4.8.3 Standby-off (with mains present the load is not powered)
load not powered, in the event of an input mains failure the load is powered from the inverter
using the energy stored by the batteries.
Standby-Off:
if there is a mains power supply, CPS output is zero. The RECTIFIER remains on and keeps the
battery charged. The output voltage is only present when the mains power supply fails. The
system remains with output voltage = 0V while the voltage and the input frequency are within
the acceptance field. When the power supply line is restored, the CPS is automatically
repositioned in
Standby-Off
mode.
The letter
F
will be displayed on the second line of the BASIC MENU, near the CPS model.
4.8.4 Stabilizer (operation in on-line mode without battery)
load powered from the inverter, if there is a mains failure the load is not powered, the batteries
are not present.
Stabilizer:
The load is always powered through the inverter, with stabilized voltage and frequency,
using the energy from the input mains. The batteries are not present. In the event of an input
mains failure, the output of the STABILIZER is not powered.
The letter
S
is displayed on the second line of the BASIC MENU, near the CPS model.
4.8.5 Frequency converter (from 50 to 60Hz or vice versa)
load powered from the inverter with output frequency different from the input frequency; in the
event of an input mains failure the load may be powered from the inverter using the energy
stored by the batteries, if present.
Frequency converter:
MAINS present, load powered. The load is always powered through the inverter, with
stabilized voltage and frequency, using the energy from the input mains. The by-pass line is
disabled and must not be connected (the connections between the main supply line and the
by-pass line on the input bars must be removed).
SWMB
Do not use disconnector SWMB when the CPS is configured as a Frequency Converter.
N.B.
: the disconnector can be padlocked in order to ensure that it is not used.
