INSTALLATION
UPS DHEA 1000VA (fig.8)
Locate the UPS so that the ventilation outlets are not obstructed.
By the use of a screwdriver turn the dowels on the cable panel (see fig. 11) and remove it.
The following connection points are located on the rear of the UPS:
• Input socket [1]: connect the power supply cable to the supplied connector.
• Output socket [2]: connect the output sockets to the supplied connector.
• Fix the cables to the back panel by the use of supplied dowels (see fig.12).
• Socket for connection of RS 232 (9 pin female) type, computer serial interface [3]: to be used if the diagnostics software is utilized.
• E.P.O. (Energy Power Off) [6]: connect the supplied connector.
• N°3 contact output 2 pin: connect to the supplied connector.
Open a few small windows on the cable panel (see Fig.13).
Place the cable panel on the UPS and, by the use of a screwdriver, turn the two dowels in order to clamp it (see Fig.11).
Check the on/off switches of all the appliances to be connected to the UPS are OFF and connect them to the output extension.
Connect Power cable to the electric panel. Check fase and neutral terminals have
been properly linked.
Switch on the UPS.
UPS DHEA 1500VA (fig.10)
Locate the UPS so that the ventilation outlets are not obstructed.
By the use of a screwdriver turn the dowels on the cable panel (see fig. 11) and remove it.
The following connection points are located on the rear of the UPS:
• Input socket [1]: connect the power supply cable to the supplied connector.
• Output socket [2]: connect the output sockets to the supplied connector.
• Auxiliary selectable output sockets [6]: connect the cables to the supplied connectors.
• Fix the cables to the back panel by the use of supplied dowels (see fig.12).
• Socket for connection of RS 232 (9 pin female) type, computer serial interface [3]: to be used if the diagnostics software is utilized.
• E.P.O. (Energy Power Off) [7]: connect the supplied connector.
• N°3 contact output 2 pin: connect to the supplied connector.

CONTACT OUTPUTS:
The DHEA series of UPS has N.3 contact outputs whose default operation mode can be configured by the costumer. At first these contacts are Normally Open. In UPS DHEA 1500VA they can be programmed using the display.
Contact outputs available are the followings:
• Switchover to battery power;
• Generic Alarm;
• Reserve autonomy.
Contact outputs electrical specifications are the followings:
IMAX = 5A VMAX = 250VAC – 30VDC

WARNING
If the red Status Indicator flashes briefly every 3 seconds after all the connected loads are switched on, it is to signal that the load connected to the UPS is at the limit of toleration.
WARNING
At first, neutral sensor is not enabled OPERATION
UPS DHEA 1000VA: “On line double conversion”;
UPS DHEA 1500VA: Three different operation modes can easily be chosen:
1. “On line double conversion”;
The UPS is first programmed in this operation mode.
2. “Eco mode with signal”: the UPS works in Eco mode (By pass).
The status indicator is green until the load can be supplied by battery power in case mains is not present.
The status indicator becomes green yellow flashing every 10 seconds if the load is too high and can’t be supplied by battery power in case mains is not present.
3. “Eco mode with alarm”: the UPS works in Eco mode (By pass).
The status indicator is green until the load can be supplied by battery power in case mains is not present.
The status indicator becomes green yellow flashing every 10 seconds with an acoustic signal if the load is too high and can’t be supplied by battery power in case mains is not present.
WARNING
Since current dispersion towards earth of all the loads are added together in the UPS protection connector (earth wire), it is essential to check that the sum of these currents does not exceed 2.7 mA for safety reasons, according to standard EN 62040-1-1.
WARNING
Never remove the 230 V power plug whilst the UPS is in operation: this would disconnect the earth protection of both the UPS and of the connected loads.
WARNING
The DHEA series of UPS don’t have internal automatic back feed protection.
1. The DHEA series of UPS must be permanently connected. An appropriate and accessible disconnect device shall be incorporated in the fixed wiring. It's forbidden to connect the UPS to mains power using a traditional plug.
2. The user shall fit a warning label on all primary power isolators installed remote from the UPS area in order to warn electrical maintenance personnel that the circuit feeds an UPS. The warning label shall carry the following wording or equivalent:
ISOLATE UNINTERRUPTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON THIS CIRCUIT
WARNING
It is essential to ensure both that the mains outlet used for the UPS is connected securely to the earth circuit and that a suitable protection is provided as per regulations.
The mains outlet, or the circuit breaker, must be installed near the appliance and must be easily accessible.
