NOTICE
Use only copper wires to wire the connection terminals.
The Y-repeater is supplied from a 24 V voltage supply.
Use the Bosch Rexroth power supply unit VAP01.1H-W23-024-010-NN (see
chapter 5.1 "External 24 V power supply unit " on page
mation on the external power supply unit and on the creation of overvoltage
categories, refer to the documentation of the power supply unit.
All lines of the 24 V voltage supply have to be wired separately from lines
carrying higher voltages.
NOTICE
Ensure that the control cabinet PC and the Y-repeater are disconnected from
voltage before wiring.
A PLC usually controls this input. Wire the respective PLC output with input
"SEL" on the Y-repeater.
A PLC usually controls this input. Wire the respective PLC output with input
"ESM" on the Y-repeater.
This input is only available for the Y-repeater VAC01.1S-YD1-
TCES.
The connecting cable is available in different lengths.
Use only cables listed in
CDI interface" on page
The cable lengths allowed at the Y-repeater depend on the display resolution
set at the operator display.
The maximum cable length (from the control cabinet PC to the operator dis‐
play) is 100 m with XGA resolution. Also refer to the different operating
modes of the CDI interface (described in the operating instructions of the rel‐
evant operator display).
The cables on the Y-repeaters must not exceed the following lengths:
DOK-SUPPL*-VAC*01*****-IT04-EN-P
IndraControlVAC 01 Y-Repeater
Destruction of screw terminals, insufficient
contact and loss of UL certification if no cop‐
per wires are used.
