Use Of Tle Scalable Series 40 - 150 As Frequency Converter - GE FGC TLE Series Manual

4.8.5 Use of TLE Scalable Series 40 - 150 as frequency converter

NOTE !
The UPS needs the connection of the Neutral at the input Bus Bars.
When the TLE Scalable Series 40 - 150 is utilized for different output frequency compared to the input
frequency, the Automatic Bypass function is 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 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 SEM Operation Mode is
automatically disabled.

Q1
In order to avoid improper operation, only the Rectifier input should be powered (L1-1, L2-1 and L3-1
/ Fig. 4.8.2-1), therefore the interconnection links BR1, BR2 and BR3, on the input bus bars, MUST BE
REMOVED. See pictures above and Fig. 4.8.2-1.
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 magnetization 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.
