8. Maintenance
This chapter explains how to switch OFF and discharge the inverter safely. It also provides an
overview of important regular maintenance procedures to ensure trouble-free operation of the
THEIA HE-t inverters. Finally, it is explained how to remove and return the inverters.
8.1. Switch-Off
Always turn OFF and disconnect the inverter in the following order prior to maintenance
work or repairs:
AC Side
• Turn OFF the AC circuit breaker(s).
DC Side
• Turn OFF the DC switch.
• Disconnect the connectors.
• Discharge the DC capacitor bank (See 8.1.1. Discharge).
DANGER: Never work on live wires!
Never perform work on the inverter without disconnecting both the DC and AC side
because of deadly voltages present at the terminals.
DANGER: Discharge the inverter completely prior to service or
maintenance!
High voltages are still present inside the inverter after switch OFF because of a
charged capacitor bank. It must be discharged before performing service or
maintenance work on the inverter.
