4.3 Connection of the power unit
4.3.1 Connection of the DC bus X1D
ThetinnedcopperbarsconnecttheDCbusofthedi󰀨erentH6devices.Precharging,
power supply and regeneration (if required) is provided by the power supply module.
The electrical connection is made with metal bridges, which must be mounted (as illus-
trated in the photo). A plastic cap must be installed at both ends of the H6 system as
protection against accidental contact.
IftheDCcurrentisgreaterthan350A,thecurrentmustbelimitedtothisvalue
for each DC bus connection X1D and the total current must be divided between
the right and left connection.

4.3.2 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 power supply module, but also an existing voltage source can be
used.
The bridge for the connection of the 24V bus is attached to the devices
andxedwithascrew.
