Connecting Input Power

Terminal strip TB1 is always the power terminal connection point and
has terminals for both AC input power and DC input power. If you are
using a regenerative power supply input, use the two DC input
terminals. Refer to 8720MC Regenerative Power Supply User Manual
(publication 8720MC-RM001x-US-P) for information regarding
installing the 8720MC-RPS unit. If you have a direct AC input
application, use the three AC input terminals for 3 phase 380 to 460V
ac incoming power and then the two DC terminals for connection to
the active shunt (dynamic brake) module.

Connecting Input Power (With an 8720MC-RPS)

These procedures assume you have mounted your 8720MC drive and
RPS and components and are ready to wire your DC input power.

To wire drive input power:

1. Prepare the incoming wires for attachment to the DC input

terminals by removing 10 mm (0.375 in.) of insulation.

2. Route wires (DC+, DC-) to the TB1 connector. Refer to figures 2.1

and 2.3 for the location of TB1.

3.

4. Tighten the connectors.

5. Gently pull on each wire to make sure it does not come out of its

terminal. Re-insert and tighten any lose wires.

6. Go to Connecting Motor Power.

IMPORTANT

When tightening screws to secure the wires, refer to
DC Drive Power Wiring Requirements for torque
values.

IMPORTANT

To ensure system performance, run wires and cables
in the wireway as established in Chapter 1.

IMPORTANT

Use caution not to nick, cut, or otherwise damage
the wire as you remove the insulation.
