31.6. Fixing and Connection

WARNING
Installations must always be carried out by appropriately trained and qualified personnel in accordance with normal
metering custom and practice.
The installer is responsible for the choice of connecting cables which must be appropriate for the voltage and
current rating of the meter and for ensuring that the supply is protected by an appropriately rated fuse. Failure to
do so may result in damage or fire.
Refer to the connection diagrams inside the terminal cover, paying particular attention to the auxiliary terminal
configuration.
Isolate all circuits before carrying out the installation.
Refer to the nameplate to ensure that the correct meter is being installed.
Failure to comply with these instructions may result in damage, fire and/or electric shock.
To mount the meter on the meter board
Remove the meter terminal cover.
Fix a 5mm dia. x 13mm long round headed screw into the meter board to accommodate the keyhole fixing aperture at
the back of the meter. Leave the shank of the screw projecting from the board by 4.5 mm.
Hang the meter on the screw and align it to be vertical.
Secure the lower end of the meter to the board using two 5mm dia. x 13mm long round head screws through the
lower mounting holes in the area of the terminal chamber.
Tighten screws just sufficiently to prevent movement of the meter.
WARNING
Do not over-tighten the screws or the meter base may be damaged.
For connecting to the large diameter terminals, wire the meter using appropriately sized, colour-coded cable
according to local applicable standards, strip back the cable insulation by 26mm. The terminal block dimensions on
the AS302P meter have a maximum sectional area of 50mm
Fully insert cables into the terminals so that the insulation butts up into the counter-sunk recesses in the bottom face
of the terminal block.
Using a Number 2 Pozidrive or flat blade screwdriver, tighten the M6 terminal screws to a torque of between 2.2N m
(minimum), 2.8N m (maximum).
Auxiliary terminal connections should be completed with appropriately sized cable.
