WARNING!
PERSONAL INJURY AND/OR
EQUIPMENT DAMAGE HAZARD
Never work on any control equipment without first isolating all power supplies
from the equipment.
Protection must be provided by a correctly rated semi-conductor fuse, fitted
upstream of the drive. The fuse must have an I

Wire the plug-in terminal blocks and re-attach to the drive. Refer to the diagrams on
page 11 and page 12.
DO NOT APPLY POWER AT THIS TIME.

EMC wiring:
If the unit is going to be used in the domestic environment, then for
installations in the EU, a supply filter is recommended in order to comply with EN61800-3.
Sprint Electric part number: FRLN16.
Short Circuit Rating
Suitable for use on a circuit capable of delivering not more than 5000 A RMS Symmetrical
Amperes when protected by a Class aR Series semiconductor fuse.
