Note
The use of three phase power with delta connection (as sometimes used in North
Americas and some Asian countries) voids warranty. If the facility has a substation
with any type of delta connection, a grounded Y-configured transformer must be
installed before the robot controller.
Line fusing
There is no integrated fuse inside the OmniCore C90XT controller. Add an external
fuse (time-delay) or circuit breaker (class K) according to full load current, as
marked on the controller nameplate. The following table shows the recommended
rating for an external fuse or circuit breaker.

Residual current
The OmniCore C90XT controller is designed to meet the following requirement of
residual current. When connecting the robot controller to the power supply, an
external earth fault protection (residual current device, RCD) is required based on
the following data.
Residual Current in controller (mA)Robot
< 30 mAIRB 1100
< 30 mAIRB 1300
< 30 mAIRB 910INV
Note
The integrator needs to make the dimensioning of the electrical installation to
meet the local electrical requirements.
