Main Power
The CyberOne EC product offering is available in single or
three phase variations and a wide range of voltages. It is
imperative that the unit nameplate be examined to determine
the operating voltage, frequency and phase of the system
(See Figure 11). The nameplate also provides the full load
amps (FLA), the current the unit will draw under full design
load, the minimum circuit ampacity (MCA) for wire sizing,
and the maximum fuse or HACR (Heating, Air Conditioning,
Refrigeration) breaker size (MAX FUSE/CKT BKR) for circuit
protection. The unit’s nameplate is located inside the cabinet
within the electrical box.
NOTE
If the nameplate states MAX FUSE/CKT BKR, it is
required to use fuses or a HACR type circuit breaker
to protect the system. Other protection devices are
not allowed based upon the product listing.
The unit has power and control pilot holes for connection
of the field-wiring conduits. These pilot holes are located
on the CyberOne EC unit based on the configuration. On an
upflow configuration, the pilot holes are located in the top of
the cabinet. On a downflow configuration, they are located in
the floor of the cabinet. A label stating MAIN POWER
INPUT is placed in close proximity. See the installation
drawing provided with your unit for pilot hole locations.
Terminate the main power wires at the line side of the main
power service disconnect switch, located within the electric
box. A separate equipment ground lug is provided within
the electrical box for termination of the earth ground wire.
Figure 11. Sample Nameplate
The unit is provided with terminals for all required field-wiring.
Refer to the electrical drawing supplied with the unit for all
power and control field-wiring. It is important to identify the
options that were purchased with the unit in order to confirm
which field connections are required.
NOTE
Use of copper conductors only is required. Wiring
terminations may become loose during transit of
the equipment; therefore, it is required to verify
that all wiring terminations are secure.
WARNING
Verify power is turned off before making
connections to the equipment.
A main distribution panel must be provided with a manual
fused disconnect switch or HACR type circuit breaker
