Electrical Connection
When making electrical connections, use care to apply minimal strain to the electrical
switching element. Refer to wiring schematic below for terminal and wire codes.
Ensure that wiring conforms to all applicable local and national electrical codes and
install unit(s) according to relevant national and local safety codes.
The Switching Element Assembly has been precisely positioned in the
housing at the factory for optimum performance. Any inadvertent movement
or replacement in the fi eld will degrade performance and could render the
device inoperative, unless factory authorized procedures are followed.
