7.2 PROCEDURES SINGLE TLE SERIES 225 - 500 FUNCTIONING AS FREQUENCY
CONVERTER
When the TLE Series 225 - 500 functions as a Frequency Converter, the Automatic Bypass and Manual
Bypass functions are disabled.
Therefore the Load cannot be transferred to Utility in case of overload, short circuit, or Inverter failure.
In situations where the UPS needs to be shut-down for maintenance purposes, also the Load must be
shut-down or disconnected.
