Provide proper line voltage and phase balance .
Improper line voltage or excessive phase imbalance constitutes product
abuse. Severe electrical component damage will occur.
Electrical shock hazard. Can cause severe injury or death.
Connect only low voltage NEC Class II circuits to terminal block TB2.
Overheating or failure of the gas supply to shut off can
cause equipment damage, severe personal injury or
death . Turn off the manual gas valve to the appliance before shutting off
the electrical supply.
The preferred entrance for power cables is through the bottom
knockouts provided on the unit. If a side entrance is the only
option, a hole may be drilled in the stationary upright.
The minimum circuit ampacity (MCA) is shown on the unit
nameplate . Refer to
Table 6
power wires.
Copper wire is required for all conductors. Size wires in
accordance with the ampacity tables in Article 310 of the
National Electrical Code
are required, it may be necessary to increase the wire size to
prevent excessive voltage drop. Wires should be sized for a
maximum of 3% voltage drop. Supply voltage must not vary by
more than 10% of nameplate. Phase voltage imbalance must
not exceed 2%. (This can be calculated by finding the average
voltage of the three legs. The leg with voltage deviating the
farthest from the average value must not be more than 2%
away.) Daikin suggests contacting the local power company for
correction of improper voltage or phase imbalance.
The power source to the unit must be a balanced 3-phase power
supply, meaning that the voltage and impedance to the line is
matched. Unbalanced voltage and/or current (such as provided
with an "Open Delta" configuration), is likely to result in nuisance
alarms, premature failure of components and it will void
equipment warranty. Daikin does not recommend the use of
Rebel units in facilities with corner grounded delta power .
A grounded conductor lug is provided in the control panel. Size
the grounding conductor in accordance with Table 250-95 of the
National Electrical Code or other applicable code.
In compliance with the National Electrical Code, a 120 V factory
mounted service receptacle outlet is provided. This outlet must
be powered by a field connected 15 A, 120 V power supply,
unless unit power outlet was utilized. Leads are brought into the
unit through the bottom of the main control panel.
