should be de-energized and a lock out tag out
system should be in place before work should
commence to prevent accidental shock or
electrocution when installing.
Retrofitting

Electrician.
The advantage with the ArcSwitch Panel Unit™ is
you can install it during a maintenance outage
period, without increasing the time period
needed for your maintenance outage providing
the installation has been planned accordingly.

secure and tight in the panel.
• The Electrical connections are tight and
secured at the back of the ArcSwitch Meter™.
• The Plug is tight and secured to the rear socket.
• The DC Control Voltage is present at the front
Com socket and Positive Polarity is correct.
• You can now connect the ArcSwitch Meter™ to
the front input jacks and test open close
operations of the main circuit breaker.
You have now Commissioned the remote opening
and closing of your circuit breaker.
Operating
Should only be carried out by a Qualified
Electrician.
The operation of ArcSwitch Panel Unit™
and the ArcSwitch Meter™ operates by
switching the dc positive through a
power relay to the already existing
closing coil and opening coil fitted
internally of the circuit breaker via a
control ArcSwitch Transmitter.
The ArcSwitch Panel Unit™ is paralleled off the
opening and closing button on the front door of
the LV Control compartment. When operating via
ArcSwitch Transmitter the operator should put
maximum distance between them and the circuit
they are switching.
Commissioning of the remote opening and
closing of the system is the sole responsibility of
the system electrical engineer and no
responsibility is implied or taken by the
manufacturer.
