The cut-out should be punched with the proper tool and should be free from

burrs. The following figure explains the mounting of the power meter.

Figure 5-2: Mounting

While supporting the power meter from the front, tighten both side clamp

screws in a criss-cross pattern till all slack is taken up and then apply one

full turn. Do not over-tighten. Over-tightening could result in breaking of the

clamps.

The power meter should be separated from other equipments and sufficient

space must be provided all around the power meter, to allow air to rise

vertically around the power meter. Lack of sufficient air for cooling may

result in over heating of the power meter.

NOTE: It is much easier to set up the meter before you mount the power meter on the panel.

See “Quick setup” on page 17 for more information.

Gently slide the power meter

through the cut-out.

Put the mounting clamps back in the power meter

and tighten the mounting clamps screws.

Remove the

mounting clamps

from the power

meter.
