WARNING
Before you connect the PowerRouter to the Public AC grid, contact the local utility company. They have to
confirm that it is allowed to connect the system.
CAUTION
Do not connect a generator to the AC grid connection. The PowerRouter does not support a generator.
4.5 Connect the AC local out
See figure 3 for the connection overview.
1. Install an emergency switch between the PowerRouter AC local out and the load.
2. Strip the insulation off the wires. To prevent overheating of the wires, you must use wires with a
conductor size of 4 mm
2
.
3. Pass the wires through the strain-reliefs at the bottom of the PowerRouter.
4. Connect the earth ( ) according local regulations.
5. If you do not connect to a grid, you must install an Insulation Monitoring Device (IMD) see figure 4. Or
install a Residual-Current Device (RCD) / Ground Fault Circuit Interupter (GFCI) see figure 5.
6. Connect the phase (L) and neutral (N) wire from the load to the emergency switch, and from the
emergency switch to the AC local out terminal on the PowerRouter.
7. Tighten the strain-reliefs with a torque between 1.2 Nm and 1.5 Nm.
WARNING
For continued protection against electric shock you must always use an Insulation Monitoring Device (IMD)
or a Residual-Current Device (RCD) / Ground Fault Circuit Interupter (GFCI) for off-grid applications.
CAUTION
• Do not connect multiple AC local outputs parallel.
• Do not connect multiple AC local outputs in 3-phase.
4.6 Connect the solar panels
See figure 14 for the overview of the solar panel connections
1. Make sure the DC Disconnect Switch on the PowerRouter is OFF.
2. Verify that the DC voltage and current of your solar installation do not exceed the maximum values
specified on the type plate of the PowerRouter (600 VDC, 15 A).
3. Check the polarity of the solar panel string by performing a voltage measurement.
4. Use a suitable tool to attach the MC4 plug to the solar panel string wires. Use copper wire (4 mm
2
) for
all wiring from the solar panel string to the PowerRouter. Only use solid or stranded wire. Do not use
fine stranded wire.
5. Connect one string to the left input terminals (use mating MC4 connectors).
6. If applicable connect the second string to the right input terminals (use mating MC4 connectors).
