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 Operating Manual (
pay special attention to the connection diagram to power the
device
);
–
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 Device connection
ATTENTION!
OUTPUT CONTACTS OF LOAD RELAY ARE NOT DESIGNED FOR LOAD COMMUTATION IN CASE OF
SHORT CIRCUITS. THEREFORE THEY SHOULD BE PROTECTED BY AUTOMATIC CIRCUIT BREAKERS
(FUSES) WITH TRIPPING CURRENT NOT EXCEEDING 16 A OF CLASS B.
ATTENTION!
ALL CONNECTIONS MUST BE PERFORMED WHEN THE PRODUCT IS
DE-ENERGIZED.
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 cross-section of the wire for connecting the protected equipment depends on the current (power) of
the load. For example, at current 10A -
is not less 1 mm
2
.
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 removable terminal block with the force
specified in Table 1.
When reducing the tightening torque, the junction point is heated, terminal block may be melted and wire cane burn. If
you increase the tightening torque, it is possible to have thread failure of terminal block screws or the compression of the
connected wires.
To improve operational properties of the device it is recommended to install the fuse or its analogue for
1 A current in power supply circuit for REV-225.
3.1.2.1
Connect REV-225 according to the diagram indicated in Fig. 2.
ATTENTION! LOAD TERMINALS ARE DESIGNED FOR MAXIMUM VOLTAGE OF 300 V;
