Indoors
If you protect the cable from UV radiation outdoors by means of a suitable cable channel, you can
also use a non-UV-resistant (indoor) cable with the basic properties mentioned above.
We recommend the following cable types:
• Lapp cable: Unitronic LiYY 7 x 0.25 mm
2
, order no.: 0028 307
• UL-listed Lapp cable: UNITRONIC LiYY UL/CSA 7 x AWG22/7, order no.: 0022 607
• Helukabel: TRONIC LiYY 6 x 0.25 mm
2
, order no.: 18033
4.2 Selecting the Mounting Location
Consider the following points during the selection of a mounting location:
• The sensor is suitable for outside mounting.
• Select a position that is as level with the solar cells as possible and not shaded during the
daytime.
• Observe the prefabricated cable length of 5 m; the cable must not be shortened.
4.3 Mounting the Irradiation and Temperature Sensor
1. Connect the irradiation and temperature sensor to the bracket using the nuts recessed in the
frame.
2. Lay the connection cable.
☑ The irradiation and temperature sensor is fully mounted.
4.4 Connection Overview
The sensor's wire assignment is as follows:
Wire color Assignment
Green Irradiation sensor +
White Irradiation sensor -
Yellow Temperature sensor PT100
(The sensor's wire assignment can be defined as desired. However, when using a
4-cable system, the connection assignment should be observed)
