Terminal Block Locations for a 22 kW System Module
All 22 kW system module components use IEC terminals for power
connections. You will wire the system and axis modules using the
power terminal block conveniently located at the bottom front of the
system and axis modules. To gain access to the input power terminals,
open the system module door and look in the lower right corner.
Figure 3.12 details the order of the terminal blocks.

Terminal Block for 22 kW System Module
Note: Refer to Appendices A and B for information about three-phase
input fusing and circuit breaker information as related to the
power input. Refer to the section Connecting Your Shunt
Module for information about wiring the shunt module to the
22 kW system module.

ATTENTION: To avoid personal injury and/or
equipment damage, ensure installation complies with
specifications regarding wire types, conductor sizes,
branch circuit protection, and disconnect devices. The
National Electrical Code (NEC) and local codes
outline provisions for safely installing electrical
equipment.
