6.7 Retrofitting a Surge Arrester Type II
The inverter can be equipped ex works with surge arresters, or they can be retrofitted at a later time. The
order numbers for both retrofit kits (1 for input A only, 1 for input A and B) can be found in Section 15.
To carry out retrofitting, proceed as follows:
1. Disconnect the inverter (see Section 9 "Disconnecting the Inverter from Voltage Sources",
page 63).
2. Unscrew the captive screws of the DC lid on the
left-hand side of the connection area.
3. Lift the DC lid up from the bottom to remove it.
4. Plug all surge arresters into the slots provided until
they snap into place with the side latches.
Danger to life due to high voltages in the inverter
Death from electric shock
There is residual voltage in the inverter. The inverter takes 20 minutes to discharge.
• Wait 20 minutes before you open the upper enclosure lid or the DC lid.
