1 INTRODUCTION AND SAFETY RECOMMENDATIONS
CIRCUTOR S.A. would like to thank you for showing your trust by choosing one of our Computer MAX
series regulators. These units are constructed with the latest state-of-the-art technology, including a
powerful processor to calculate the optimum algorithms for achieving the best compensation of cosφ.
The units comply with the Electrical Safety Standard EN 61010, in accordance with the requirements of
the Low Voltage Directive (LVD) 73/23/EC and EMC Directive (2004/108/EC) and, therefore, they are
certified to carry the CE mark.
This user manual describes the operation of the
Computer MAX series regulators and shows the user
the procedures required to install, commission and operate the units.
SAFETY
CAUTION!
The installation and maintenance of the unit must be performed by duly trained and
authorised staff and in accordance with the national and international standards. Any
inappropriate manipulation or use of this equipment out of the conditions specified by the
manufacturer may involve serious dangers to the user.
DANGER!
Before performing any maintenance operation on the Computer and associated PF
compensation equipment, be sure to disconnect the main switch. After disconnecting the
switch, wait at least 5 minutes to ensure that the capacitors are totally discharged.
During the installation, maintenance or commissioning of equipment regulated by a Computer
MAX
unit, the following safety precautions must be observed:
 Before connecting the equipment make sure that the earth terminals have been properly connected.
A defective earth connection may cause a wrong operation of equipment and involves a danger of
electric shock to the user or system operator.
 Maintenance must be performed taking the necessary precautions to avoid electrocution and electric
shock. Ensure that the unit has been disconnected and wait the necessary time to ensure that the
capacitors are totally discharged before any maintenance action. We recommend the use of safety
goggles and gloves when cabinet doors are open and protection covers removed.
 If a PF compensation unit is connected to mains and capacitors are accidentally connected without
load, a resonance may occur. In such condition voltage harmonics may be amplified, cause
overvoltage and damage the compensation unit and other equipment connected to the mains.
 The start-up and interruption procedures indicated in the manual must be followed to avoid
damaging the PF equipment and/or other equipment connected to mains.
 The adjustment or replacement of components or parts of the unit must be made with original
replacement parts and in accordance with the procedures described in the corresponding instruction
manual.
1.1 Delivery spot check
After unpacking the equipment check the following points:
 Check that equipment has not suffered any damage during transport.
 The equipment corresponds to type you ordered. (See label at the rear face, fig. 1.1)
 Check that the characteristics in the label are suitable for the site where the regulator has to be
installed. (Supply voltage and frequency, measuring range, etc.)
 Follow the instructions in section 3 for installation and set-up.
 If you may observe any anomaly during the installation or set-up, contact with CIRCUTOR,
technical service.
