Remove Existing Cover & Prep Meter

• Remove the existing index cover

and index from the meter.

• Clean the meter index area

and make sure to remove any remaining parts of the old gasket.

Attach the Tamper Magnet Holder

• On an American meter,

attach the magnet so that the protrusion holding the magnet points down and to the left and the gap in the circle fits around the notch on the meter.

• On a Rockwell meter, attach the

magnet holder so that the protrusion holding the magnet points down and to the left and the inner pin is inserted into the index screw hole.

Inspect IMU

• Inspect the IMU, ensuring that

there is no visible damage.

• Check the front and rear gaskets.

Make minor placement corrections as needed.

– The front gasket should adhere

to the enclosure and keep the screw holes clear.

– The rear gasket should be

attached to the enclosure on the left and right, and remain straight in the middle such that the gasket will seal between the enclosure and meter. The gasket must keep the screw holes clear.

12

Connect Battery Cable Connector

• Gently plug in the battery cable

connector to the PCB, if it is not already connected.

– The connectors are keyed. The

top side of the male connector has a feature that fits into a slot on the top side of the female connector on the PCB.

– Orient the connectors before

attempting to connect.

– Carefully insert the male

connector while holding the opposite end of the female connector. Do not push the male connector without holding the opposite end of the female connector.
