1 Safety Information
Danger to life due to high voltages in the inverter
When exposed to sunlight, the PV array generates
dangerous DC voltage which is present in the DC
conductors and the live components of the inverter.
Touching the DC conductors or the live components can
lead to lethal electric shocks.
• All work on the inverter must be carried out by
qualified persons only. Qualified persons must at
least have the following skills:
– Knowledge of how SMA inverters work and are
operated
– Training in how to deal with the dangers and
risks associated with installing, repairing and
using electrical devices and installations
– Knowledge of how to safely disconnect SMA
inverters
– Knowledge of all applicable laws, standards
and directives
• Always disconnect the inverter from voltage sources
before performing any work and secure it against
reconnection.
• After disconnecting the inverter, observe a waiting
time of at least five minutes to allow the residual
voltage to discharge.
• Make sure that there is no externally visible damage
to the spare part.
• Make sure to use only the spare parts provided for
the replacement. Spare parts must only be used for
their intended purpose. In case of uncertainty or if
you have questions concerning the spare part,
contact the Service prior to the replacement (for
contact details, see www.SMA-Solar.com).
• Do not touch any live components of the inverter.
Risk of burns due to hot enclosure parts
The temperature of the cooling elements and components
in the inverter can exceed 70°C/158°F. There is a risk of
burns.
2 Instructions for Replacing the
Fan
NOTICE
It is not possible to replace the fans individually. The
entire fan unit must be replaced.
2.1 Removing the Fan
1. Loosen the three screws (TX 30) from the front cover of
the inverter.
2. Lift the cover by 180°. A magnet enables the cover to
stay open. For information on how to open and close
the inverter, refer to the installation manual of the
STP 60 inverter.
3. Loosen the two black cables which supply the fan with
current: one cable is on the right outside, the other on
the left outside. Figure 1.1 shows the position of the
cables and (1) in figure 1.2 shows how the connector
of the black cables is removed.
Prior to removal of the cable, the snap locks must be
loosened.
