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.
VDE O126-1-1
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.
CEI 0-21
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.

Warnings
Be aware that the relay outputs can change state during and after the unit
setting (before the unit is used again ensure that the proper setting is done)!!!
Be aware that the devices connected to binary outputs of the unit may operate
upon disconnection of power supply, measurement inputs and/or binary
inputs!!!
If the device is used in other way then stated by the manufacturer, the
protection provided by the device may be corrupted.
!!! CAUTION !!!
Dangerous voltage
In no case touch the terminals of voltage measurement!
Adjust set points
All setpoints are pre-adjusted to their typical values. Before putting into operation, the setpoints must
be checked and/or adjusted to the required values.
Installation may be done by qualified personnel only.
To avoid personal injury do not perform any action not specified in this guide!!!

Wiring
“Star” connection
If used for rated voltage 230 VAC ph-ground, set the setpoint Basic: Uin is to 230/400V, for systems
with rated voltage 120VAC ph-ground, set the setpoint Basic: Uin is to 120V. No additional setting is
necessary for indication of “Star” connection - MainsPro provides automatic detection of phase-ground
voltage measurement. MainsPro provides over-range to 130% of the rated voltage, i.e. 300 VAC for
230 V system and 156 V for 120 V system with no change of measurement accuracy.

“Delta” connection
In this arrangement, MainsPro is rated for 400 VAC ph-ph with over-range to 130% = 520 VAC with no
change of measurement accuracy. Setpoint Basic: Uin is to be set to 230/400V, no additional setting is
necessary for indication of “Delta” connection. MainsPro provides automatic detection of phase-phase
voltage measurement.

Connection with voltage transformers
MainsPro allows connecting HV or other measurement transformers with secondary rated voltage
100V. Provide the "Star" or "Delta" arrangement on the primary windings of the transformers and
connect the secondary 100 V to the MainsPro measurement inputs. Setpoint Basic: Uin is to be set to
120V. This setting provides the guaranteed measurement accuracy for the 100V inputs with over-
range to 120V * 130% = 156 VAC.
Note:
It is recommended to use “Delta” arrangement on the HV side to avoid nuisance tripping caused by
phase voltage unbalance.
Single-phase connection
MainsPro provides support for single-phase applications. Use the UAterminals to connect the
measured voltage to the unit and set the setpoint Basic: System to 1ph. Use the same setting of rated
voltage selection as mentioned above.
