The power demand is the same as those of standard version. The supply voltage connects to terminals 3 (L1) and 5 (L2/N). In case of DC supply voltage the polarity of connection is generally free, but for maximum electromagnetic compatibility grounded pole should be connected to the terminal 5 (L2/N); see connection examples below. Power supply voltage need to be externally protected ( see following chapter). Despite of standard version, power supply terminal 3 (L) is not internally connected to the common pole of output relays. Terminals 4 and 6 are not used.

In case of DC supply voltage the polarity of connection is free. Power supply voltage need to be externally protected ( see chapter Protection below ). Power supply terminal 4 ( L1 ) is internally connected to the common pole of output relays. It is necessary to dimension the power supply protection in consideration of output contactors’ power as well. 16

It must be located at the instrument’s immediate proximity and easily accessible by the operator. The disconnecting device must be marked as such. A circuit breaker for nominal current of 10 amp makes a suitable disconnecting device, its function and working positions, however, must be clearly marked (symbols ―0‖ for power off and ―I‖ for power on in accordance with EN 61010–1). Since the controller’s inbuilt power supply is of pulse design, it draws momentary peak current on powerup which is in order of magnitude of amperes. This fact needs to be kept in mind when selecting the primary protection devices. 2.2.2 Measurement Voltage 2.2.2.1 11xx and 10xx Line Controllers The power supply voltage is used as measurement voltage in 11xx line controllers and it is not thus necessary (or possible) to connect measurement voltage independently. 2.2.2.2 12xx Line Controllers The 12xx Line Controllers feature a general-purpose, galvanic-insulated voltage measurement input. It allows to connect measurement voltage in the range from 45 to 760 V AC at the frequency range 43 to 67 Hz of either phase or line voltage. In basic connection phase L1 goes to terminal L (7) and neutral wire to terminal N/L (9). The measurement voltage must be protected externally. If the measurement voltage is identical with power supply voltage, they can share a circuit breaker. Otherwise each voltage branch must be protected with fuses or circuit breakers of nominal value 1 to 6 A. If the measurement voltage is connected via a metering voltage transformer, you have to enter the transformer turns ratio in instrument setup (parameter 17 – see further below) for correct expression of measurement values displayed. 2.2.3 Measurement Current Metering current transformer (CT) outputs connect to terminals 1 (k) and 2 (l). At 10xx line controllers, connection polarity is opposite : terminal 1 is l and terminal 2 is k. A metering current transformer of nominal output current 5 or 1 A can be used – the metering current transformer’s ratio must be entered when setting up the instrument for proper measured values display (parameters 12, 13 – see further below). At NOVAR-11xx models, the connector features a screw lock to prevent accidental pull-out. 17
