2.2.1.4 Novar 1005D / 1007D Controllers
The power supply is connected to terminals 16 (
L1
) and 18 (
N
). Power supply voltage needs to be
externally protected ( see chapter
Protection
below ).
Despite of 1005 / 1007 models, power supply terminal
is not
internally connected to the common pole
of output relays.

2.2.1.5 Protection
Article 6.12.2.1 in the EN 61010-1 standard requires that instrument must have a disconnecting device
in the power supply circuit (a switch — see installation diagram). 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-isolated 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).
