DLT-V72 Operating Instructions V2.50 Preliminary 115 / 140
14. Integrated power supply, power supply cable
DLT-V72 is equipped with a galvanically separated, integrated DC power supply unit.
Power is connected to the back of the unit using a Phoenix Contact plug. There is no power switch.

WARNING
Electrical shock due to lack of disconnecting device.
The DLT-V72 does not have any externally accessible switching facility, with which the industrial
PC can be quickly disconnected from the power supply in an emergency.
To be able to quickly disconnected the industrial PC from the power supply in emergency
situations:
 Install an easily accessible disconnecting device close to the industrial PC, e.g. a suitable
load switch for low voltage.

Make sure that the disconnecting device disconnects all power supply lines.

Connection to SELV circuit only The SELV circuit is a secondary circuit that is designed
and protected so that its voltages will not exceed a safe
value both when operating correctly or if a single error
occurs.
