BOX DIMENSIONS & INSTALLATION APPLICATION NOTES
The NECY enclosure was designed with minimal knockouts to provide installers the freedom to add additional conduit feeds to
better meet specific site conditions without locking them into confined positions or preset trade size fittings.
The dimensions provided are for reference only. Verify all clearances with the actual panel and its components in place prior to
performing any added punch-out work. Note: For Canadian configured devices with step-down transformers (for 347V), added
conduit feed access is more constricted as shown by the added step-down transformer.
WIRING INSTRUCTIONS
DE-ENERGIZE THE PANEL BEFORE MAKING ANY WIRING
CONNECTIONS.
DO NOT DISCARD THESE INSTALLATION INSTRUCTIONS.
PLEASE KEEP FOR FUTURE REFERENCE AND OPERATION
INFORMATION.
NOTE: Make certain that high voltage and low voltage
wiring enters the enclosure separately.
High Voltage wiring should be brought into the upper-
right section of the enclosure, inside the high-voltage
compartment.
Low Voltage wire should enter in the low voltage wiring
areas of the enclosure.
Failure to separate high voltage from low voltage wiring
may cause electrical interference.
HIGH VOLTAGE CONNECTIONS
• Always de energize panel before wiring.
• Use only at the listed voltage per panel specs
• All installation service must be performed by qualified
personnel.
WIRING THE POWER SUPPLY
• The Acuity Relay Panel is factory configured with a 120-
277V 50W switching power supply (MVOLT) , and optionally
can be supplied with a 347V to 277V step-down transformer
(CNDV).
• Connect wires to the power supply. You must provide
a dedicated circuit with circuit protection for the power
supply. Earth ground must be connected to the lug labeled
"FOR EQUIPMENT GROUNDING ONLY," located in the high
voltage compartment
• It is recommended that all low voltage wiring be done
with power removed from the system, to protect from
potential shorts during the wiring process.
• All low voltage wiring must be run in separate conduit
from line voltage wiring. DO NOT MIX CLASS 1 AND CLASS 2
CIRCUITS IN THE SAME CONDUIT
• Test all low voltage wiring for shorts to AC ground before
connection to the controller.
APPLYING POWER
• Once the wiring is complete, make certain that the
enclosure is clean of any wire clippings and that no
fragments are present.
• Ensure that there are no loose wires or exposed wires that
could short to other wires or components.
• Power up the unit from the circuit breaker.
