Installing the Drive 3-11
DC590+ Series DC Digital Drive
Minimum Connection Requirements
IMPORTANT
If in doubt about the connection of the DC motor to the drive, contact Parker SSD Drives.
NOTE Because of the complexity of showing all possible configurations, this Chapter deals only with a `general purpose’
operation as a basic speed controller. Special wiring options usually form part of a customer-specific system and
connection details will be provided separately.
Minimum connections to operate the drive safely are shown using bold lines in the following circuit diagrams. These connections are
highlighted in text with the symbol opposite. The remaining connections are not necessary for a “quick start-up”.
The Drive is using the default Armature Voltage feedback when following the `minimum connection’ instructions.
WARNING
Power terminals carry an electrical voltage which can be lethal. Never work on any control equipment or motors
without first removing all power supplies from the equipment.
Caution
Make sure all wiring connections meet or exceed applicable local and National Electrical Codes. Be sure to fit branch circuit
and motor overload protection.
IMPORTANT
If fitting your own "Power On" indicator lamp, annunciator, etc., this should be switched by an auxiliary contactor of the
main contactor, not by the controller auxiliary relay.
To avoid damaging the drive NEVER carry out high voltage resistance or dielectric strength tests without first completely disconnecting the
drive from the circuit being tested.
