• The voltage stabilisers and line conditioners should be considered as transformers or distribution lines from
the point of view of the installation and of the electrical safety. This equipment is “transparent” to the input
voltage.
• The Neutral input of the three phase equipment should be necessarily connected to the terminal intended for
this purpose.
• The phase to phase voltage at the output may not be the same on the three phase voltage stabiliser and line
conditioners with independent phase regulation with unbalanced voltage from the three phase input supply on
the loads, however the phase to neutral regulation will be kept.
• The line conditioners (voltage stabilisers fitted with galvanic isolation transformer) can be connected with the
desired neutral condition. The wire bridge going from one output terminal (neutral) to the ground terminal can
be deleted for the isolated neutral condition.
• The servo-motor voltage stabilisers and line conditioner incorporate mechanical components (gearing, dented
belts, etc.) Do not service inside the equipment as the motion during the regulation may cause personal
injuries.
• Devises mounted on CHASSIS or RACKS for the installation on pre-determined assembly units is intended to
be done by professionals.
-
Your installation should be planned and carried out by qualified personnel, who will be responsible for
applying the safety and EMC legislation as well as standards regulating the specific installation where
the product is to be used.
-
CHASSIS mounted equipment has neither enveloping protection nor connecting terminals.
-
RACK mounted equipment has no connecting terminal protection.

SAFETY INTERACTIONS FOR BATTERY EQUIPPED PRODUCTS.
• The UPS, SPS and FAC are continuous supply equipment. If the mains supply fails while the equipment is
operating, the output lines will continue supplying output voltage depending on the autonomy provided by the
battery.
• Generally the batteries are delivered already fitted in a single cabinet except in specific situations where, for
various reasons, they are delivered inside a separate enclosure.
• For proper operation the battery cabinet must be located beside the machine.
• The battery supply can involve the risk of electric shock and can produce high short circuit current. Observe
the following preventive measures before handling any terminal block identified in the labelling as “Battery”.
-
Disconnect the corresponding protection components.
-
When connecting a battery cabinet to the equipment abide by the cable polarity and colour (red-
positive; black-negative) indicated in the manual and by the corresponding labelling.
-
Wear rubber gloves and shoes.
-
Use tools with insulted handles.
-
Remove watches, rings or other metal objects.
-
Do not place metal tools or objects on the batteries.
-
Never touch with your hands or through conducting objects, do not short the battery terminal block or
the battery enclosure.
• To prevent full battery discharge and as a safety measure after an extended power failure, as well as at the
end of the daily work, you should turn off the loads and later the equipment according to the operation given in
the “Operating Manual”.
• For extended periods of disconnection connect the equipment every month for at least 10 hours to charge the
battery, to prevent any irreversible deterioration. When storing the equipment, place it in a cool and dry
location, never outdoors.
• For installation with supplementary machines or an independent Bypass line, only a single differential of 300 -
500 mA will be placed in common for both lines, at the head of the installation.
