MainsPro Installation and Operation Guide
Introduction
Congratulations to your purchase of ComAp MainsPro unit! MainsPro is a microprocessor-based
protective relay, providing a comprehensive set of protective and supplementary functionalities. The
basic protective functions are:
Voltage
Frequency
Loss of mains
This covers the basic requirements for mains-decoupling (inter-tie, „G59/2“) protection, but allows also
usage in many applications where benefits of the unit’s unique functionality is needed.
Purpose of this manual
The Installation and Operation Guide serves for the personnel, providing installation of the MainsPro
unit. It contains wiring and setting instructions, needed for service and commissioning of the unit. It
also contains introduction of the user interface and necessary procedures to perform setting and
operating of the unit. Though MainsPro is very simple and intuitive for the operating personnel, we
recommend keeping one copy of this manual available permanently at the installation site, where
MainsPro unit is installed, to facilitate the necessary service and operation tasks.
Conformity declaration
Following described machine complies with the appropriate basic safety and health
requirement of the EC Low Voltage Directive No: 73/23 / EEC and EC
Electromagnetic Compatibility Directive 89/336 / EEC based on its design and type,
as brought into circulation by us.
The unit is certified to comply to the appropriate requirements of the
standard DIN V VDE V 0126-1-1 (certificate ref. 44 207 11 398020,
available upon request), with the following conditions:
The conformity with the Standard DIN V VDE V 0126-1-1,
chapter 4.1/ 6.1, which is declared in the certificate 44 207 11
398020, requires the tolerance against one fault. In order to
fulfill this functional safety requirement, a redundant
architecture has to be built by the usage of two certified units.
It has to be ensured that each of both units is connected to an
output (relay) which is capable to induce opening of the
operated contactor.
The unit is certified to comply with the requirements of the standard
CEI 0-21. The product MainsPro CEI 0-21 is set by default to cover
the functionalities and default limits requested by this certification. In
line with this certification, the output !CommTrpPer, set by default on
the RE1 output of the unit, is to be used for opening the circuit
breaker in the connection point between generator and the mains.
