Final checks
Before inserting the fuses to switch on the system, check the following parameters:
1.
Check the solar panel wiring.
2.
Check the battery wiring.
Check the connection of loads.
WARNING: Risk of electric shock when fuses are installed
When carrying out any work on the solar panel, loads or battery, make sure that fuses for
the solar system are not installed in the fuse terminal blocks of the control cabinet
electronics.
•
Before carrying out any work on the solar system, remove the three fuses from the
fuse terminal blocks in the control cabinet in the specified order (1. Solar panel,
2. Battery, 3. Loads). This will isolate the voltage sources from the circuit.
•
Once the battery connection has been established and the polarity checked by
inserting the three fuses, the system can be switched on (for order, see Section 5.1).

Install additional radio modules/extension
modules (optional)
Install the additional modules as directed by the respective manufacturer. Phoenix Contact
offers a variety of measuring transducers (see "Ordering data" on page 10-4 and
INTERFACE catalog for information).
WARNING: Risk of electric shock at solar panels
Solar panels can produce hazardous voltages whenever exposed to sunlight. Even when
not in full sunlight.
1. Therefore, when working with solar panels or connecting cables during the daytime,
cover solar panels with an opaque material.
2. Always switch off the solar power system when fitting components, troubleshooting,
guiding through cables and performing repairs (see 5.2 on page 5-2).
Figure 4-14 on page 4-24 shows an example for the cable installation of radio
modules/antennas, battery cables, and solar panels.
Observe the maximum connected load of the system as the intensity of sunlight can vary
considerably (see "Performance of the solar system" on page 1-8).
