Installing the Drive 3-11
DC590+ DRV Series DC Digital Drive
Protective Earth/Ground (PE)
IMPORTANT
The drive and filter (if fitted) must be permanently earthed/grounded. Each conductor used for permanent
earthing/grounding must individually meet the requirements for a protective earth/ground conductor.
For installations to EN 60204 in Europe:
• For permanent earthing, the drive requires either two individual incoming, protective earth conductors (<10mm²/6AWG cross-section), or one
conductor (≥10mm²/6AWG cross-section) connected to an independent earth/ground point near the drive. Refer to Appendix B: “Certification” -
EMC General Installation Considerations.
The DC590+ DRV DC Digital Drive has ground terminals for each incoming and outgoing supply. A substantial connection must be made to the
incoming supply ground terminal near terminals L1, L2, L3. The ground terminals at the bottom of the drive can be used for armature ground and
grounding the auxiliary 120 VAC loads.
3-Phase Mains Supply (L1, L2, L3)
Connect the main AC power supply to terminals L1, L2 & L3 through the correctly sized branch circuit protection and an AC line reactor or dedicated
drive isolation transformer.
IMPORTANT
You must provide branch circuit protection, rated for the supply voltage: AC Current = 0.83 x DC Armature Current
1-Phase Auxiliary/Control Supply (L, N)
Frame 1 and 2 DC590+ DRVs require an external 120 VAC supply to power the control electronics. This supply is fused at 3 Amps. Connect to
terminals L and N on the terminal board. These drives can also be ordered with an internal Control Transformer option. This option is described on
page
3-44.
Frame 3 and larger DRVs have an integral 120 VAC control transformer. No external connections are required. It works on 230 and 460 VAC
supplies by changing the taps on the transformer.
Motor Armature (A+, A-)
NOTE If in doubt about connection of the DC motor to the drive, check with Parker SSD Drives.
Connect the motor armature to terminals A+ and A-. To comply with national and local electrical codes, external DC overload protection must be
provided.
Connect an earth from the motor to the DRV grounding point. Run the motor protective earth/ground connection in parallel with the motor supply
conductors, ideally in the same conduit/screen/armour.
Make screen connections between the motor casing and the earth connection on the terminal rail. Refer to Appendix B: "Certification" - EMC General
Installation Considerations.
If you are using dynamic braking to stop the motor, connect the negative armature lead through a suitably rated dynamic brake resistor to terminal
DB+. Refer to Dynamic Braking Option below.
