General
The shields of the I/O cables should be grounded to the chassis of the cubicle as close to the RDCU as possible.
Use grommets at all cable entries.
Handle fibre optic cables with care. When unplugging fibre optic cables, always grab the connector, not the cable itself. Do not touch the ends of the fibres with bare hands as the fibre is extremely sensitive to dirt.
The maximum long-term tensile load for the fibre optic cables included is 1 N; the minimum short-term bend radius is 25 mm (1”).
Digital/Analogue input/output connections
See the Firmware Manual of the application program in question.
Installation of optional modules
Follow the instructions given in the user manual of the module.
Other connections
See also the wiring diagram below.
Powering the RDCU
The RDCU is powered through connector X34. The unit can be powered from the power supply board of the inverter (or IGBT supply) module, provided that the maximum current of 1 A is not exceeded.
The RDCU can also be powered from an external 24 V DC supply. Note also that the current consumption of the RDCU is dependent on the optional modules attached. (For current consumption of optional modules, see their respective user manuals.)
Fibre optic connection to inverter/IGBT supply module
Connect the PPCS link of the AINT (ACS 800 series modules) board of the inverter (or IGBT supply) module to fibre optic connectors V57 and V68 of the RDCU.
Note: The recommended maximum distances for the fibre optic link is 10 m (for plastic [POF] cable). In case longer distances are required, contact an ABB representative.
