Remove the Power Supply Wiring
Disconnect the following power supply and control wires from each VFD. The following
instructions relate to either the IntelliPak II, CGAM or RTAC VFD.
1. Disconnect power supply wires from VFD connection points 91, 92, 93 (L1, L2, L3
respectively).
2. Disconnect output power wires from VFD connection points 96, 97, 98, 95 (T1, T2, T3, GND
respectively).
Remove the Control Wiring
Complete the following steps to remove the control wiring.
1. Disconnect all control wires from the TR1 VFD itself and note the connection point numbers.
The TR1 and TR170 have the same connection point numbers. See the following table, which
applies to IntelliPak II, CGAM, and RTAC drives except as noted, for common control wiring
and their connection point numbers.
Table 1. Typical control wires to remove from the TR1 and reinstall on the TR170
