Use Of Tle Series 600 & 800 As Frequency Converter - GE TLE series 600 User Manual

5.9.6 Use of TLE Series 600 & 800 as Frequency Converter
NOTE !
The UPS needs the connection of the Neutral at the input Bus Bars.
When the TLE Series 600 & 800 is utilized for different output frequency compared to the input
frequency, the Automatic Bypass and Manual Bypass (only if provided by customer) functions are
disabled, therefore the Load cannot be transferred to Mains in case of overload, short circuit, or inverter
failure.
In situations 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 eBoost™ Operation Mode
is automatically disabled.

In order to avoid improper operation, only the Rectifier input should be powered (L1-1, L2-1 and L3-1
/ Fig. 5.9.1-1 and Fig. 5.9.3-1), therefore BR1, BR2 and BR3, on the input bus bars MUST BE REMOVED
(see Fig. 5.9.2-2 and Fig. 5.9.4-2).
Special care must be taken in choosing the Fuse Ratings installed in the output distribution (max.
20% of the UPS rated current).
Avoid high inrush current due to transformer magnetisation or motor starting.
NOTE !
At site only a QUALIFIED SERVICE ENGINEER may change a unit, initially delivered
as a Frequency Converter, into a normally operating "standard" UPS.
