AR (automatic reclosing) interval is the time after which the protected equipment will turn on after the
occurrence of "Voltage failure".
Umax is the maximum voltage operation threshold.
Umin is the minimum voltage operation threshold.
1. SERVICE
1.1. Device service
RN-122 is designed to protect household appliances (equipment) up to 3.6 kW (refrigerators, air conditioners,
washing machines, TV and audio equipment, etc.) against unacceptable mains voltage fluctuations and the
consequences of neutral interruption.
RN-122:
–provides disconnection of the protected equipment if the value of the mains voltage exceeds the limits set by
the user (after the mains parameters are restored, the automatic reclosing will take place (hereinafter referred to as
the “AR” - automatic reclosing);
–indicates the value of the mains voltage and the presence of voltage in the device socket.
1.2. Controls and overall dimensions of RN-122
Controls and overall dimensions of RN-122 are shown in Fig. 1.
1–ON LED is on when there is voltage
in the socket of the device;
2 - Button of changing the maximum
voltage operation threshold and
increasing the value when setting
parameters;
