OVP-11f

6. CONNECTION

OVP-11F voltage relay is connected to a standard socket of 220 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 OVP-11F. 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

OVP-11F 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 a 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: b when high voltage protection is

actuated or c 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.
