1.2 Preliminary Operations

DANGER

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.

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 uninterruptible power supply, 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.

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.

Page | 3

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 UPS 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 UPS is by the fans located inside the UPS (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.

Page | 4

2. Installat ion

DANGER

• Check the Safety Instructions.

• Any incorrect connection or handling may cause damage to the UPS and/or the loads

connected to it. Read these instructions carefully and follow the steps indicated.

• This UPS must be installed by qualified electrician.

• It is advisable to provide a maintenance bypass switch or an electrical panel with individual

protection for input, output, and static bypass, as well as a manual bypass. This allows isolation of unit during preventive maintenance or repair.

2.1 Accessing the UPS terminals

The following operations must be performed while the UPS 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 UPS is completely isolated from all power sources: battery and AC power line. In particular, check that:

- UPS input line is completely isolated;

- Batt er y circuit breaker/disconnect is open;

- All UPS power and load connection switches (SW IN, SWBY, SWOUT and SWMB) 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 UPS 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 UPS can supply only Delta load.

• The output neutral must not be connected unless the UPS 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 UPS 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 DC input requires a disconnect means which is provided in most Staco supplied battery cabinets. AC and DC cables and cable lugs are to be provided by others as part of the UPS installation

Page | 5

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. If the load requires a neutral connection (i.e. wye), then an input neutral must be provided. Refer to the Power Connection terminals diagrams later in this section for details concerning configuration of the neutral to ground bond.

2.2 UPS - Single Module Configuration

The UPS is designed to work as Single input Unit or as Dual input Unit.

Figure 3 – Single Input 1-Line

Figure 4 - Dual Input 1-Line

Page | 6

2.3 Cable Entry

The cables can enter in the UPS from the bottom or from the top with the optional (Top Entry Cabinet) Proceed as follows in order to open the UPS

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 UPS terminals in base to your configuration (see Figure 5 and Figure 6)

2.4 Connect of Power Cables

2.4.1 Input Line without Neutral

If utility is a 3-wire source and the load requires a neutral, a transformer must be inserted either on the mains supply line or on the bypass line.

Figure 7 - Schematic diagram: Single Input without Source Neutral

Figure 8 - Schematic diagram: Dual Input without Source Neutral

Page | 9

2.4.2 Single Input

Connect the input, output and battery cables to the terminals as shown in Figure 9 and Figure 10:

Figure 9 – FLU UPS Single Input 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 single input is a factory default configuration. Do not remove the bypass jumper. The input phase connections are made using bolts to one of the three holes in the busbar. Do not loosen the bolts that attach the busbar.

The UPS 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.

Page | 10

Figure 10 – FLU-T UPS Single Input Power Connection Terminals

Once installation has been completed inside the equipment, put the switch cover panel back and close the door.

Page | 11

2.4.3 Connection of Power Cables for Dual input Unit

Connect the input, bypass, out put and battery cables to the terminals as shown in Figure 11 and Figure 12

Figure 11 – FLU UPS Dual Input Power Connection Terminals

The single input is a factory default configuration. Remove the jumpers present between the SWIN and SWBY. The input phase connections attach using bolts through the holes that were previously used to attach the busbars. The main (rectifier) input is located on the left and the bypass input is on the right. The neutral input comes from the bypass source; no neutral is to run to the rectifier input source, although the rectifier source must be a grounded wye.

For the Input, Bypass, 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.

Once installation has been completed inside the equipment, put the switch cover panel back and close the door.

2.5 Differential (GFI)

UPS

a - EPO terminal board located on the UPS b - EPO switch (not provided).

If the UPS 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 cur r ent pulses

• Delay greater than or equal to 0.1 s.

In the standard version without an isolation transformer on the bypass line, the neutral from the mains power supply is connected to the output neutral of the UPS.

THE ELECTRICAL SYSTEMS UPSTREAM AND DO WNSTREAM OF THE UPS MUST BE EXACTLY THE SAME (DELTA-DELTA or WYE-WYE)

When operating in the presence of mains supply, a differential breaker (GFI) insta l led on the input will intervene as the output circuit is not isolated from the input cir cuit. When operating without mains supply (from battery) the input differenti al 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 UPS possibly coordinated with those on the input.

2.6 Emergency Power off Device (EPO)

The UPS has an EPO (Emergency Power Off) function. In the event of an em er gency, using this function will cause the UPS to shut down the rectifier, inverter, and static switch and completely disconnect the power to the load. The Output circuit of the UPS should not be considered safe, unless the UPS is Off and the input power source to the UPS has been removed by opening the input disconnect devices which are external to the UPS, 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 UPS shuts down. On the UPS, 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.
