Operating the Device
Chloride Linear Plus Series Rack-mount UPS User Instruction Manual 18
The loads are supplied directly from mains via the inverter. Loads are protected against mains failures and
disturbances.
Battery operation (mains failure)
Fig. 10: UPS Control Panel: “Battery Operation”
In the event of a mains failure, the inverter supplies the loads without interruption; the power is supplied
by the battery.
In this operating mode, an acoustical sound is emitted at intervals of approximately 4 seconds. If the
minimum power level of the battery is reached, the signal is emitted once a second.
Bypass operation (overload > 100%, < 150%)
,for
Fig. 11: UPS Control Panel: BYPASS Operation
In the event of an overload between 105% and 150% of rated capacity, the device switches to bypass and
the inverter is blocked. Power is supplied by the mains supply.
This is not a normal operating state. If the mains supply fails, the loads will no longer be supplied (no UPS
operation).
NOTE: For sustained overloads > 130% of capacity, the output will be disconnected within one hour to
protect the circuitry from overheating.
Parallel operation
Refer to chapter “Paralleling UPS Devices” on page 19.
Remote Power Off
(RPO)
For reasons of safety it is required that UPS Emergency Power Off be effected by removing the
connections between the RPO terminals located on the rear of the UPS next to the Interface COM 3
connector Fig. 5 on page 11 and connecting a switch, having the characteristics of an emergency button,
closed under normal operating conditions and held open mechanically when operated. Once the
emergency condition causing the switch to open has been resolved, open all UPS switches (Input, Output
and Battery) and carry out Switch-on procedure as described above “UPS Start-Up Procedure” on page
14).
