Making Electrical Connections:
All electrical wiring must be in
ac cor dance with local code, and
only
com pe tent
elec tri cians
should make the in stal la tions. A
set of prints is in clud ed for use
in making the in stal la tion. All
wires should be checked for
grounds with an ohm me ter or
Megger after the connections are
made. This is important, as one
grounded
wire
can
cause
con sid er able trouble. Figure 1
