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
Observe 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 authorized 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 side and wait at least 5 minutes.
Risk of fire due to chemical corrosion!
The aluminum 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 aluminum 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 could heat up during operation.
ž During operation, only touch the housing cover on the device.
Damage to the device from electrostatic discharge
Components inside the unit 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.
Damage to property due to condensation build-up
Faulty storage can cause condensate to form in the device and impair the functionality of the device (e.g. storage out-
side the ambient conditions or temporary relocation from a cold to a hot environment).
ž
Prior to installation, check the inner area for condensation and if necessary, allow it to dry sufficiently before in-
stallation
ž Storage in accordance with the technical data > Environmental data - see manual

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 side
ž
Device temperature monitoring system
ž EMC filters to protect the product from high-frequency grid interference
ž
Grid-side grounded varistors to protect the product against burst and surge impulses
ž Islanding detection (anti-islanding) according to the current standards
