Bosch Rexroth IndraControl XM21, Operating Instructions Manual

Page: 32 / 76

Use the Bosch Rexroth power supply unit VAP01.1H-W23-024-010-NN, part num-
ber R911171065, for the logic supply. For further information 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 routed separately from lines carry-
ing higher voltages.
All peripherals, such as digital sensors or actuators connected to the interfaces
of the control, also have to comply with the criteria of safety-separated circuits.
The same external power supply unit has to supply the 24 V voltage
supply of the XMx control and the extension modules. Connect the
voltage supply to the XD1 plugs of the XMx control and then bridge
the cables to the power connectors XD1 of the extension modules.
The 24 V voltage supply of the S20 I/O modules may not be
branched off from the XD1 plug of the XMx control, but with an own
connecting cable to the external power supply unit instead.
The 24 V voltage supply has to be grounded. For more detailed infor-
mation, refer to the documentation of the power supply unit.
10.7.2 Voltage supply for the control
The control is supplied via the XD1 plug on the lower left.
Connect the power connector with cables with a conductor cross-
section of AWG 16 (1.5 mm 2 ).
Use only copper wires to connect the connection terminals.
Use only cables approved for temperatures of at least 60°C. In case
of ambient temperatures above 55°C, use cables approved for tem-
peratures of at least 75°C.
Observe the color-coding of the plugs.
Only the "XA-CN01" power connector is permitted to connect the 24
V supply voltage for the IndraControl XM21, XM22 control (see chap-
ter 5.1 "Power connectors, 24 V" on page 6 ).
