8. Make sure that the power source is capable of supplying the correct voltage
and required current to the AC drive.
9. Do not attach or remove wiring when power is applied to the AC drive.
10. Do not inspect components unless inside "POWER" lamp is turned off.
11. Do not monitor the signals on the circuit board while the AC drive is in operation.
12. GS3 series DURA
PULSE
drives cannot be used with single-phase motors.
13. Route the power and control wires separately, or at 90 degree angle to each other.
14.
If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close
as possible to the AC drive. EMI can also be reduced by lowering the Carrier Frequency.
15. If the AC drive is installed in a place where a load reactor is needed, install
the filter close to the T1, T2, and T3 side of AC drive. Do not use a Capacitor,
L-C Filter (Inductance-Capacitance), or R-C Filter (Resistance-Capacitance),
unless approved by AutomationDirect.
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.
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 (SCCR)
Models through 50 hp are suitable for use on a circuit capable of delivering not
more than 5,000 rms symmetrical amperes; 10,000A for models 60 hp through
100 hp. The maximum voltage is 240V for all 230V models, and 480V for all
460V models.
Applicable Codes
All
DURA
PULSE
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" section in A
PPENDIX
A, lists the recommended fuse
part number for each
DURA
PULSE
part number. These fuses (or equivalent) must
be used on all installations where compliance with U.L. standards is required.
