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.

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.

Power supply

MainsPro provides set of 3 terminals for the purpose of dual power supply range:

8 - 40 VDC: use the terminals + and N/-

85 - 265 VAC / 110-370 VDC: use the terminals L/+and N/-
