WARNING
HIGH VOLTAGE
is used in the operation of this equipment.
DEATH OR SERIOUS INJURY
may result if personnel fail to observe safety precautions.
Work on electronic equipment should not be undertaken unless the individual(s) have been trained
in the proper maintenance of equipment and is (are) familiar with its potential hazards.
Shut off power supply to equipment before beginning work and follow lockout procedures. When
working inside equipment with power off, take care to discharge every capacitor likely to hold dan-
gerous potential.
Be careful not to contact high voltage connections when installing or operating this equipment.
LOW VOLTAGE
DO NOT be misled by the term “low voltage”.
Voltages as low as 50 volts may cause death.

NOTES:
1. Minimum circuit ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the rated load
amps for all other loads included in the circuit, per N.E.C. Article 430-24. If a Factory Mounted Control Transformer
is provided, add the following to the system #1 MCAvalues in the YCAS Tables: -17, add 15 amps; -28, add 12 amps; -40,
add 7 amps; -46, add 6 amps; -58, add 5 amps.
2. The recommended disconnect switch is based on a minimum of 115% of the summation rated load amps of all the loads
included in the circuit, per N.E.C. 440 - 12A1.
3. Minimum recommended fuse size is based on 150% of the largest motor RLAplus 100% of the remaining RLAs. Minimum
fuse rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
4. Maximum dual element fuse size is based on 225% maximum plus 100% of the rated load amps for all other loads included
in the circuit, per N.E.C. 440-22. Maximum fuse rating = (2.25 x largest compressor RLA) + other compressor RLAs +
(# fans x each fan motor FLA).
5. Minimum recommended circuit breaker is 150% maximum plus 100% of rated load amps included in the circuit. Minimum
circuit breaker rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
6. Maximum circuit breaker is based on 225% maximum plus 100% of the rated load amps for all loads included in the circuit,
per circuit, per U.L. 1995 Fig. 36.2. Maximum circuit breaker rating = (2.25 x largest compressor RLA) + other compressor
RLAs + ( # fans x each fan motor FLA).
7. The Incoming Wire Range is the minimum and maximum wire size that can be accommodated by unit wiring lugs. The (1),
(2), or (3) indicate the number of termination points or lugs which are available per phase. Actual wire size and number of
wires per phase must be determined based on ampacity and job requirements using N.E.C. wire sizing information. The
above recommendations are based on the National Electric Code and using copper conductors only. Field wiring must
also comply with local codes.
8. Aground lug is provided for each compressor system to accommodate field grounding conductor per N.E.C.Article 250-54.
A control circuit grounding lug is also supplied. Incoming ground wire range is #6 - 350 MCM.
9. The field supplied disconnect is a “Disconnecting Means” as defined in N.E.C. 100.B, and is intended for isolating the unit
from the available power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load
Break Device.
10. Two-Compressor machineswith single-point power connection, andequipped with Star (Wye)-Delta Compressor motor start
must also include factory-provided individual system circuit breakers in each motor control center. All 3 & 4 Compressor
machines equipped with Star-Delta compressor motor start must also include factory-provided individual system circuit
breakers in each motor control center.
11. Consult factory for Electrical Data on units equipped with “High Static Fan” option. High Static Fans are 3.8 kW each.
12. FLA for “Low Noise Fan” motors: 200V = 8.0A, 230V = 7.8A, 380V = 4.4A, 460V = 3.6A, 575V = 2.9A.
13. Group Rated breaker must be HACR type for cU.L. Machines.

NOTES:
1. Field wiring to be in accordance with the current edition of
the National Electrical Code as well as all other applicable
codes and specifications.
2. Contacts must be suitable for switching 24VDC, (Gold
contacts recommend). Wiring shall not be run in the same
conduit with any line voltage wiring.
3. To cycle the unit on and off automatically with contact
shown, install a cycling device in series with the flow
switch (FLSW). See note 2 for contact rating and wiring
specifications.
4. To stop unit (Emergency Stop) with contacts other than
those shown, install the stop contact between terminals 5
and 1. If a stop device is not installed, a jumper must be
connected between terminals 5 and 1. Device must have
a minimum contact rating of 100A at 115 volts A.C.
5. Alarm contacts are for annunciating alarm/unit malfunc-
tion. Contacts are rated at 115V, 100VA, load only, and
must be suppressed at load by user.
6. See Installation, Operation andMaintenance Manual when
optional equipment is used.
7. Jumper must be installed for three compressor operation.
