Preliminary operations
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 reason for this is as follows: The UPS is supplied with the paralleling controls as standard,
but the UPS is shipped with this feature disabled. Disablement is due to one end of a flat cable being left
unconnected. One end of this cable connects to J2 of the System Card (a printed wiring board assembly with
"2032" in the part number). The end that is left unconnected needs to be connected to J3 on the paralleling Card
("2034" in the part number) if parallel operation is desired. If this cable is connected, the UPS will not operate
without the modular cables connected between the UPS units that are to be paralleled. That is, DO NOT connect
this cable for standalone (non-parallel) operation.
Storage
In the following situations:
- installation not immediately after delivery;
- de-installation and storage while awaiting relocation,
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.
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. As a general rule, the packaging
should include the following: this manual, the installation drawing, the warranty and eventual accessories.
Handling
The equipment must only be handled by adequately trained personnel. It can be unloaded from the vehicle and put
into place by lifting the box or the wooden deck to which the equipment is secured with a fork-lift truck. A fork-lift
truck should be used for the permanent positioning of the equipment, in accordance with the instructions provided
below.
1Insert 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.
2Secure the device to the fork-lift before moving it.

Pag. 12 a 83 0MLMHTK65RUENUB
Risk of overturning
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.
Installation environment
The UPS and the battery cabinet have been designed for indoor installation. The choice of premises for installation
should comply with the points set out below.
Ambient conditions:
ensure that the floor can support the weight of the FIRSTLINE and of any battery cabinet that may be
used
avoid dusty environments (the indoor area must be free of conductive contaminations)
avoid narrow environments that could hinder normal maintenance operations
avoid placing the device in areas exposed to direct sunlight or heat
ensure that the ambient temperature conforms to the following:
- minimum operating temperature: +32°F ( 0 °C)
- maximum temperature for 8 hours a day: +104°F (+ 40°C)
- average temperature for 24 hours: +95°F (+ 35°C)
Dimensions of the premises
For the mechanical dimensions of the cabinets, refer to the “INSTALLATION DRAWINGS” supplied with the
UPS and with the battery cabinet, if present. These drawings provide the following data:
the position of the holes in the base to secure the device to the floor, if applicable;
a view of the floor support for the sizing of a structure to raise the cabinet, if applicable;
the position of cable entry;
the position of the fans on the top of the UPS, for the positioning of a structure to convey the warm air
discharged by the equipment outside the premises, if applicable;
the input, output and battery cables section;
the power dissipated by the equipment (kW).

Pag. 13 a 83 0MLMHTK65RUENUB
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.
A heat dissipation system is required to keep the temperature of the
premises housing the equipment within the field 20-25°C.
The heat dissipation needed for the correct operation of the UPS is
brought about by the air current made 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, and therefore the correct
operation of the UPS, 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.
Air change for battery premises
The premises housing the battery cabinet must have sufficient air circulation to ensure that the concentration of
hydrogen issued during battery charging is kept below the danger limit.
The air change in the premises should preferably be provided by natural ventilation, otherwise by forced ventilation.
The standard EN 50272-2 for air change envisages that the minimum opening must satisfy the following equation:
A = 28 x Q = 28 x 0.05 x n x Igas x C10 (1/10³) [cm²]
where: A = free opening for air intake and outlet
Q = flow of air to be removed [m³/h]
n = number of battery elements;
C10 = battery capacity over 10 hours [Ah]
Igas = current that produces gas [mA//Ah]
In accordance with the standard: Igas = 1 VRLA type battery (*)
(*) for vented or nickel batteries, contact the battery manufacturer.
When the equation is applied for 240 element (40 battery) hermetically-sealed lead batteries:
A = 336 x C10 / 10³ [cm²]
When using 120Ah batteries, the minimum aperture should be approximately:
A = 41 [cm²] or (multiplied by .155) = 6.36 in2
The air intake and outlet must be positioned to ensure the best possible circulation; for example:
- apertures on opposite walls,
- a minimum distance of 6 ft. when they are on the same wall.

Pag. 14 a 83 0MLMHTK65RUENUB
Electrical Connections
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:
- the UPS input line is completely isolated;
- that the battery circuit breaker/disconnect is open;
- all the UPS power and load connection switches (SWIN, 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 labelled PE. The UPS must operate with the grounding system
connected.
Do not connect the output neutral to the input neutral.
CAUTION: 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.
CAUTION: If a three-phase non-linear load is connected to the output, the current on the
neutral conductor can reach a value of 1.5 times the value of the phase current, dimension
the input/output neutral cable appropriately.
CAUTION: The UPS cannot feed from a corner ground or mid-point grounded delta supply
source.
CAUTION: Use only lugs or cables with tin-plated eyes for the connections.
CAUTION: Ensure correct phase sequence at the input and output terminals
Ensure correct polarity battery connections
The DC input requires a disconnect means which is provided in each RPS supplied battery
cabinet ordered with this unit. Battery cabinet models are BBX 1900 480V UL L6
3U BBX 1900 480V UL L8 3U
AC and DC cables and cable lugs are to be provided by others as part of the UPS installation
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.

and the bypass input is on the right. The neutral input comes from the bypass source; no neutral is to run from the
rectifier input source, although the rectifier source must be a grounded wye.
Note: For the Input, Output and Battery connections, respect 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.
Bond: The UPS is provided with a separate bus bar 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 bus bar must be removed.
Once installation has been completed inside the equipment, replace the switch cover panel and close the door.
