2.1.3
Connecting the power unit connections
for supply voltage and signal contact
The voltage supply is connected via a 3-pin terminal block with screw locking.
The signal contact is connected via a 2-pin terminal block with screw locking
(1 or 2 locks, depending on the device design).
Note:
For device variants without PoE: The supply voltage in
MACH1040/MACH1140 device types can be connected redundantly with two
power units. Both inputs are uncoupled.
Note:
The supply voltage is electrically isolated from the housing.
MACH 1040 devices without PoE
MACH 1040 device variants without PoE (Power over Ethernet) are,
depending on the device type, equipped with one or two power units of
the following type:
Type “L”
(see page 41 „General technical data“)
Type “M”
(see page 41 „General technical data“)
Note:
For device variants without PoE: For device variants with two power
units, if there is non-redundant voltage supply, the device reports the
failure of one supply voltage. You can prevent this message by applying
the supply voltage via both inputs, or by changing the configuration in the
Management.
MACH 1040 devices with PoE
MACH 1040 device variants with PoE (Power over Ethernet) are
equipped with two power units.
Power unit 2 is a PoE power unit, see product code item 23 in table
(see table 1)
.
You can choose the connections to power unit 1, see product code
item 22 in table
(see table 1)
.
