Installing the Drive
AC890PX AC Drive
Step 2: Electrical Installation
NOTE
Refer to Chapter 10: "Routine Maintenance and Repair" for details of fitting a module into the drive.
IMPORTANT
Please read the Safety Information on page Cont.3 & 4 before proceeding.
WARNING
During commissioning, remove the fuses (or trip the circuit breaker) on your 3-phase supply.
Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.
Allow at least 10 minutes for the drive's capacitors to discharge to safe voltage levels (<50V).
NOTE
Motor over temperature sensing is required where the motor has a full-load Ampere rating of less than 50% of the
drive output rating; or when the MOTOR STALLED trip is TRUE (TRIPS STATUS::DISABLE TRIPS>>MOTOR
STALLED); or when the STALL TIME parameter is increased above 480 seconds. Motors used in conjunction with
the drive controller shall be provided with PTC sensor(s) or relays suitable for use with the variable speed drive.
Technical details can be found in Chapter 3 Installing the Drive.
Cable Specification
Ensure your wiring is rated for the highest system voltage.
Cable Entry
There are two drive versions: top wire entry and bottom wire entry. Refer to Chapter 2:
"Product Overview" - Component Identification to identify your drive type.
Provide glands for cabling. These should be of at least the same IP rating as the drive in
order to preserve the overall rating for the drive. The removable plates with gaskets in
the top/bottom of the drive should be punched/drilled to match the glands in use.
Maintain maximum separation between power cables and control wiring. Control
wiring should be run in trunking down the left hand side front edge (when veiwed from
the front of the drive).
NOTE
Refer to Appendix C: “Certification for the Drive” for EMC installation options.
