Step 9 - Check the Installation
To ensure safe operation, check the installation with the power off before operating the
unit. When power is first applied, the direction of rotation, operator speed reference,
and operation under load should be tested.
9.1 Checking the Installation with the Power Off
Perform the following checks of the unit installation with the power off:
1. Turn off, lockout, and tag AC input power to the unit.
2. If an input disconnect is installed, make sure it is in the OFF position.
3. Wait five minutes after disconnecting power and verify that the DC bus has
discharged to zero volts. See Figure 5.2 for the test points used to measure DC bus
voltage.
4. Check that any interlocks installed around the driven machine are operational.
5. Check that there is adequate clearance around the unit. Refer to Figure 2.2.
6. Check that the wiring to the control signal terminal strip and to the power
terminals is correct (Figures 5.2 and 7.1 through 7.14).
7. Check that the setup DIP switches and the rotary switches are set correctly.
8. Check that user-supplied branch circuit protection is properly installed and
correctly rated.
9. Check that incoming AC power is correctly rated.
10. Check that the rating of the transformer (if used) matches the unit requirements
and that the transformer is connected for the proper voltage.
11. Check that a properly sized ground wire is installed and that a suitable earth
ground is used. Verify that all ground leads are run unbroken.
ATTENTION: Only qualified electrical personnel, familiar with the
construction and operation of this equipment and the hazards involved,
should install, adjust, operate, and/or service this equipment. Read and
understand this manual in its entirety before proceeding. Failure to
observe these precautions could result in severe bodily injury or loss of
life.
ATTENTION: After disconnecting input power wait five minutes and
check with a voltmeter to assure that DC bus capacitors are discharged
(DC+, DC-). The voltmeter should read zero volts. Failure to observe
these precautions could result in severe bodily injury or loss of life.
