Preparing for installation
Improperly grounded motors are shock
hazards. Make sure all the equipment is properly grounded.
WARNING: All wiring and electrical connections must be
performed by a qualiﬁ ed electrician familiar with industrial
motor controls. Installations must be in accordance with
local and national codes.
WARNING: Disconnect, tag, and lock out the power
source, and then release all pressure from the system
before attempting to install, service, relocate, or perform
WARNING: Overheating, short circuiting, and ﬁ re damage
will result from inadequate wiring.
IMPORTANT: Damage to the motor from improper
electrical voltage or connection will void the warranty.
This product must be grounded. If the unit comes with a factory
installed cord, plug the cord into a properly sized, grounded
outlet. For units that do not have a factory installed cord, install
permanent wiring from the electrical source to the pressure switch
with a ground conductor connected to the grounding screw on the
pressure switch. A properly sized cord with a ground conductor
and plug may also be installed by the user.
Local electrical wiring codes differ from area to area. Source
wiring and protector must be rated for at least the amperage and
voltage indicated on the motor nameplate, and meet all electrical
codes for this minimum. The minimum wire size should also meet
all electrical codes, and wiring used up to 75 ft. long must be
10 AWG. Use a slow blow fuse type T or a 240-Volt double-pole
circuit breaker (1).
