1.2 Preliminary Operations
1.2.1 Removing the Packaging and Positioning the Device
On delivery, the packaging must be inspected to ensure that it is whole and that it has not been crushed
or dented. Check in particular that neither of the two impact resistant devices on the packaging is red; if
one of them is red; follow the instructions on the packaging.
The essential details of the device are provided on the shipping document. The marking, weight and
dimensions of the various items making up the packing list are shown.
Check the state of the device by means of a visual inspection of both the inside and the outside. Any
dents seen mean that it has suffered shocks during shipping, which could compromise the normal
operation of the device.
During inspection, you may notice that a flat cable is left unconnected from one of the Circuit Cards on
the back of the inner front door. The Voltage/Frequency Converter is supplied with the paralleling
controls as standard, but the system is shipped with this feature disabled. DO NOT connect this cable for
standalone (non-parallel) operation.
1.2.2 Storage
Place the device in covered premises that are protected from direct contact with atmospheric agents and
dust. The following environmental values are those allowed in the storage area:
Temperature: -13°F to +167°F (-25 to + 75 °C)
Relative humidity: 30-95 % max.
WARNING
For the installation of a battery cabinet, if provided with the unit, follow the instructions given in
the specific manual.
The list of material provided may vary depending on the order specifications. Most systems include the
following: this manual, the installation drawing, the warranty and eventual accessories.
1.2.3 Handling
The equipment must only be handled by adequately trained personnel.
1 Insert the forks of the fork-lift truck in the lower part of the device, from the front or back, and
ensure that they stick out about 12 inches on the other side.
2 Secure the device to the fork-lift before moving it.

003-2532 REV H Page 3
In order to avoid the risk of the device overturning, ensure that it is firmly secured to the
fork-lift truck by means of appropriate ropes before moving it.
When being moved the cabinet should be handled with care; shocks or drops can damage it. Once in
position, remove the packaging carefully in order not to scratch the device.
The packaging should be removed as follows:
1. Cut the bands.
2. Slide away the carton from above.
3. Remove the screws securing the cabinet to the wooden base.
1.2.4 Cooling of the Premises
The recommended operating temperature for the lifetime of the
Voltage/Frequency Converter and of the batteries is between 20
and 25°C. The lifespan of the battery depends on the operating
temperature; with an operating temperature increase from 20°C to
30°C, the lifespan of the batteries is halved.
The airflow inside unit is by the fans located inside (forced
convection) and by the air around the side panels (natural
convection).
In order to ensure proper air circulation measures must be taken
during installation to avoid any obstructions to the free circulation of
air. These include the following:
•Ensure a distance of at least 24 inches from the ceiling, so as
not to hinder air extraction,
•Leave a free space of at least 36 inches at the front of the
equipment to ensure both the circulation of the air and
installation and maintenance operations;
•With natural convection the thermal load is dissipated to the
outside through the walls; thus a cabinet placed against a wall or in a hollow dissipates less heat than
one located in a free environment.
The following rule must be observed:
Leave at least one of the three side walls free: right, left or back.
•The bottom side kick panels must not be mounted for installations where cabinets are placed side by
side.
DANGER

003-2532 REV H Page 4
2. Installation
•Check the Safety Instructions.
•Any incorrect connection or handling may cause damage to the Voltage/Frequency Converter
and/or the loads connected to it. Read these instructions carefully and follow the steps
indicated.
•This system must be installed by a qualified electrician.
2.1 Accessing the terminals
The following operations must be performed while the unit is disconnected from the utility
mains power, switched off and all the input and output power switches on the equipment are
open. Before performing connection, open all the input and output power switches and
check that the unit is completely isolated from all power sources: battery and AC power line.
In particular, check that:
- Input line is completely isolated;
- Battery circuit breaker/disconnect is open;
- All power and load connection switches (SWIN) are in the open position;
- No dangerous voltages are present (use a multimeter).
The first connection to be performed is the protective wire (earth ground cable) which has to
be inserted into the terminal labeled PE. The unit must operate with the grounding system
connected.
WARNING
•Do not connect the output neutral to the input neutral.
•If the input connection is Delta the unit can supply only Delta load.
•The output neutral must not be connected unless the unit is the Wye version supplied
with an input neutral.
•TRANSFORMER BOXES (optional) are available for converting the distribution
systems from 3 to 4 wires.
•If a three-phase non-linear load is connected to the output, the current on the neutral
conductor can reach a value equal to 1.5 times the value of the phase current.
Dimension the input/output neutral cable appropriately taking this fact into account.
•The unit cannot feed from a corner ground or mid-point grounded delta supply source.
•Use only lugs or cables with tin-plated eyes for the connections.
•Ensure correct phase rotation at the input and output terminals
•Ensure correct polarity battery connections
•The Static Bypass switch is disabled for safety precautions
Each model can be configured for a delta input source with a delta connected load or for a wye
input with a wye connected load. An input neutral must be provided if the load requires a
neutral connection (i.e. wye). Refer to the Power Connection terminals diagrams later in this
section for details concerning configuration of the neutral to ground bond
DANGER

003-2532 REV H Page 5
2.2 Single Module Configuration
The unit is designed to work as a Single input Unit.
Figure 2 – Single Input 1-Line (Batteries are optional)

003-2532 REV H Page 6
2.3 Cable Entry
The cables can enter in the unit from the bottom or from the top with the optional (Top Entry Cabinet)
Proceed as follows in order to open the unit
1. Open the door
2. Remove the switch cover panel
3. Remove the bottom cable entry cover plates
4. Drill or punch conduit holes in the cover plates
5. Route the power cable through the bottom to the terminals in base to your configuration (see
Figure 3)
Figure 3 – Bottom Cable Entry Layout

003-2532 REV H Page 7
2.4 Connect of Power Cables
Connect the input, output and battery cables to the terminals as shown in Figure 4 and Figure 5:
Figure 4 – 65-80kVA Power Connection Terminals
For the Input, Output and Battery connections, follow the order from the top to bottom, or right to
left, as described in the boxes. The label marked “N” present on the terminal identifies the
neutral terminal.
The unit is provided with a separate busbar that connects the Neutral Output to the frame
Ground for delta input connection. This is required to meet NEC grounding code for separately
derived neutrals. When a Neutral is provided in a Wye configured input connection the busbar
must be removed.
Once installation has been completed inside the equipment, put the switch cover panel back and close
the door.

003-2532 REV H Page 8

For the Input, Output and Battery connections, follow the order from the top to bottom, or right to
left, as described in the boxes. The label marked “N” present on the terminal identifies the
neutral terminal.
The unit is provided with a separate busbar that connects the Neutral Output to the frame
Ground for delta input connection. This is required to meet NEC grounding code for separately
derived neutrals. When a Neutral is provided in a Wye configured input connection the busbar
must be removed.
Once installation has been completed inside the equipment, put the switch cover panel back and close
the door.

003-2532 REV H Page 9
2.5 Differential (GFI)
If the system protection against electric shock uses a differential current device (Ground Fault
Interrupter), it will have to have the following characteristics:
•Sensitivity 300mA
•Sensitive direct current and unidirectional components (class A or class B)
•Insensitive to transient current pulses
•Delay greater than or equal to 0.1 s.
In the standard version, the neutral from the mains power supply is connected to the output
neutral of the unit.
THE ELECTRICAL SYSTEMS UPSTREAM AND DOWNSTREAM OF THE SYSTEM MUST
BE EXACTLY THE SAME (DELTA-DELTA or WYE-WYE)
When operating in the presence of mains supply, a differential breaker (GFI) installed on the input will
intervene as the output circuit is not isolated from the input circuit.
When operating without mains supply (from battery) the input differential breaker will intervene only if it is
able to switch as a result of leakage current without any voltage at its poles (for example a differential
breaker with an auxiliary relay is not suitable). However it is possible to install additional differential
breakers on the output of the unit possibly coordinated with those on the input.
2.6 Emergency Power off Device (EPO)
The system has an EPO (Emergency Power Off) function. In the event of an emergency, using this
function will cause the unit to shut down the rectifier & inverter and completely disconnect the power to
the load. The Output circuit of the unit should not be considered safe, unless the unit is off and the input
power source to the unit has been removed by opening the input disconnect devices which are external
to the unit, including the battery.
This function can be activated from the button (under a hinged clear plastic cover) on the control panel or
by a remote contact. This button must be depressed and held down until the system shuts down. On the
unit, the jumper on the EPO terminals must be removed, and the wires from the auxiliary contact of the
button must be connected in place of the jumper. The contact must be closed with the button in the rest
position and must open when the button is pressed.
