ž Knowledge about how an inverter functions and operates
ž Knowledge about IP-based network protocols
ž
Knowledge of the Modbus specifications
ž Knowledge of the SunSpec Modbus specifications
ž
Knowledge of applicable standards and directives.
ž Knowledge and adherence to this document with all safety notices.
2.5 Residual risks
Lethal voltages are still present in the connections and cables of the device even after the
device has been switched off and disconnected!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
ž The device must be mounted in a fixed position before being connected electrically.
ž
Comply with all safety regulations and current technical connection specifications of the responsible power supply
company.
ž The device is only permitted to be opened and serviced by a qualified electrician.
ž
Switch off the grid voltage by turning off the external circuit breakers.
ž Check that all AC and DC cables are completely free of current using a clip-on ammeter.
ž Do not touch the cables and/or terminals/busbars when switching the device on and off.
ž
Keep the device closed when in operation.
Dangerous voltage due to two operating voltages
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched. The discharge
time of the capacitors is up to 5 minutes.
ž Only appropriately qualified electricians authorised by the mains supply network operator are permitted to open
and maintain the device.
ž Observe warnings on the device housing warning label.
ž Before opening the device: Disconnect the AC and DC sides and wait at least 5 minutes.
Risk of fire due to chemical corrosion!
The aluminium may be destroyed by the copper busbars in the presence of electrolytes (e.g. condensate).
ž Cable lugs must be suitable for the conductor material and copper busbars used.
ž When using aluminium cable lugs, use cable lugs with galvanic tin-plating or AL/CU cable lugs as well as suitable
AL/CU washers.
Risk of burns due to hot housing components!
Housing components can become hot during operation.
ž During operation, only touch the housing cover on the device.
Damage to the device from electrostatic discharge
Components inside the device can be damaged beyond repair by static discharge.
ž
Observe the ESD protective measures.
ž Before touching a component, ground it by touching an earthed object.
Property damage as a result of condensation
During pre-assembly of the device, moisture can penetrate into the interior via the dust-protected threaded connec-
tions. The resulting condensate can cause damage to the device during installation and start-up.
ž
Prior to installation, check the inner area for condensation and if necessary, allow it to dry sufficiently before in-
stallation.
ž Store in accordance with the technical data > Environmental data - see Manual
de/downloads in the „String-inverter/manual" category.
2.6 Monitoring and protection functions
The following monitoring and protection functions are integrated in the device:
ž
RCMU (Residual Current Monitoring Unit)
ž Overvoltage conductor / varistor to protect the power semiconductors from high-energy transients on the grid and
generator sides.
ž
Device temperature monitoring system
ž EMC filter to protect the inverter from high-frequency grid interference
ž
Grid-side varistors grounded to earth to protect the product against burst and surge pulses
ž Anti-islanding detection according to the current standards.
