Installing the Converter 3-3
590D DC Digital Converter - HA467078
Electrical Installation
IMPORTANT: Please read the Safety Information on page Cont. 3 & 4 before proceeding.
WARNING!
Ensure that all wiring is electrically isolated and cannot be made “live”
unintentionally by other personnel.
Note:
Refer to Chapter 11: “Technical Specifications” for additional Cabling Requirements and
Terminal Block Wire Sizes.
Cables are considered to be electrically sensitive, clean or noisy. You should already have
planned your cable routes with respect to segregating these cables for EMC compliance.
If not, refer to Chapter 12: “Certification for the Converter”.
If the controller is to be operating in a regenerating mode for extended periods acting as a load
generator for another machine, it is advisable to fit additional protection in the armature circuit.
A dc fuse or high speed circuit breaker will provide this protection. If in doubt, contact Parker
SSD Drives.
Cable Gland Requirements
Use a metal gland to
connect to the cubicle
backplate, near the
VSD (variable speed
drive). It must be
capable of securing a
360 degree screened
connection to give
EMC compliance. A
360 degree screened
connection can be
achieved as shown.
We suggest a rubber
grommet should be
fitted on holes where a
cable gland is not used.
