SAFETY RULES !
This appliance has been designed to give excellent performance provided it is installed and used carefully in
a suitable electric environment by qualified personnel.
The following rules
must be obeyed
when installing the regulator :
•
Follow the instructions in this manual exactly and observe all safety measures in force.
•
Do NOT tamper with or disassemble the regulator's internal components; doing so will
INVALIDATE THE GUARANTEE and may cause unnecessary damage.
•
The regulator does not contain components that can be repaired by the user.
•
The regulator must be suitably and effectively earthed by the installer according to the standards in force;
earthing is essential for the EMC filter to operate correctly.
•
The user must be protected from the electric supply and the motor must be protected from possible
overloads in compliance with the standards in force.
•
DO NOT
supply the regulator without the internal protection panel made from lexan.
•
DO NOT
touch the electrical parts of the circuit when the power supply is connected under any
circumstances.
•
Before supplying power to the unit, check carefully that the power and earth are correctly connected.
•
If the mains supply is "disturbed", which may be due to other electrical power components causing
irregularities in the supply (power contactors), it is recommended that supplementary three phase
‘
SURGE ARRESTER
’
filters are installed directly on the regulator supply.
•
Avoid repeatedly connecting and disconnecting the power supply to the regulator; a constant supply
keeps the regulator at working temperature and eliminates problems caused by condensate inside the
protection case.
•
Alternatively, use the remote terminal board contact 'MB' S2 = ON/OFF.
•
The S2 = ON/OFF contact on the MB terminal board does not cut the mains supply and therefore cannot
be used as a safety switch.
•
Install the regulator out of direct sunlight so that the container cannot get overheated and cause a
reduction in the maximum load current.
•
The appliance may operate at environmental temperatures up to 50°C. Do not install it where this
temperature may be exceeded or the integrity of the regulator will be compromised and the appliance
may make the user appliance operate at full load (100%) with all consequent effects.
•
The appliance must be stood vertically to encourage heat dissipation and to ensure there is a sufficient air
circulation and free space measuring
150 mm
above and below the regulator. If several regulators are to
be grouped together on a single electric board, provide forced air circulation with a fan or cooling unit of
sufficient power.
•
Use the holes on the lower and power terminal board sides of the appliance, for entrance of the
connection cables. This will prevent water, dust etc. from getting in and will ensure the
IP55
protection
level is maintained using adequately sized cables and sheaths of suitable quality.
•
Reassemble and check the cover of the external protection panel is properly closed.
•
DO NOT alter or damage the identification stickers on the equipment.
•
DO NOT force the trimmers to rotate beyond their set mechanical travel.
•
Only alter the trimmers intended for regulation.
•
Under no circumstances alter the trimmers marked with the spot of red paint.
WARNING !
HIGH LEAKAGE CURRENT: first connect to earth !
