Power Walk - In; Reducing The Load ( At 200V And 208V) - Siel SAFEPOWER-EVO-HF Manual De Instalacion Y Uso

P
OWER WALK
The UPS is equipped as standard with the Power Walk-In mode which can be activated and configured using the
configuration software. When the mode is active, once mains voltage comes back (after a period in autonomous mode),
the UPS goes back to absorbing power from this source in a progressive way in order to avoid having to oversize any
generating set installed upstream from the UPS (due to the breakaway).
The duration of the transitory period can be set from 1 to 125 seconds. The default value is 10 seconds. During the
transitory period, the power necessary is taken partially from the batteries and partially from the mains, maintaining
sinusoidal absorption. The battery charger is only switched back on once the transitory period has passed.
R
EDUCING THE LOAD
In the event that the output voltage between phase and neutral is set at 200V and 208V (see "UPS configuration"
paragraph), the maximum power which can be supplied by the UPS is subject to a reduction compared to the rated
power, as shown below:
