1.3 Supply voltage
Note: Note the safety instructions in “Requirements for connecting electrical
wires” on page 6 .
1.3.1 MACH104-20TX-F...
Supply voltage is connected via a non-heating appliance socket.

1.3.2 MACH104-20TX-FR...
Supply voltage is connected via non-heating appliance sockets.
The supply voltage can be connected redundantly. Both inputs are
uncoupled. The load is not distributed. With redundant supply, the standard
power supply supplies the device on its own. The redundant power supply
becomes active automatically if the standard power supply fails. Normally the
redundant power supply runs in stand-by mode.
The supply voltage is electrically isolated from the casing.

With a non-redundant supply of the supply voltage, the device reports the
loss of a supply voltage. You can prevent this message by applying the
supply voltage via both inputs, or by changing the configuration in the
Management.
