3. INTENDED USE

3.1. Preparation for operation

3.1.1. Preparation for connection:

 Unpack the product (we recommend to keep the original packing for the entire warranty period of the

product operation);

 Check the product for damage after transportation; in case of such damages detection, contact the

supplier or manufacturer;

 Carefully study the Operation Manual (pay special attention to the connection diagram to power

the product);

 If you have any questions regarding the installation of the product, please contact the manufacturer by

telephone number indicated at the end of this Operating Manual.

3.1.2. General

If the temperature of the product after transportation or storage differs from the temperature of the
environment at which it is supposed to be operated, then before connecting to the mains hold the product
under operating conditions within two hours (because there is possible moisture condensation on the
elements of the product).

ATTENTION!

THE PRODUCT IS NOT DESIGNED FOR LOAD COMMUTATION IN CASE OF SHORT CIRCUITS.
THEREFORE, THE LOAD POWER SUPPLY CIRCUIT SHOULD BE EQUIPPED WITH THE CIRCUIT
BREAKER FOR CURRENT OF 6 A MAXIMUM.

ATTENTION! ALL CONNECTIONS MUST BE PERFORMED WHEN THE PRODUCT IS DE­ENERGIZED.

Error when performing the installation works may damage the product and connected devices.

To ensure the reliability of electrical connections you should use flexible (stranded) wires with insulation for
voltage of no less than 450 V, the ends of which it is necessary to be striped of insulation for 5±0.5 mm and
tightened with bootlaces. The cable cross section to connect the load depends on current (power) of the load.
For example for the current of 6 A it is no less than 1.5 mm2. Wires fastening should exclude mechanical
damage, twisting and abrasion of the wire insulation.

IT IS NOT ALLOWED TO LEAVE EXPOSED PORTIONS OF WIRE PROTRUDING BEYOND THE
TERMINAL BLOCK.

For reliable contact it is necessary to perform tightening of screws of the terminal block with the force
specified in Table 1.

When reducing the tightening torque, the junction point is heated, the terminal block may be melted and
wire can burn. If you increase the tightening torque, it is possible to have thread failure of the terminal block
screws or the compression of the connected wire.

To improve operational properties of the product it is recommended to install the fuse or its
analogue for 1 A current in power supply circuit for REV-120.

3.2. Product connection

3.2.1. Adjustment of the product

Before connecting the device, you should configure it. Its setting is performed in the following order:

• The operation mode adjustment;

• The time interval adjustment;

• The time delay adjustment.

For precise positioning the regulators ∆T and W it is recommended to rotate them to the extreme left and
then turning right to count the desired number of positions (fixation of position).

Note – when changing the operation mode or time intervals of the product under the power supply, it is
necessary to consider that the changes will take effect only after de-energizing (for at least 1 s) and re­energizing of the product.

ATTENTION! Not to break or rotate the regulators to excessive extent, please do not use excessive
force when performing installation operations.

3.2.1.1. The product operation mode adjustment

List of the REV-120 operation modes is given in table 3.

Find the desired mode of the product operation according to Table 3 and set the regulator for the operation
mode setting W to the required position (Fig.1 it.5).
