4.1 Mechanical installation
Possible overheating and reduced service life
Observe the minimal clearances for sufficient ventilation.
For inverter dimensions and mounting options refer to separate manual:
i500 Mounting and switch-on instructions
4.2 Electrical installation
Dangerous electrical voltage
Possible death or severe injuries due to electrical shock.
All installation works on the inverter must only be carried out in the deenergised state.
After switching off the mains voltage, the capacitors in the inverter can still be charged. Observe the
waiting time on the inverter label before commencing work.
The integral solid state short circuit protection included in the inverter does not provide branch circuit protec-
tion. Branch circuit protection must be provided in accordance with the National Electrical Code and any addi-
tional local codes.
The inverter (PE) terminals connections must be connected to system earth / ground. Earth / ground impedance
must conform to the requirements of national and local industrial safety regulations and all applicable electrical
codes. The integrity of all earth / ground connections should be periodically checked.
