Configuring the Revenue Meter
When enabled, the revenue meter security system prevents unauthorized
alteration of revenue-related quantities. By default, all revenue meters are shipped
from the factory with the security system enabled. You can temporarily disable the
security to configure your revenue meter. This is done by removing the meter’s
back plate, and placing a jumper into the meter.

Before Disassembling the Meter

Before attempting to remove the back plate of the revenue meter, ensure that the
device is protected against static-electric discharge. To prevent damage to the unit,
wear an anti-static wrist strap at all times.
DANGER
During normal operation of the 7350 ION, hazardous voltages are present which can cause severe injury
or death. These voltages are present on the terminal strips of the device and throughout the connected
potential transformer (PT), current transformer (CT), status input, relay, and control power circuits.
Installation and servicing should be performed only by qualified, properly trained personnel.
1. Open all PT fuses (or direct voltage input fuses) and close all CT shorting
blocks.
2. Turn off all power to the revenue meter and disconnect the Line and Neutral (or
DC power) wires from the Supply Power inputs to the unit.
3. Disconnect all other wiring (or power off all other circuits) that may present
potentially hazardous voltage levels to the unit, such as connections to the relay
outputs.
4. Ensure that all cables still connected to the revenue meter are NOT live.

Inserting the Key

In order to configure the revenue meter, ensure that adequate safety precautions
have been exercised as above.
CAUTION
The components inside the 7350 ION-RM are extremely sensitive to electro-static discharge. To prevent
damage to the unit, wear an anti-static wrist strap at all times when working inside the unit. Failure to use
proper equipment during servicing will void the 7350 ION-RM warranty.
1. Remove the thumbscrews and retainer bars from the unit.
2. Remove the anti-tamper wire seal and four screws on the rear panel.
3. Slide out the rear plate of the device to reveal the unit’s circuit board panels.
4. Locate the two-pin jumper header labeled “J1” on the communications card.
