3.9.5 UPS functioning as frequency converter
NOTE !
The setup for LP33 Series 80 & 100 when functioning as frequency converter requires a
partic
ular installation and adequate setting of some parameters, (accessible
only through password), and can therefore only be done by a GE QUALIFIED
SERVICE ENGINEER .
When the UPS LP33 Series 80 & 100is delivered as Frequency Converter (different output frequency with
respect to the input frequency), 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 cases where the UPS needs to be powered down for maintenance purposes, the critical Load must
also be powered down during this time.
When the set-up parameters of the UPS are set for Frequency Converter, the ECO Mode operation is
automatically disabled.
The UPS delivered as frequency converter has the following differences:
•
Automatic Bypass disabled by setting of dedicated parameter (access protected by password
reserved to service engineer).
• The handle of the switch Q2 - Manual Bypass is removed to avoid accidental wrong manipulations.
• Utility Bypass disabled by removing the fuse F3 fitted on the board P1 – Power Supply.
WARNING !
In case a UPS delivered as Frequency Converter should be set on site for UPS standard
version, the operation must be performed by a GE QUALIFIED SERVICE ENGINEER.
