TLE Series 600 & 800 CE S1
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.
Fig. 5.9.6-1 TLE Series 600 & 800 - Power connection for UPS utilized as frequency converter
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.
