2.4.3
Supply voltage connection
2.4.3.1
Version 230 V AC
Safe interruption of both supply voltage conductors must be
provided for, either by disconnecting the power connector or
using a separate switch.
The device is protected via two fuses (see Chapter
) on
the back of the device (primary side).
The device is equipped with a wide range power supply and
covers AC systems with a frequency of 50/60 Hz and a volta-
ge range of U
AC
= 100 to 240 V ±10% automatically (without
manual selection).
The power supply is protected against short circuits and
overloads, and disconnects automatically in case of a fault.
If the electrical protection has triggered:
-
Disconnect the device from all power sources and wait at
least 1 minute.
-
Determine and eliminate the cause of the error.
-
Reconnect the device to the supply voltage.
2.4.3.2
Version 24 V DC
This version is designed for U
DC
= 24 V.
The supply is established via two screw terminals (+/-).
The device is protected against incorrect polarity.
The device is protected in the + line via a fuse (see Chap-
ter
) on the back of the device (primary side).
2.4.4
Protective ground connection
2.4.4.1
Version 230 V AC
The device must be connected to a protective ground via a protective grounding
conductor (PE) in the network plug.
The power cable contains a protective grounding conductor which must not be
interrupted inside or outside the device.
The protective grounding conductor is connected to the back of the housing inside the
device.
