CONNECTION OF THE POWER UNIT

4.2 Connection of the power unit

4.2.1 Connection of the DC bus X1D

The copper bars connect the DC bus of the different H6 devices. Precharging, power
supply and regeneration (if required) is provided by the supply unit. The electrical con-
nection is made with metal bridges, which must be mounted (as illustrated in the photo).
A plastic cap must be installed at both ends of the H6 system as protection against
accidental contact.

4.2.2 Connection of the 24v bus X1C

The 24V bus supplies the control and the driver circuit of the axis module and the power
supply and regenerative unit with 24V DC voltage. Generally this voltage is provided by
the COMBIVERT H6 supply unit, but it can also be used by an existing voltage source.
