Connecting Input Power (Without an 8720MC-RPS)
These procedures assume you have mounted your 8720MC drive and
components and are ready to wire your AC input power.
To wire drive input power:
1. Prepare the incoming wires for attachment to the AC input
terminals by removing 10 mm (0.375 in.) of insulation.
2. Route the 3 phase power wires (R,S,T) to the TB1 connector. Refer
to figures 2.1 and 2.3 for the location of TB1.

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.
