Important safety instructions
The safety instructions in this manual must be observed during all work on the device.
The product has been developed and tested in accordance with international safety requirements. Nevertheless, there are still risks, which may result in personal injury and damage to property. Therefore, pay special attention to the safety instructions mentioned in this chapter in order to avoid these risks at all times.
DANGER
Risk of death due to electrical shock and discharge
During operation, high voltages are present on the live parts and cables inside the product. Touching live parts or cables will result in death or life-threatening injuries from electrical shock.
- Before opening the device, de-energise it and secure it against being switched on again.
DANGER
Danger to life from electrical shock when touching live DC cables
When exposed to light, the PV modules generate a high DC voltage that is applied to the DC cables. Touching live DC cables will result in death or life-threatening injuries from electrical shock.
- Do not touch any exposed live parts or cables.
- Before working, de-energise the device and secure it against being switched on again.
- Wear suitable protective equipment during all work on the product.
CAUTION
Danger of burns from hot housing parts
Housing parts can become hot during operation. Touching hot housing parts can cause burns.
- During operation, only touch the inverter's housing cover.
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.
POSSIBLE DAMAGE
Damage to the device
Potential risk of damage when setting the inverter down. Whenever possible, place the inverter on its back after unpacking.
IMPORTANT INFORMATION
Loss of warranty due to incorrect installation
Observe these instructions when selecting the installation site. Failure to observe these instructions may limit guarantee claims or render them fully null and void.
- Be absolutely sure to maintain the clearance around the inverter in order that the inverter remains cool.
- To mount the inverter, use the wall mount and fastening screws that are suitable for the substrate.
IMPORTANT INFORMATION
Damage to the device and loss of warranty due to installation by unqualified persons
The inverter may only be installed, maintained and repaired by a trained and qualified electrician.
The electrician is responsible for ensuring that the applicable standards and regulations are observed and implemented.
Work that could affect the electrical power system of the relevant energy supply company at the site of the solar power feed-in may only be carried out by qualified electricians expressly authorised (licensed) by the energy supply company.
This includes changes to the factory-preset parameters.
IMPORTANT INFORMATION
Cost saving by using a type A RCD
A type A RCD ≥ 300 mA can be used on the AC side as a residual current device (RCD). Set the compatibility with a type A RCD in the Webserver.
