The device must operate in the power network protected by an
automatic circuit breaker with the interrupting current not more
than 16 А.
The device is not designed for power-cut while short-circuited.
Attention
1. PRECAUTIONS
•Before using the device, please carefully read the following User’s Manual and
save it for the whole operation period.
•Before connecting the device to the power supply network, keep it within two
hours in operating conditions.
•Do not use abrasive materials or organic compounds (alcohol, petrol, sol-
vents etc.) to clean the device.
•It is prohibited to open and repair the device on your own.
•It is prohibited to open and repair any protected equipment, if it is connected
to the device socket.
•It is prohibited to use the device with mechanical damages of its case.
•It is prohibited to use the device in high humidity conditions.
•Avoid ingress of water into the device.

3. APPLICATION
VR-101F voltage relay is designed to protect household appliances (refrige-
rators, washing machines, PCs, video and audio equipment, etc.) connected to
it against inadmissible voltage fluctuations in the power supply network.
4. FEATURES
•Protection of household appliances against voltage swings
•Restarting delay for connected equipment protection
•Fixed protection parameters for operation simplicity
•Voltage relay status indication
•Protective shutters and grounding contacts for safe operation
•Shockproof flame-retardant case
5. TECHNICAL DESCRIPTION
VR-101F voltage relay presents a device with an electronic circuit with micro-
processor control assembled in the case with a wall plug and socket. VR-101F
voltage relay has fixed settings and does not need additional programming.
VR-101F voltage relay disconnects the power supply to electrical appliances
connected to it, if the power supply voltage exceeds specified values and it
automatically recovers the power supply within the specified time after voltage
normalization, in such a manner, it protects the appliances connected to the
power supply network against voltage swings dangerous for them. At that, indi-
cators of VR-101F display the voltage relay status.

6. CONNECTION
VR-101F voltage relay is connected to a standard socket of 230 V / 50 Hz power
supply network. The socket must be rated at the current 16 A. The power supply
line of the socket must be protected by an automatic circuit breaker with current
not more than 16 A to protect against short circuit and overload. The circuit
breaker must be located in an electric service cabinet. Protected devices are
connected to the output socket of VR-101F. The long consumption current of
devices being connected to the relay must not exceed 2/3 of the maximum load
current indicated in its specification.
The voltage relay is designed for operation indoor only. The device operation is
inadmissible in places with high humidity and where ingress of liquid on its case
is possible. Ambient temperature during the voltage relay operation must be in
the range +10 to +35 °С.
7. PREPARATION TO OPERATION
VR-101F voltage relay has fixed settings and does not need programming or
additional settings.
8. OPERATION
The voltage relay has the following operation modes:
• normal operation;
• protection mode;
• turn-on delay mode.
The voltage relay is in normal operation, when the active voltage of the power
supply network is within 185-255 V limit and the turn-on delay time is over. In
this mode the protected equipment connected to the relay is de-energized, the
indicator lights continuously.
If the voltage exceeds the set thresholds, the relay enters the protection mode.
In this mode the equipment connected to the relay is de-energized and one of
protection indicators starts to light: when high voltage protection is actuated
or when low voltage protection is actuated. The voltage relay will be in this

mode as long as the supply voltage attains a value within 190-250 V range.
The relay enters the turn-on delay mode after its connection to the power sup-
ply network or when it leaves the protection mode. In this mode the equipment
connected to the relay remains de-energized till the end of delay time, and
indicator blinks during this time. The turn-on delay value for VR-101F voltage
relay is 180 sec.
Force transition from the turn-on delay mode to the operation mode can be
done by pressing button .
