SEPARATE BYPASS INPUT (OPTIONAL)
THE DI (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The TRIPOWER X31 HE series with separate Bypass ensures a separate connection between the input and bypass lines.
The TRIPOWER X31 HE output is synchronised with the bypass line so as to safeguard against incorrect voltage changeovers in
the alternate phases, in the event of automatic bypass or closing of the maintenance switch (SWMB).
INTERNAL TRANSFORMER
THE OT (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES DIFFERS FROM THE OPTIONAL SMALL SIZE
VERSION IN THAT IT USES AN ISOLATION TRANSFORMER INSTEAD OF THE BATTERIES.
This series of TRIPOWER X31 HE uses an isolation transformer connected to the UPS output terminals.
NOTE: A separate bypass line is supplied on this UPS version.
The transformer is connected to the TRIPOWER X31 HE output terminals, so the values displayed are those of the
quantities measured upstream of the transformer.
The presence of the transformer inside the UPS modifies the system neutral arrangements.
The installation of a remote maintenance bypass parallel to the UPS is incompatible with inclusion of the
transformer. In any event, if the remote maintenance bypass is inserted, make sure, at the time the remote bypass
switch is closed, that the UPS is isolated from the system by opening the input and/or output switches.
ADDITIONAL INTERNAL BATTERY CHARGERS
THE AC (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES DIFFERS FROM THE OPTIONAL SMALL SIZE
VERSION IN THAT SOME ADDITIONAL BATTERY CHARGERS ARE USED INSTEAD OF THE BATTERIES.
This series of TRIPOWER X31 HE must be used together with an external Battery Box and is suitable for applications requiring
long back-up times.
NOTE: A separate bypass line is supplied on this UPS version.
The additional internal battery charger cards are powered directly on mains power and have pseudo-sinusoidal wave form
absorption.
If the input switch is closed but the I/O switch is open (UPS switched off) the battery chargers operate independently.
Open the input switch (SWIN) to totally shutdown the UPS and the additional battery chargers.
