DANGER
Danger to life due to electric shock when live components or cables are touched
High voltages are present in the conductive components or cables of the product. Touching live parts and cables results in death or lethal injuries due to electric shock.
- Do not touch non-insulated parts or cables.
- Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
- Wear suitable personal protective equipment for all work on the product.
Damage to the product
SMA Solar Technology AG recommends a daily visual inspection by the charging station user. The product and the associated components must not display any damage.
- In the case of damage to the product, contact the installer.
Moisture inside the enclosure
In rare cases, due to fluctuations in the ambient temperature and moisture and depending on the setup and installation site, moisture can form and condense inside the enclosure. This is particularly evident in the form of condensation on the inside of the lid, which may also run down to the bottom of the enclosure and collect there. This condensation does not affect the function of the product and presents no danger to the proper operation. In case of a large accumulation of condensation at the bottom of the enclosure, observe the following steps:
- Disconnect the product from voltage sources ( > Disconnecting the product from voltage sources).
- Unscrew the pressure-equalizing membrane so that the water can fully drain ( > View from Below).
- Screw the pressure-equalizing membrane back on.
- Wipe up the condensation with a dry cloth.
- Put the product into operation again ( > Commissioning the Product).
Correct performance of maintenance work
All maintenance work must be performed as described in this document. Deviations from procedures or failure to comply with the maintenance intervals will lead to any guarantee- or warranty claims becoming null and void.
Observance of the maintenance intervals ensures trouble-free operation.
The general maintenance work must be performed on all components of the product according to the required intervals.
Semi-annual inspection (every 6 months):
Procedure:
- Inspect the residual-current device.
- Inspect the charging cable in accordance with VDE 0701/702.
Annual inspection of the overall system (every 12 months) in accordance with Deutsche Gesetzliche Unfallversicherung (DGUV) V3:
Procedure:
- Ensure that the residual current operated circuit-breaker with integral overcurrent protection (RCBO) is working.
- Ensure that the tripping time and operating current of the individual, active conductors are correct.
- Ensure that the protection devices at the network input of the charging station are working.
