connectors (Refer to “Removing the A4 Comms Assembly” on page 99).
3 For Standard or Option #002 models, disconnect the Power Reference Cable
from the Front Panel Assembly.
4 For Option #003 units, disconnect the Power Reference Cable from the
Chassis Assembly (rear panel).

Sensor Cable Assemblies as shown on “Replacing the Rear Panel Power
Sensor Cable Assemblies (Options 002 and 003)” on page 109.

10 Obtain the new Chassis Assembly, and then re- assemble the Power Meter
by following steps 1 to 9 in reverse order.
When replacing the power supply unit in the power meter, ensure that all earth
wiring is reconnected. There are two terminals to check, the first is the force fit
connector to the power supply unit and the second a closed loop terminal
bonded to the chassis with an M3.5 machine screw (use a 9 lb/in T15 screw
driver). All the protective earth wiring can be identified by the insulation color
green with a yellow stripe.
Once re-assembly is complete, the unit must be safety-tested in accordance
with local guidelines and procedures. This safety-test may take the form of an
Earth Continuity Test, Hi-Pot Test, etc.
