Grounding and Wiring
Installation and maintenance should only be performed with the circuit
be connected to electrical ground to avoid electrical shock or damage
to the equipment and facility. The installation and wiring must
comply with applicable federal, state or provincial codes and regulations.
Core and coil
ballasts are insulated with a varnish-like material. This material
must be penetrated at the point where the ground connection is made
to ensure a good connection. This connection can be made when mounting
the ballast to the luminaire, by using a star washer in combination
with one of the mounting bolts.
of the Lamp Socket Shells
Canadian Electrical Code (Part 1 (1994) Rule 30-314) requires grounding
of lamp socket shells; refer to the connection diagrams. In circuits
with two lamps in series, the socket shell is non-hazardous, provided
that the removal of the lamp electrically isolates the shell.
