This equipment is a relatively complicated apparatus.
During rigging, installation, operation, maintenance,
or service, individuals may be exposed to certain com-
ponents or conditions including, but not limited to:
heavy objects, refrigerants, materials under pressure,
rotating components, and both high and low voltage.
Each of these items has the potential, if misused or
handled improperly, to cause bodily injury or death. It
is the obligation and responsibility of rigging, instal-
lation, and operating/service personnel to identify and
recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure
to comply with any of these requirements could result
in serious damage to the equipment and the property in
IMPORTANT!
READ BEFORE PROCEEDING!
GENERAL SAFETY GUIDELINES
which it is situated, as well as severe personal injury or
death to themselves and people at the site.
This document is intended for use by owner-authorized
rigging, installation, and operating/service personnel. It
is expected that these individuals possess independent
training that will enable them to perform their assigned
tasks properly and safely. It is essential that, prior to
performing any task on this equipment, this individual
shall have read and understood the on-product labels,
this document and any referenced materials. This in-
dividual shall also be familiar with and comply with
all applicable industry and governmental standards and
regulations pertaining to the task in question.
SAFETY SYMBOLS
The following symbols are used in this document to alert the reader to specific situations:
Indicates a possible hazardous situation
which will result in death or serious injury
if proper care is not taken.
Indicates a potentially hazardous situa-
tion which will result in possible injuries
or damage to equipment if proper care is
not taken.
Identies a hazard which could lead to
damage to the machine, damage to other
equipment and/or environmental pollu-
tion if proper care is not taken or instruc-
tions and are not followed.
Highlights additional information useful
to the technician in completing the work
being performed properly.
External wiring, unless specied as an optional connection in the manufacturer’s product line, is not
to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls
and any external wiring must not be installed inside the micro panel. All wiring must be in accor-
dance with Johnson Controls’ published specications and must be performed only by a qualied
electrician. Johnson Controls will NOT be responsible for damage/problems resulting from improper
connections to the controls or application of improper control signals. Failure to follow this warn-
ing will void the manufacturer’s warranty and cause serious damage to property or personal injury.

1. This wiring diagram describes the standard elec-
tronic control scheme for use with YORK Solid
State Starter or Variable Speed Drive. For details
of standard modications, refer to Form 160.76-
PW4.
2. Field wiring must be in accordance with the Na-
tional Electrical Code (NEC), as well as all oth-
er applicable codes and specications. Refer to
product Form 160.76-PW1 or 160.76-PW7 for
eld wiring connections.
Field wiring contacts may have
voltage present when power is
removed. Field wiring contacts
could be connected to external power
sources.
3. Numbers along the left side of the diagram are
line identication numbers. The numbers along
the right side indicate the line number location of
the relay contacts. An underlined contact location
signies a normally closed contact.
4. The main control panel class 1 eld wiring ter-
minal connection points are indicated by numbers
within a rectangle. The main control panel factory
wiring terminal connection points are indicated
by numbers within a triangle. Components mark-
ings are indicated by numbers within a circle.
Numbers adjacent to circuit lines are the circuit
identication numbers.
5. To cycle the unit on and off automatically with
contacts other than those shown, install a cycling
device between Terminals 1 and 13 (line 38). See
Note 7. If a cycling device is installed, the jumper
must be removed between Terminals 1 and 13.
6. A remote run-stop switch may be connected to
Terminals 1 and 7 (line 32). See Note 7. The re-
mote run-stop (line 32) is operative only in the
remote operating mode.
7. The device contact rating must be 5 mA at
115 VAC.
8. The contact rating is 5 A resistive at 120 VAC or
240 VAC.
NOTES
9. For the wiring diagram of LCSSS or LVVSD, re-
fer to product Form 160.76-PW6.
10. A jumper is installed between Terminals 21 and
24 for normal operation. To check motor rotation
on initial start-up, complete the following steps:
a. Remove the jumper and install a momentary
switch between Terminals 21 and 24.
b. Press the Start key on the display screen on
the control panel.
c. After completion of the prelube sequence,
jog the motor with the momentary switch.
d. When proper rotation is obtained, replace the
momentary switch with a jumper. The mo-
mentary switch must have a minimum con-
tact rating of 1 FLA, 10 LRA at 115 VAC.
A temporary momentary switch
or jumper is the only connection
permitted between Terminals 21
and 24. Connections of any other
devices to either Terminals 21 and
24 may cause inadvertent compressor
start-up.
11. Solid state motor overload contact (CM) LCSSS
is set up to trip at 105% FLA.
12. Contact rating is 5 A resistive at 250 VAC and
30 VDC, and 2 A inductive (0.4 PF) at 250 VAC
and 30 VDC.
13. Field connected control power supply is not re-
quired, as control transformer is supplied on the
solid state starter and the medium voltage variable
speed drive.
14. The maximum allowable current draw for the sum
of all loads is 2 A holding, 10 A inrush.
15. Each 115 VAC eld-connected inductive load,
that is relay coil, motor starter coil, and others,
must have a transient suppressor wired in parallel
with its coil, physically located at the coil. Spare
transient suppressors and control circuit fuses are
supplied in a bag attached to the green ground
screw located in the lower left corner of the con-
trol panel.
