Many thanks for choosing our product in order to protect your equipment

STS automatic static transfer switch (STS), is a device that enables automatic or

manual transfer between two AC power supply sources, ensuring a transfer time of less

than ¼ of a cycle.

The use of STS static transfer switches within an electrical distribution system

provides a means of secure protection against any potential disruption of the power supply,

due to interruptions of the supply source or failure of the distribution lines caused by

environmental phenomena or human error.

The STS series is available in 100-150-200-250-300-400-600-800-1000 Ampere models;

The range is available in three or four pole formats for either three-phase or three-phase plus

neutral switching installations.

The STS provides a guaranteed means of switching between two alternative and

independent power sources thus ensuring a continued supply of power to any critical load.

The switching can either be AUTOMATIC should the incoming supply fall outside the

predefined window of operation (user-defined), or MANUAL should an operator want to

force switching between the two input supply sources from the mimic display panel or via a

remote connection.

ATTENTION

This manual contains instructions for the installation, start up and use of the product.

Read the manual carefully before installing the product.

The manual contains important information with regards to use of the device; therefore it must be read

carefully and should be consulted before activating the STS.

All the installation and maintenance operations inside the device must be conducted exclusively by trained

personnel.

Do not insert any objects in the ventilation slots or in any other openings.

To reduce the risk of electric shock, install the device in sites with controlled ambient temperature and relative

humidity, free of open flames and corrosive substances.

The device has two power input lines. Even if only one of the sources is active, the voltage level inside the

system is dangerous.

When the device is in manual BY-PASS status, the voltage level inside the system is dangerous.

SAFETY REGULATIONS

Always ensure that the ground connection is the first connection to be made during the installation of the

system, this terminal is identified by the following symbol:

THE STS MUST NOT BE OPERATED WITHOUT A GROUND CONNECTION.

The STS must only be operated with all external and internal panels fastened as specified and with the front

door closed.

Do not perform any maintenance activities inside the STS even if only one power source is connected to it.

For maintenance, close either the SW4-1 or SW4-2 by-pass switch and then open all of the other switches.

Always use a multimeter to check that no dangerous voltages are present inside.

STORAGE

If the STS is not to be installed immediately, it must be stored in its original packing and be shielded from

humidity and bad weather. The storage room must have the following characteristics:

Temperature:

Relative humidity

-10° ÷ +50°C

90% max

INSTALLATION ENVIRONMENT

Follow these recommendations when choosing the installation environment:

- avoid dusty areas

- confirm that the floor can support the weight of the STS

- avoid rooms that are too small and would prevent normal maintenance operations

- relative humidity at 20°C must not be greater than 90° non-condensing

- avoid placing the device in a position exposed to direct sunlight or hot air

- verify that the ambient temperature, with the STS in operation, is less than:

operating temperature:

maximum temperature for 8 hours/day:

average temperature over 24 hours:

0 ÷ +40°C

+ 40°C

+ 35°C

In order to maintain the temperature of the operating environment as specified above, it may be necessary to

install a means of removing the heat dissipated by the STS.

PRELIMINARY OPERATIONS

PACKING CASE CHECK

When the STS is delivered confirm that the packing case has not been damaged during transportation.

Be careful when removing the packing case to avoid scratching the STS cabinet.

The device must be handled carefully: any knocks or falls may damage it.

CONTENTS CHECK

The following item must be included inside the packing case.

• Operating Manual

• Test report

• STS MANAGER software, CD-ROM with the Software for remote STS management

" STS Manager Software"

• CC05 Cable

POSITIONING

The air used to cool the STS is drawn in through the grills located on the lower part of the front door and exits

through the fan grills located on the top.

When positioning the STS keep in mind that:

• the space in front of the device should be free of obstacles for a distance of at least one metre to

permit maintenance operations

• in the back part of the device should be a free space of at least 50 cm between the rear of the device

and the wall to permit maintenance operations

• there should be a free space of at least 60 cm between the top of the device and the ceiling to permit

proper dissipation of exhaust air from the fans

Cable entry is positioned at the bottom of the STS through an opening in the cabinet base.

It is also possible to install the input and output cables from above by locating the cables in a vertical channel.

The power and communications cables must all be connected from the front of the cabinet.
