Connection type of auxiliary supply, voltage measurement input and current measurement input must be 3 phase-neutral. Device
must be operated after finishing of the 3-phase connections.
After the device has energized, it finds connection errors and corrects automatically.
Phase current should not be aqual to zero in order to let the device to sense the connection error. Device sense the connection error
according to Active Power direction.
Device switching ON and OFF the 1st steps 3-phase capacitor during the correction of connection errors (Phase sequence error and
polarity error of Current Transformer). Device may not correct the connection errors if there are too many instant variations for loads and
nonlinear loads (Such as Thyristor or triac controlled frequency inverter, UPS etc.). In this case, user should disconnect the device and restart
it to making the same operation.
This operation also can be operated as turning ON the Auto SET function in Auto menu. In this case device corrects the errors and
then calculates the capacitor values.
After connection errors are corrected; capacitor steps are calculated with turning ON the Auto Setup function in Auto menu (Refer to
Automatic Capacitor Recognition menu).
It is an obligation to connect a 3-phase capacitor for 1st step. All steps are measured seperately if the program-10 (PS-10) is selected
in Program menu. In this program (PS-10); single or 3-Phase capacitors can be connected according to requirements of the system in
any sequence.In case of choosing one of the other programs, device measures the 1st steps power value and then calculates the other steps
respectly to this value. Device calculates the capacitor values which will be switched ON according to selected program; device switches
ON / OFF the required steps.
Connection of circuit breaker or automatic fuse is highly recommended between the network and RM-12P. Circuit breaker must be
in close proximity to the device.
All used fuses must be FF type and the current values of the fuses must be 2A or 3A and 6A (Refer to Connection Diagram).
Generator input must be activated only when the network is supplied by the generator. Otherwise device will be switched to the generator
position for every kind of generator starts including the maintaining purposes.
In order make a correct measurement, J type (Fe/Cu-Ni) thermocouple must be connected to TEMP terminal.
