Electrical
Before connecting power to the control, read and
understand this entire document. As-built wiring
diagrams are furnished with each control by the factory
and are attached either to the door of the unit or
provided within a paperwork pouch internal to the panel.
Electrical wiring and connections should be done in
accordance with local ordinances and the National
Electric Code, ANSI/NFPA70. Be sure the voltage and
phase of the power supply and the wire amperage
capacity is in accordance with the unit nameplate.
1. Always disconnect power before working on or near this
equipment. Lock and tag the disconnect switch or breaker
to prevent accidental power up.
2. Make certain that the power source is compatible with the
requirements of your equipment. The installation wiring
schematic identifies the proper phase and voltage of the
source breakers.
3. Before connecting control to power source, verify power
line wiring is de-energized.
4. Secure all wiring to prevent contact with sharp objects.
5. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot
surfaces or chemicals.
6. Before powering up the system, make sure that the interior of the control is free of loose debris,
metal shavings, or shipping materials. `
7. If any of the original wire supplied with the system must be replaced, it must be replaced with type
THHN wire or equivalent.
High Voltage Wiring
1. All high voltage wiring shall be terminated
on the right side of the vertical terminal blocks
located on the right hand side.
2. There are multiple electrical power
sources required for this panel. Refer to
Installation diagrams for details.
3. The hood light wiring will also need to be
wired to terminals as indicated on the installation
diagram.
4. If an ANSUL fire system is present, the
fire system micro-switch will need to be wired to
terminals as indicated on the installation diagram, typically “C1” and “AR1”. C1 is the common
and connects to terminal 1 on the micro-switch. AR1 is the armed state and connects to terminal
2 on the micro-switch. If a CORE fire system is present, this connection is not required.
WARNING!!
Disconnect power before
installing or servicing control.
High voltage electrical input is
needed for this equipment. This
work should be performed by a
qualified electrician.
