Warnings
WARNING! Only qualified electricians are allowed to do the work described in this
chapter. Obey the Safety instructions on the first pages of this manual. If you

Checking the insulation of the assembly
 Inverter
Every inverter module has been tested for insulation between the main circuit and the
chassis (2700 V rms 50 Hz for 1 second) at the factory. Therefore, do not make any
voltage tolerance or insulation resistance tests eg, hi-pot or megger, on any part of the
inverter.
 AC output cable
Check the insulation of the AC output cable according to local regulations before
connecting it to the inverter.
 DC input cable(s)
Check the insulation of the DC input cable(s) according to local regulations before
connecting it to the inverter.
