Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Only open the product if the humidity is within the thresholds and the environment is free of
sand and dust.
• Do not open the product during a dust storm or precipitation.
• Close the product in case of interruption of work or after finishing work.
• Only operate the product when it is closed.
• Close tightly all enclosure openings.
• Only use listed rain-tight or liquid-tight conduit fittings to attach the conduits to the product.
Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be
damaged. Moisture can penetrate the product and damage it.
• Only open the product if the ambient temperature is not below -5°C (23°F).
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the product (e.g. by melting the ice with warm air).
• If the product must be opened in freezing conditions, make sure that the DC load-break
switch is free of ice.
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through
electrostatic discharge.
• Ground yourself before touching any component.
DHCP Server is recommended.
The DCHP server automatically assigns the appropriate network settings to your nodes in the
local network. A manual network configuration is therefore not necessary. In a local network,
the Internet router is usually the DHCP server. If the IP addresses in the local network are to be
assigned dynamically, DHCP must be activated in the Internet router (see the Internet router
manual). In order to receive the same IP address by the internet router after a restart, set the
MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the
free address pool of the network segment to all network participants to be integrated during
commissioning.
