8.1 Safety measures during installation
Observe the following safety instructions when performing the work described in Section Installa-
tion .
Danger
Risk of death by electrocution!
• Only technical professionals may perform the work described in Section Installation .
• Always disconnect all DC and AC cables as follows before starting work on the inverter:
1. Make sure that no neighbouring parts are carrying voltage.
2. Switch off all AC line circuit breakers and secure them against being switched on again.
3. Set the DC circuit breaker on the inverter to position
0
and secure it against being switched
on again.
4. Remove the DC connections (Multi-contact MC4) from the inverter according to the manufac-
turer's instructions. A special tool is required for this.
Warning : The DC cables carry voltage when the solar modules are subjected to sunlight.
5. Pull out the AC plug from the inverter as described in Section 8.9, p. 65.
6. Check that all pins of the AC plug are free of voltage. Use a 2-pole voltmeter for this (do not
use a simple neon phase checker); first check the voltmeter for correct operation.
• Do not connect cables to the inverter until explicitly asked to do so in the instructions.
• Do not open the casing of the inverter.
• Connect only SELV circuits to the RJ45 sockets (RS485 interface).
• Lay the cables such that the connection cannot come loose accidentally.
• When laying cables, ensure that no damage occurs to any of the constructional fire safety meas-
ures in the building.
• Make sure that no inflammable gases are present.
• Observe all applicable installation regulations and standards, national laws and connection values
specified by the regional power supply company.
Caution
Danger of damage to the inverter or power reduction (derating)!
• The mounting location must satisfy the following conditions:
– The mounting location and immediate environment are permanently fixed, vertical, flat, non-
inflammable and not subject to constant vibration.
– The permissible ambient conditions are conformed to; see Technical data Inverter , p. 75.
– The following free spaces must be present around the inverter:
above/below: at least 200 mm
at the sides/in front: at least 60 mm
• Do not install the inverter in areas where animals are kept.
• Do not exceed the maximum connection ratings specified on the inverter type plate.
• The DC cables must not be connected to an earth potential (inverter and grid are not galvanically
isolated).
Note
• Avoid exposing the inverter to direct sunlight.
• The display must be readable on the installed device.
