Purpose

Before the installation and operation of the device, please read by the end of this document. This will help to avoid possible danger, mistakes and misunderstandings.
The quality of circuit voltage must meet the state standards and equal to 230 V with minor deviations. At this voltage oriented manufacturers of home appliances during designing and manufacturing. But real supply voltage does not always correspond to this standards. May occur surges from 160 to 380 V, caused by a number of factors including the following:
— break and getting zero wire on one of the phases of overhead power lines (most common in the private sector, where dominated overhead power lines);
— a skew phases, caused by overload of one of the phases of some powerful customer;
— outdated equipment substations that doesn’t meet the consumers power that increased.
The list of protected electrical and electronic equipment, is next: Current domestic consumers such as refrigerators, televisions, video and  audio, computers and other electrical equipment that could be sensitive to deviations of supply voltage.

Warning! It is forbidden to use voltage relay to protect equipment, which runs from the sources of modified sine, uninterruptible power supply output voltage sinusoid are not Long operation (more than 5 minutes) from the following sources voltage may damage ZUBR and lead to not warranty repair.

Supply package

Connection scheme

Supply voltage (100 – 420 V, 50 Hz) served on termi- nals 1 and 2, while phase (L) is determined by the indicator and activated on terminal 2 and neutral (N) — terminal 1.
The connecting voltage wires connected to terminal 3 and neutral terminal block (not included).
DO NOT connect the voltage with surge zero in terminal 1!

Installation

The appliance is intended for installation inside residences. The risk of moisture or humidity in the installation site should be minimal. When installing in the bathroom, toilet, kitchen, pool appliance must be located in a shell with protection degree not below IP55 per GOST 14254 (partial protection from dust and waterproof in any direction). The ambient temperature during installation should be within –5…+45 °С.The appliance is installed in a special box, which allows to conduct the easy installation and operation. Cabinet should be equipped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of three standard module on 18 mm. The height of the appliance should be in the range 0,5…1,7 m from the floor. The appliance is installed and activated after installation and inspection of the voltage.For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit- breaker (CB). The automatic switch off is established in the open-phase fault wire, as shown at the scheme 2. It shall be calculated upon the rated load current.
To protect person from electric shock leak is set SSD (safety shutdown device).
To connect your device:
— fix the appliance on the mounting rail (DIN);
— take a wire;
— make the connection according to the passport.
Terminals of the device designed for wire cross section 2 up to 16 mm . To reduce mechanical load on the terminals it is desirable to use soft wire. Clean the end wires of
10 ±0,5 mm. If end is longer, it can cause a short circuit, and if short — cause unreliable connection. Use the cable lugs. Undo the screws of the terminals and insert tipped
end of the wire in terminal. Tighten terminal with derived average 2,4 Н·m. Low tight may lead to low contact and overheating terminals and wires and over tight — damage
terminals and wires. Wires protracted in terminals with a screwdriver with a shank width not more than 6 mm.
Scheme 2. Connection of the circuit breaker and SSD (safety shutdown device)
Screw with shank width more than 6 mm may apply mechanical damage to terminals. This could result in loss of warranty.
Cutting wires of wiring to which connects voltage relay should meet the value of electric current, which consumes voltage.
It is also necessary to take into account that the load power of 3 000 VA at 220 V will be 4 400 VA at 270 V. Therefore, please, do not allow the relay power handling to
exceed its certified value at the maximum voltage deviation to the upper limit. If the relay power handling exceeds its certified value use the electric contactor (magnetic starter, power relay) which is designed for this power capacity.

Exploitation

Enabling
When you turn on the appliance, it immediately begins to indicate the main voltage. If the voltage is within acceptable limits, turns on loading and green indicator.
The value of voltage that has exceeded the limit will flash alternating with «U », if the lower limit is exceeded, and with «U », if the upper limit is exceeded.
The upper / lower limit
(factory setting 242 V / 198 V)
To view the upper limit, press the «+», button, to view the lower limit, press the «–» button. Then use the «+» and «–» buttons to change the limit as necessary. In 5 sec after the last pushing buttons relay return to indication of main voltage.
** When setting the voltage limits use the pro- tected equipment technical documentation.
Function menu (table 1)
Use the middle button to navigate through the menu.
Use the «+» and «–» buttons to change the parameters. After pressing the button for the first time the parameter will flash, after pressing it for the second time the parameter will change.
In 5 sec after the button was pressed the indicator will return to displaying the system voltage.

Delay time of load turning on
Viewing and controlling the delay are described in the function menu table.
The countdown always will be accompanied by flashing dot in the rightmost discharge indicator is set at 3 sec and more than 100 sec, and when the time remaining is less than 100 sec the display will show a countdown in seconds to the turning on of the load. If the set delay time is more than 3 seconds, in a short-term voltage jump the screen will display the maximum voltage, then the current voltage and the countdown.
For protection of refrigeration equipment, where there is a compressor, it is recommended to set a delay of turning on load 120–180 sec. It will allow to increase the service life of the compressor.
Resetting to the factory settings
To reset the factory settings, hold the three buttons at the same time for more than 12 s. until «dEF» message appears on the screen. After release, reset to factory settings and reboot will take place.
Protection from inner overheating
In case if the temperature inside the exceed 80 °C, will be emergency lockout of loading. On the screen 1 time/s (overheat) will be displayed. At this time, pressing the middle button will display the temperature of the thermal protection sensor. The device will be unlocked in case if the temperature inside will decrease to 60 °C.
If the protection trips more than 5 times within 24 hours, the voltage relay is blocked until the temperature inside the case drops to 60 °C («oht» stops blinking) and one of the buttons is pressed.
At breakout or short circuit of temperature sensor, device continues to operate normally, but every four seconds the message «Ert» , indicating the problem with sensor. In this case, control over inner overheating will not be done. Table 2 Models shutdown exit time voltage beyond.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM
At turning on neither indicator nor screen do not shine.
Possible cause: There is no power supply voltage.
It is necessary to: Ensure supply voltage presence.
After turning on the screen normal voltage level, but load is not turning on.
It is necessary to: Check the detention. In other cases, please, address to a service centre.
