11. Do not monitor the signals on the circuit board while the AC drive is in operation.
12. For the single-phase rated AC drives, the AC power can be connected to any two of the
three input terminals R/L1, S/L2, T/L3.
Note: This drive is not intended for the use
with single-phase motors.
13. Route the power and control wires separately, or at 90
angle to each other.
14. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close
as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.
15. If the AC drive is installed in the place where a load reactor is needed, install the filter
close to U/T1, V/T2, W/T3, side of AC drive. Do not use a Capacitor or L-C Filter
(Inductance-Capacitance) or R-C Filter (Res istance-Capacitance), unless approved by
Delta.
16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with sensitivity
of 200mA, and not less than 0.1-second detection to avoid nuisance tripping.
