Installing the Converter
3-13
590+ Series DC Digital Converter
Power Connections cont.
Protective Earth Connections
PE
Connect the
drive's PE
terminal to an
independent
earth/ground
star point.
Connect this
earth/ground
star point to
Protective
Earth.
IMPORTANT:
The drive and filter (if fitted) must be p
permanently earthed. Each
conductor used for permanent earthing must
individually
meet the
requirements for a protective earth conductor.
For installations to EN 60204 in Europe:
x
For permanent earthing, the converter requires either two individual incoming
protective earth conductors (<10mm² cross-section), or one conductor (
t
10mm²
cross-section) connected to an independent protective earth/ground point near the
drive.
x
Run the motor protective earth/ground connection in parallel with the motor supply
conductors, ideally in the same conduit/screen/armour, and connect to an
independent protective earth/ground point near the drive.
Refer to Chapter 12: “Certification for the Converter” -
Screening & Earthing (cubicle mounted, Class B).
Caution
On the Frame 5, both the Master and Slave drives must be individually earthed.
Motor Armature
A+
A-
Connect the
motor
armature to
terminals A+
and A-.
Connect the cable screen to the motor's PE terminal and the earth/ground star point.
Connect the motor's PE terminal to the earth/ground star point.
For EMC compliant recommended cable lengths refer to Chapter 12: "Certification for
the Converter" - Cabling Requirements.
Note:
If the drive is to operate in regenerating mode for long periods, it is
advisable to fit a dc fuse or high speed circuit breaker in the armature
circuit. If in doubt consult SSD Drives.
Motor Field
F-
F+
Connect the
motor field (-)
to terminal F-,
and connect
field (+) to
terminal F+.
Frame 3: Terminals F- & F+ = D3 & D4
Connect the cable screen to the independent earth/ground point.
If the motor has no field connections, is a permanent magnet motor, or if the field is
derived externally, you must inhibit the FIELD ENABLE parameter (Tag No. 170) later
during Set-up.
