3-14 Wiring System, Axis, and Shunt Modules, and Motors (for all systems)
Terminal Block Locations for 5 and 10 kW System Module
(Series A and B)
The 5 and 10 kW system module (Series A and B) 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. The maximum wire
size allowed in the terminal blocks is 3.3 mm
2
(12 AWG). To gain
access to the input power terminals, open the system module door and
look in the lower right corner. Refer to Figure 3.10 for terminal block
details.

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 External
Shunt Resistor for information about wiring the optional shunt
resistor to the 5 and 10 kW system modules.

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.
