TLE Scalable Series 40 to 150 UL S1
UPS Installation Guide / REV-B
4.8.5
Use of TLE Scalable Series 40 to 150 as Frequency Converter
Note!
The UPS needs the connection of the Neutral at the input Bus Bars.
Permanently running the UPS without Bypass supply requires a change of internal wiring to be
performed by an ABB Service Technician only.
When the TLE Scalable Series 40 to 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.
Fig. 4.8.5-1 TLE Scalable Series 40 to 150 - Interconnection links BR1, BR2 and BR3
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!
Only an ABB Service Technician may change a unit from Frequency Converter into a normal UPS
(with Bypass) or a normal UPS to a Frequency Converter (with Bypass).
