Mounting and Connection of the Modular Inverter System
The ribbon cables must be covered to protect them against interference. (See
Chapter 2 - 60.)
If several encoders with a high current consumption (e.g. encoders with EnDat
interface) or the dual-processor MC 422B are connected in conjunction with a
compact inverter or a power supply unit, however, an additional power supply
source might become necessary. The additional UV 105 power supply unit can
be used for this purpose. It is mounted next to the control at its left.
The power supply unit is connected to the dc-link voltage via the conductor bar
of the previous left module. The upper conductor bar also establishes the
ground connection of the dc-link.
The 50-line ribbon cable of the compact inverter / power supply unit for
transmitting the status signals is connected to X69 of the UV 105. The free
ribbon cable of the UV 105 is connected to X69 of the control.
The 5-V power supply (X74) of the UV 105 is connected to the terminals on the
control (X74) by using the litz wires included with the UV 105.
