Note
•
While making wiring connections at the control terminals ensure that the total cable length does
not exceed 165 ft (50 m).
•
Ensure that the length of any safety related wiring does not exceed 100 ft (30 m).
•
Ensure that the cable length between the keypad and the inverter does not exceed 10 ft (3.04 m).
Cable connections longer than 10 ft (3.04 m) may cause signal errors.
•
Use ferrite material to protect signal cables from electro-magnetic interference.
•
Take care when supporting cables using cable ties, to apply the cable ties no closer than 6 inches
from the inverter. This provides sufficient access to fully close the terminal cover.
