OM−06492 SE SERIES
PAGE B − 5 INSTALLATION
The earth surrounding the ground rod or plate
must contain enough moisture to make a
good electrical connection. In dry or sandy
areas, pour water around the rod, or consult
qualified personnel to devise a method of im-
proving the connections.
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Make certain that the recep-
tacle or optional enclosure is properly
grounded after installation.
Pump Power Cable Connections
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Obtain the services of a
qualified electrician to make all electri-
cal connections. Make certain that the
pump and receptacle or optional enclo-
sure are properly grounded.
The pump is provided with a 50 ft. (15,2 m) power
cable (see Table B-4 for standard power cable
specifications) with one end wired into the pump
head. The other end terminates in separate leads
which must be connected to a control box or switch
box.
Optional rainproof starting switches are available
from the factory (see the parts list, Section E).
NOTE
The optional rainproof starting switch listed in the
Parts List is not designed to be watertight and must
not be used in submerged applications.
Splicing of the power cable is not recommended
by the Gorman-Rupp Company due to safety and
warranty considerations. If a longer power cable is
required, it should be of continuous length and
should replace the existing cable. Any replace-
ment cable must be to Gorman-Rupp standards,
and must be approved by Gorman-Rupp.
Never attempt to alter the length or re-
pair any power cable with a splice. The
pump motor and cable must be com-
pletely waterproof. Injury or death may
result from alternations.

When necessary to change or connect the pump
power cable to a control box, make certain the in-
coming power is OFF and LOCKED OUT. Make
certain the control box is PROPERLY GROUNDED
and that the electrical data on the control matches
the motor name plate data.
Connect the pump power cable to the control
switch as shown in the wiring diagram at the end
of this section. Make certain that all connections
are tight and that cable entry points are rainproof.
