ammeter. Refer to photo 3.11.3.c.

6. Fully insert the ammeter into the slot and slide the pressure clip completely

forward until it contacts the underside of the fuse / meter bracket.

7. Reconnect the APC to line power and test the Ammeter for proper operation.
