4.2 Electrical connection
Note
Connecting the device to the power sup-
ply must always be the last step of the in-
stallation!
Carry out the connection of the Datalogger
(pos. 1) to other modules in the order de-
scribed below:
Î Connect the data cable (VBus ® , pos. 4) to the
controller (pos. 12) and the DL3 (pos. 1). If neces-
sary, extend the cable using the terminal block
included (pos. 7) and a common two-wire cable.
Î Connect the mains adapter (pos. 2 / 3) to the DL3
and to a mains socket.
Î For a direct connection to a router or a PC, con-
nect the Datalogger to a router or a PC using
the network cable (included with the DL3, pos. 5).
Power supply is carried out via an external mains
adapter. The supply voltage of the mains adapter must
be 100 ... 240 V~ (50 ... 60 Hz).
The mains adapter and a VBus
®
cable are included
with the DL3.

4.3 Connecting the VBus
®
cable
The iSolar DL3 is connected to one or several con-
trollers via VBus
®
cables. The corresponding terminal
allocation is described in the controller manual.
The VBus
®
cable can be extended using the terminal
block included and a common two-wire cable.
VBus
®
connection at the terminals:
1 / 2 = VBus ® connection 1 (slave)
3 / 4 = VBus
®
connection 2 (slave)
5 / 6 = VBus ® connection 3 (slave)
7 / 8 = VBus
®
connection 4 (slave)
9 / 10 = VBus
®
connection 5 (slave)
11 / 12 = VBus
®
connection 6 (slave)
To the VBus
®
connections 1 ... 6, master devices (con-
trollers) can be connected.
4.4 Connecting the sensors
Connect the temperature sensors to the following
terminals with either polarity:
•
⊥ / S1 ... S3 = Temperature sensors S1 to S3
Connect the sensor using a 0(4)-20 mA signal as spec-
ified by the manufacturer to the following terminals:
•
⊥
/ CL = Current loop interface 0(4)-20 mA
4.5 Connecting the network cable
The iSolar DL3 can be connected to a computer or a
router by using a network cable (CAT5e, RJ45).
Î Connect the network cable included to the net-
work adapter of the computer or the router.
ATTENTION!
VBus
®
network malfunction!
Separating the device from the pow-
er supply while the VBus
®
is still con-
nected can lead to a VBus ® network
malfunction!
Î
Separate VBus
®
connections
before separating the device
from the power supply!
