Notice!
+24 VDC power supply
The injector may only be used in conjunction with devices that are supplied with a safe extra-low
voltage device (SELV) per EN 60950.
9.2.5 Power supply (terminal block)
Caution!
It is important to note that the pinout of the power supply differs from other B&R devices. This different
pinout is described in the following table.
In addition, there is an adhesive label with a corresponding note on the injector that must be removed
before connecting the device.
Information:
The tightening torque for securing the terminal block to the injector is 0.15 to 0.20 Nm.

9.2.6 Grounding
The device must always be grounded with a Cat 5 (shielded) cable. Grounding helps to limit the interference effects
on the control system through electromagnetic interference. Another way to perform grounding is to use the screws
near the connector. A label helps to identify the connection as grounding. For a more detailed overview of the
connections and pinout, see the image in the previous section.
All electronic devices in the system must be adequately grounded. Grounding must be carried out in accordance
with applicable regulations.
