3 INSTaLLaTION aND COMMISSIONING
CaUTION!
Until all wiring has been verified to be de-
energized for safety reasons, at least two
persons are required during installation.
Verify that all wiring is disconnected from any
energy source during the entire installation.
Use suitable testing equipment.
Read chapters 2 and 4 prior to installation.
Short circuiting, miswiring or reverse polarity
may lead to damage to the Soladin Web DC
Switch, the inverter, the cabling and/or the
connections.
3.1 ThINGS YOU NEED FOR INSTaLLaTION
Make sure you have all the parts you need to install the Sola-
din Web DC Switch:
• This printed user’s manual (included).
• 2 screws to fix the enclosure to the wall.
• Screwdriver to fix the Soladin Web Switch to the wall
• Tools to install the optional grounding wiring.
3.2 INSTaLLaTION STEP bY STEP
1 Fix the Soladin Web DC Switch to the wall, the input
facing downwards. The screw holes are positioned at the
center, 110 mm apart. Use suitable screws and plugs.
2 Mount the optional resistance f
4 Connect wiring from the inverter, check the polarity.
5 Connect the wiring from the PV strings.
6 Check string voltages and polarities.
7 Close the lid securely to prevent moist leaking inside.
Turn the screws clockwise to tighten the lid.
Fix the top screw first, hang the Soladin Web
Switch into position. Then fix the bottom screw.
3.3 COMMISSIONING aFTER INSTaLLaTION
Move the DC switch to the ON position (vertical).
3.4 DE-COMMISSIONING
If it is necessary to take the Soladin Web DC
Switch out of operation, follow these steps:
1 Turn the switch to the 0 (Off) position
2 Disconnect the PV connectors first
3 Disconnect the Soladin connectors
4 Disconnect the optional grounding
Now the DC Switch can be taken off the wall safely.
3.5 MaINTENaNCE
If necessary, use a soft clean cloth to clean the enclosure
of the Soladin Web DC Switch. Never use any liquids, acids
and/or scourers. Examine your electrical installation on a
regular base, at least once a year. Defects such as loose
connections, burnt wiring etc. must be corrected immedi-
ately.

3.6 PV GROUNDING
Depending on the PV panel type, functional grounding is
required. The Soladin Web DC Switch includes material to
ground either the inverter input plus or minus. See figure 3-1.
Use the 100 k Ohm resistor R to connect 2 or 4 to PE.
Follow these steps, using figure 3-1:
1. Make sure no DC is present, refer to chapter 2.
2. Connect the PE terminal to your PE connection.
3. Connect the 100 k Ohm resistor with the PE terminal.
4. Connect the other side of the resistor to 2 (positive input)
or 4 (minus input).
