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:
ÎConnect 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.
ÎConnect the mains adapter (pos. 2 / 3) to the DL3
and to a mains socket.
ÎFor 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

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).
ÎConnect the network cable included to the net-
work adapter of the computer or the router.
