THE
DI
(OPTIONAL) VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The UPS series with separate Bypass ensures a separate connection between the input and bypass lines.
The UPS 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).

THE
ER
(OPTIONAL) VERSION OF THE UPS SERIES DIFFERS FROM THE STANDARD VERSION IN THAT SOME
ADDITIONAL BATTERY CHARGERS ARE USED INSTEAD OF THE BATTERIES.
This series of UPS 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.
