Metal Surround Case
The meter
’
s plastic case is made from a fire retardant polycarbonate. A metal surround case can be ordered to
enhance the meter
’
s fire retardant capabilities and also provide shielding against electromagnetic interference
(EMI). The metal case slides over the polycarbonate case and is held firmly in place by spring-type non-return
clips. Once the metal case has been fitted to the polycarbonate case it cannot be removed.
With the metal case in place, the meter
’
s plastic ratchet-type mounting clips can no longer be used. A pair of
screw-type mounting clips are inserted into holes on the side of the metal case and used to mount the meter in
the panel. A ground tab on the metal case provides a ground connection between the meter
’
s main board and the
metal case.
**Metal Surround Case must be factory installed.
