X1: DC 24 V Voltage Supply VAC 30.2
Rexroth IndraControl VAM 12.1/42.1 Machine Control Panels
The IndraControl VAC 30.2 connection module including automatic STOP but‐
ton jumpering is supplied with voltage via X1.1 pin1 or X1.2 pin1. The connected
hand-held terminal is supplied with voltage via X1.1 pin3 or X1.2 pin3. To make
the hand-held terminal engageable or disengageable when it is plugged-on, the
wire link between X1.2 pin1 and X1.2 pin3 hast to be removed and the switching
voltage for the hand-held terminal has to be applied to X1.1 pin3 or X1.2 pin3.
DANGER
For safety reasons, the voltage supply for the connection module (X1.1 pin1,
X1.2 pin1) must be monitored. If the voltage fails, the STOP button at the device
is inoperative.
NOTICE
Use only copper wire (14 to 24 AWG) for wiring the connection terminals. Tight‐
en the screws of the screw terminals with a torque of 2.25 lb in (0.22 Nm).
All internally required voltages are generated with electrical isolation via a DC/
DC converter. The connection is designed as male connector strip S, 3.50 mm
pin spacing, so that cables up to a maximum line cross-section of 1.5 mm
be connected.
The VAC 30.2 is available on the customized variants only and is
already prewired! The connection module is supplied via the U
voltage connection of the VAM 12.1 / VAM 42.1

Technical data of the DC 24 V connection VAC 30.2
NOTICE
The external voltage supply must have a rated voltage of 24 V and must not
exceed an output voltage of 30 V. The 24 V line to the connection module is to
be protected by a 2 A time-lag fusible cut-out.
DOK-SUPPL*-VAM*XX.1***-PR02-EN-P
Risk of injury caused by voltage loss and non-
functioning STOP button!
Destruction of screw terminals, insufficient
contact and loss of UL certification if inade‐
quate wire is used and/or wrong tightening
torque.

Occurs via decoupling diode; the line-side
fuse is activated when polarity reversal oc‐
