Wiring the control cabinet and the solar panels

WARNING: Risk of electric shock at solar panels
Solar panels can produce hazardous voltages whenever exposed to sunlight. Even when
not in full sunlight.
• Therefore, when working with solar panels or connecting cables during the daytime,
cover solar panels with an opaque material.
NOTE: Polarity of the solar panels
Label the solar cables clearly with their polarity. Observe the polarity of the solar cables
and connection terminal blocks.
The following items supplied with your solar system are needed (see Figure 1-1 on
page 1-5):
– 2 x cables (length 20 m, cross section 4 mm
– 1 x cables (length 5 m, cross section 4 mm
– 2 x cable gland, M20.

Laying the solar cable

NOTE: Damage to the solar cable
• The solar cable is designed for a maximum connection length of 3 m between the
control cabinet and solar panel. Due to the technical system properties, the solar
cable cannot be extended.
• Install the solar cable so that is does not pose a hazard (e.g., trip hazard).
Phoenix Contact recommends using UV-stabilized cable binders to secure the solar
cable (see "Ordering data for accessories" on page 10-4).
• Operation of the solar panel with damaged connecting cables is not permitted.
1. Screw the (M20) feed-throughs to the control cabinet.
2. Guide the solar cable through the (M20) feed-through.
3. Label the solar cable in line with the required polarity.
4. Attach the solar cable as shown in Figure 4-13.
Around 70 cm of cable are needed for connection in the control cabinet.
