ELECTRICAL CONNECTIONS
Obtain the services of a qualified elec-
trician to make all electrical connec-
tions and to service the control box.
The electrical power used in this control
box is high enough to cause injury or
death. Make certain that the control box
is properly grounded after installation.
Make certain that the power source
phase and voltage matches the data on
the control box. Complete all electrical
connections before connecting the
power supply to the control box. Make
certain to ground the appropriate lead
of the power source before connecting
power to the control. Make certain that
the control box is properly grounded af-
ter installation.
Grounding Methods
Electrically ground the installation before connect-
ing the field wiring to the control box. Install a
grounding terminal to the enclosure and connect it
to a properly embedded electrode.
The material used for the electrode must be an ex-
cellent conductor of electricity, such as copper. If
iron or steel is used, it must be galvanized or other-
wise metal plated to resist corrosion. Do not coat
the electrode with any material of poor conductiv-
ity, such as paint or plastic.
The electrode must conform to the recommenda-
tions of N.E.C. ARTICLE 250. Follow all installation
requirements of the N.E.C., and all applicable
codes. See Figure B−2 for some suggested
grounding methods.
