CE COMPLIANCE To comply with CE Electromagnetic Compatibility requirements, the circuit
monitor must be installed in a metallic enclosure (switchgear, for example).
For CE compliance, Merlin Gerin Disconnect Breakers Type P25M #21104 or
IEC 947 equivalent must be connected directly to the metering voltage and
control power inputs (figure 3-1).
Note: The disconnect switch must be placed within reach of the circuit monitor
and labeled “Disconnect Switch for Circuit Monitor.”

If control power is derived from the metering voltage source,
no additional disconnect device is necessary.
However, if control power is derived from a separate source,
an
additional
disconnect breaker
must
be installed here
between the control power terminals and the control power
source.
(See inset box at right for detail of additional disconnect
breaker.)
