6 INSTALLATION & COMMISSIONING
DANGER DO NOT CONNECT IN PARALLEL TO EACH OTHER TWO OR MORE VOLTAGE STABILISERS OUTPUT LINES.
6.1 SITE CHOICE
The installation site must comply with the basic requirements listed below:
unless otherwise agreed upon, the ambient temperature must fall in the -25/+45°C range
unless otherwise agreed upon, the maximum installation altitude is 1000mt a.s.l.
the floor or surface must be flat and able to withstand the unit’s weight;
the installation room dimensions and the airing system must ensure that the generated heat can be disposed of.
Otherwise, a cooling systems must be arranged;
the lighting system must be suitable for normal operating and maintenance routines;
the ground circuit must comply with the relevant applicable rules and regulations;
If not previously arranged during the contracting phases, the unit must not be commissioned in case of:
corrosive, explosive or flammable atmosphere;
presence of conductive dust in the environment;
proximity to radiation sources;
possibility of floods.
Avoid direct heat and contact with liquid, flammable or corrosive materials.
Do not clog the cabinet air outlets and leave 150-200mm clearance to allow for the air to circulate.
Check that anti fire devices are available in the area.
6.2 ELECTRICAL CONNECTION
DANGER THE VOLTAGE STABILISER IS NOT AND MUST NOT BE USED AS A PROTECTING DEVICE FOR NEITHER THE PLANT
NOR THE LOADS. THE ELECTRICAL CONNECTION MUST BE CARRIED OUT BY TRAINED AND QUALIFIED PERSONNEL, AWARE OF
THE INVOLVED RISKS. ALWAYS USE SUITABLE TOOLS AND PERSONAL PROTECTIVE EQUIPMENT (PPE). THE OPERATIONS
MUST BE CARRIED OUT IN CONFORMITY WITH THE RULES AND REGULATIONS ENFORCED IN THE COUNTRY OF INSTALLATION.
6.2.1 Supply
The supplying line must comply with the nameplate technical data. The unit is not protected against short-circuit or
overload. In compliance with the safety regulations in force, the installation should take place in a system fitted with:
an interrupting device with capacity referred to the maximum input current upstream the unit
an interrupting device with capacity referred to the output current downstream the unit
The above mentioned circuit breakers are not included in the standard unit, but they can be provided as optional
accessories.
Note The installation of a co-ordinated upstream and/or downstream differential circuit breaker may be done under the
site manager’s responsibility. Said differential circuit breakers are not included in the unit
Note If the load supply continuity is of paramount importance, it is advisable to install a by-pass circuit to allow the load
to be fed directly from the mains in case the unit is switched off for maintenance or internal failure.
Note If the load is thought to be sensitive to voltages outside the rated tolerance, the addition of an over/undervoltage
protection system able to disconnect the load in said conditions is strongly recommended.
6.2.2 Connections
Note The cross-section value of the cables/bars for the connection to mains and load falls entirely under the installer’s
responsibility. The Manufacturer shall not be held liable for any damage that might occur to people or belongings due to an
incorrect choice.
Open the cubicle and locate main parts and connection points. Remove the accidental contact protections. Prepare the
connection cables/bars with regard to the current values and make them go through the openings prepared on purpose.
The very first operation is to connect the earth wire to the terminal identified by PE, GRD or G.
DANGER THE EARTH CONDUCTOR MUST NEVER BE ELECTRICALLY INTERRUPTED NEITHER INSIDE NOR OUTSIDE THE
UNIT.
The earth wire cross-section must be chosen in conformity to the regulations in force. Therefore, depending on the phase
cable cross-section, the earth wire cross-section should respect the values in the table below:
PHASE CABLE CROSS-SECTION S [sqmm] EARTH WIRE MIN CROSS-SECTION [sqmm]
S ≤ 16 S
16 < S ≤ 35 16
35 < S ≤ 400 S/2
400 < S ≤ 800 200
S > 800 S/4
Note If a not standardised cross-section is found when applying this data, choose the nearest larger one.
WARNING FOR THE CORRECT OPERATION OF A THREE-PHASE VOLTAGE STABILISER, THE NEUTRAL WIRE MUST BE
AVAILABLE AND CONNECTED TO THE RELEVANT TERMINALS.
Connect the unit to mains and load, trying to avoid kinks and accidental contact between the cables and the electric
components. Make the connections respecting the indications written on the terminations.
WARNING WHEN THE STABILISER IS PROVIDED WITH TWO POSSIBLE FUNCTION MODES (DOUBLE INPUT VOLTAGE
VARIATION RANGE), IT IS NECESSARY TO COMPLY WITH THE INDICATIONS ON THE TERMINALS. CHANGING THE INPUT
