2 Safety instructions
The string inverters of the S series contain the latest technological advances and have
been built and tested to meet currently valid product safety standards. However, ignoring
the safety instructions contained in this instruction manual can endanger the user, a third
party or property. The quali ed electrician and the operator of the PV plant can minimise
these risks by following the safety instructions at all times.
DANGER
■ Only quali ed electricians who have already completely read and understood this
instruction manual in advance may install SolarMax inverters.
■ The quali ed electrician is responsible for adhering to the valid local application
installation and safety instructions.
■ Ignoring the installation and safety instructions shall cancel any and all warranty
and liability claims.
■ Touching live parts is life-threatening.
■ Disconnecting plug-in connectors on the DC end during operation arcs can result in
arcs. That is why the MC connectors must remain in place until the DC line has
been disconnected.
■ The inverters must remain closed at all times during operation.
■ The PV generator supplies direct current to the inverter when the PV modules are
exposed to sunlight.
2.1 Appropriate use
The SolarMax string inverters of the S series are designed exclusively to convert the
direct current generated by PV modules into alternating current which conforms to the
parameters of the public grid. Any other use is contrary to the purpose for which the
inverters were designed. Sputnik Engineering accepts no liability for damages result-
ing from using inverters for purposes other than this. Any modi cations to the inverter
performed by the plant operator or the tter without any review or approval by Sputnik
Engineering are prohibited.
