4. Mounting
Mount the unit on a DIN rail or by means of a mounting base. Leave enough
space between the unit and the top and bottom of the control cabinet to enable
air circulation to avoid excessive heating.
Take the internal heating of all units into account when mounting several units
side by side. The environmental conditions must be observed for every unit.
Mounting of the sensors:
Adhere to the mounting instructions of the manufacturer.
5. Electrical connection
Terminal connection
Voltage supply (power)
It is only allowed to operate the unit via one of the possible voltage connections,
i.e. either terminals 7/8, AC/DC or terminals 1/2, 24 V DC.
The terminals 1/2 of the 24 V DC supply are directly connected to the terminals of
the sensor supply. The SELV criteria must therefore be met for the DC supply (safe
extra-low voltage, circuit electrically separated from other circuits, not grounded).
The supply cable must be protected externally according to the cross-section used
(max. 16 A).
MONITOR
DL2003:
110...240 V AC/DC
If the transmitters are sup-
plied via an external 24 V DC
power supply the wiring indi-
cated on the following page
is to be observed.
An electrical separation bet-
ween monitor and transmitter
supply only exists for AC mo-
nitor supply (terminals 7/8).
