AC890PX AC Drive
Step 2: Electrical Installation
NOTE Refer to Chapter 9: "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
An external motor overload protective device must be provided by the installer 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.
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.
