ELECTRICAL REQUIREMENTS
ILL1898-A
INSTALLING THE CONTROLLER CABLE
Seeley International recommends:
•
Not routing data/communication and supply mains voltage
cables in the same conduit.
•
Not cable tying or taping data/communication and supply
mains voltage cables together.
•
A minimum separation distance, as specified by your
local wiring standards, between data/communication and
supply mains cables. In Australia, this minimum separation
distance is 2” (50mm).
Connect one end of the control cable (with ferrite suppressor) to
the cooler electronics box.
Your cooler electronics will have 2 x RJ ports as shown above.
For cooler electronics with 2 x RJ ports, the wall control cable
can be fitted to either.
Installation of the cooler must conform to local electrical rules,
regulations and standards.
Important!
It is a requirement of Seeley International that
all Breezair coolers be connected to a dedicated circuit to
the distribution board, with a separate circuit breaker and
incorporate all pole disconnection switch in accordance with the
local wiring rules.
Electrical supply specifications may vary depending on model
or region. Please refer to the rating label attached to the cooler
for details.
WARNING!
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or a similarly qualified
person in order to avoid a hazard.
INSTALLING THE MAINS POWER CABLE
This cooler contains an electronics module (control box) with
main power supply termination box separated and connected
via a cable and plug assembly.
The point of entry into the cabinet of the cooler is by knockouts
in the pan (reservoir).
Seal the gap between the conduit and the knock-out hole with
silicone sealant after making connections and clamping the
conduit cable.
Important!
Ensure that all electrical connections are tight.
Loose connections will cause overheating that may lead to
machine damage or fire.
Replace all covers on completion of work, using only the screws
supplied.
Do not tamper with factory wiring. Before leaving the job,
a trained, licensed technician must check that the cooler is
operating correctly.
Terminate the power cable outside of the cooler in a junction
box installed nearby. Refer to the field wiring diagram in the
previous section. The fixed wiring must be The fixed wiring
must be fitted with an all pole disconnection switch that breaks
the active (hot) and neutral (common) in accordance with local
wiring rules. It is recommended that the junction box be located
and installed on the dropper (roof jack).
IMPORTANT REMINDER!
Do not route extra-low voltage data/communication and low
voltage supply mains cables without first consulting your local
wiring standards. Routing data/communication cables and
supply mains cables in close proximity can present an electrical
hazard and can be detrimental to the performance of the
product, resulting in intermittent communication errors, locking
up of screens, displays dropping out and inconsistent erratic
operation.
The main power termination box is provided to facilitate easy
wiring connections. Cable glands are provided for ½” ID
conduit.
