6. Insert an insertion tool into the openings of the
terminal contacts (1).
☑ This releases the terminals.
If you do not receive an insertion tool for operating
the terminal clamps with your replacement
varistors, contact SMA Solar Technology AG. As
an alternative, the terminal contacts can be
operated using a 3.5 mm wide screwdriver.
7. Remove the varistor (2).
8. Insert new varistor (3).
The pole with the small loop (crimp) must be fitted
to terminal A when remounting (3).
9. Align the housing lid vertically.
☑ There is no conductive
connection.
The respective varistor is defective and must be replaced.
Varistor failure is generally due to influences which affect
all varistors similarly (temperature, age, induced
overvoltage). SMA Solar Technology AG recommends
that you replace both varistors.
The varistors are specially manufactured for use in the
inverter and are not commercially available. Spare
varistors must be ordered directly from
SMA Solar Technology AG (see
section 15 ”Accessories” (page 91)).
• To replace the part, proceed to step 6.
