Connecting mains cable
- Disconnect the power supply from the mains.
DANGER
Risk of death due to electrical shock and discharge!
De-energise device and secure against being switched on again.
- Secure AC connection against being switched on again.
- Switch the DC switch on the inverter to OFF.
- Correctly lay the mains cable from the power distributor to the inverter.
IMPORTANT INFORMATION
Whenever working on the inverter, only ever use insulated tools to prevent short-circuits.
- Install the necessary safety devices – line circuit breakers, residual current circuit breakers – in the mains cable.
CAUTION
Risk of fire due to overcurrent and heating of the mains cable
If mains cables are too small, they can heat up and cause a fire.
- Use a suitable cross-section
- Install line circuit breaker to secure against overcurrent.
- Strip 120 mm of insulation off the mains cable.
- Fit suitable heat-shrinkable sleeves onto the wires. Strip insulation off ends of conductors and crimp the cable ring lug onto the ends of conductors.
- PIKO CI 30:
Remove connection cover screws.
Lead mains cable through connection cover.
PIKO CI 50/60:
Remove screws on the bottom cover and take off the cover.
Lead the mains cable through the feed-through into the terminal compartment of the inverter.
Connect the mains cable to the AC terminal as instructed on the label. IMPORTANT INFORMATION
Make sure that the phases of the AC terminal and in the mains supply match.
The 4-wire AC connection (3L/PE without N) is only possible in symmetrical networks.
- PIKO CI 30:
Attach connection cover to AC connection and screw it tight.
Torque: 1.5 Nm.
PIKO CI 50/60:
Close the inverter and screw the cover tight.
Torque: 3 Nm. - Seal the mains cable with sealing ring and union nut. Tighten the union nut.
- In countries in which a second PE connection is required, connect this at the marked place on the housing (outside).
