Manual de Instalação e Operação
3.2.4. VOLTAGE SENSORS CONNECTOR
In this connector of 11 terminals it is made the connection of the voltage sensoring
inputs, being a pair for each voltage sensor.
Usually, this connection is made through voltage transformers (PT’s). If there is not PT
the connection should be made directly. Respecting the maximum limit of 500 Vca.
IMPORTANT:
The voltage between phases, in this connector, should not
surpass 500Vca.
4. INSTALLATION
Before installing the Smart Cap 485, certify yourself that all the requisites for its
installation are attended.
- Type of connection to be used;
- Necessaries PT’s or CT’s;
- Adequates capacitors bank;
- Phases of the electric system correctly identified, electric facilities and earthing of the
system in perfect conditions.
The
Smart Cap 485
should be installed in a box or panel that has complete sealing
against dust and water sprinkles. This box or panel also should protect it against mechanical
shocks, vibrations and high temperatures.
4.1. FEEDING
The feeding input connector allows the connection with a voltage from 90 to 270Vca the
frequency from 45 to 65Hz. This connection is only for equipment feeding. The equipment
earthing also is done in this connector.
The
Smart Cap 485
does not have a button “POWER ON”, it is connected at the
moment in which it is fed.
Avoid connecting the contactors activating coils on the same feeding phase, this avoids
interferences on the equipment circuit.
