1100E, 1500E, 1800E USER MANUAL SECTION 4
44
• The compressor and drive should be provided with
a proper grounding conductor/earthed in accor-
dance with both local and National Electrical Code
(NEC) requirements.
• Installation of this compressor must be in accor-
dance with recognized electrical codes and any
local Health and Safety Codes.
• Feeder cables should be sized by the customer/
electrical contractor to ensure that the electrical cir-
cuit the system is connected to is balanced and not
overloaded by any other electrical equipment. The
length of wiring from a suitable electrical feed point
is critical as voltage drop may impair the perfor-
mance of the compressor.
• Feeder cable connections to incoming terminals
L1- L2-L3 should be tight and clean.
The applied voltage must be compatible with the
motor and compressor data plate ratings.
• A starter hole is provided for incoming power con-
nection. If it is necessary to make a hole in the con-
trol box in a different location, care should be taken
to not allow metal shavings to enter the starter and
other electrical components. If another hole is used,
the original hole must be blocked off with a suitable
knockout seal.
• A few electrical checks should be made to help
assure that the first start-up will be trouble-free.
1. Check incoming voltage. Be sure that the
compressor is wired for the correct incoming
voltage.
2. Check the motor starter for correct size,
properly sized overload relay, and correct
heaters for the load.
3. Check all electrical connections for tight-
ness. Check all grounding connection for
bond.
4. “DRY RUN” the electrical controls by discon-
necting the three (3) motor leads from the
starter. Energize the control circuits by
pressing the “I” (START) pad, and check all
protective devices to be sure that they will
de-energize the starter coil when tripped.
5. Reconnect the motor leads and jog the
motor for a direction of rotation check as
explained in MOTOR ROTATION DIREC-
TION CHECK on page 45. Wiring diagram
for standard compressors is supplied with
the machine.
CAUTION
The use of plastic bowls on line filters and
other plastic airline components without
metal guards can be hazardous. Synthetic
coolants or the additives used in mineral
oils can alter their structural integrity and
create hazardous conditions. Metal bowls
should be used on any pressurized system
for safety concerns.
"The Plastic Pipe Institute recommends
against the use of thermoplastic pipe to
transport compressed air or other com-
pressed gases in exposed above ground
locations, e.g. in exposed plant piping." (I)
Sullube should not be used with PVC piping
systems. It may affect the bond at
cemented joints. Certain other plastic mate-
rials may also be affected. (I) Plastic Pipe
Institute, Recommendation B, Adopted Jan-
uary 19, 1972.
NOTE
Customer must provide electrical supply
power disconnect within sight of
machine. The fuse protecting the circuit
and the compressor must be selected in
accordance with the data provided in the
general information section.
DANGER
Lethal shock hazards exist inside. Discon-
nect all power at source and lock out before
opening or servicing.
