8. Do not attach or remove wiring when power is applied to the AC drive.
9. Do not monitor the signals on the circuit board while the AC drive is in operation.
10. For the single-phase, 200V class AC drives, the AC power can be connected to
any two of the three input terminals L1, L2, and L3. For single-phase, 120V
class AC drives, AC power must be connected to terminals L1 and L2.
Note: This AC drive is not intended for use with single-phase motors.
11. Route the power and control wires separately, or at 90 degree angle to each other.
12. 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.
Motor Operation Precautions
1. When using the AC drive to operate a standard 3-phase induction motor, notice
that the energy loss is greater than for an inverter duty motor.
2. Avoid running a standard induction motor at low speed, which may cause the
motor temperature to exceed the motor rating due to limited airflow produced
by the motor's fan.
3. When the standard motor operates at low speed, the output load must be decreased.
4. If 100% output torque is desired at low speed, it may be necessary to use a
special "inverter-duty" rated motor.
Short Circuit Withstand:
Suitable for use on a circuit capable of delivering not more than 5,000 rms
symmetrical amperes. For all 120V models, the maximum is 120 volts. For all
230V Models, the maximum is 240 volts.
Applicable Codes
All GS1 Series AC drives are Underwriters Laboratories, Inc. (UL) and Canadian
Underwriters Laboratories (cUL) listed, and therefore comply with the
requirements of the National Electrical Code (NEC) and the Canadian Electrical
Code (CEC).
Installation intended to meet the UL and cUL requirements must follow the
instructions provided in "Wiring Notes" as a minimum standard. Follow all local
codes that exceed UL and cUL requirements. Refer to the technical data label
affixed to the AC drive and the motor nameplate for electrical data.
The "Circuit Protection Devices" in A
PPENDIX A, lists the recommended fuse part
number for each GS1 Series part number. These fuses (or equivalent) must be used
on all installations where compliance with U.L. standards is required.
