APPEARANCE The device is designed for three-phase instal- lation and must be in- stalled in accordance with standards valid in CAUTION a particular country. The device should be connected according to the details included in this operating manual. Installation, connection and control should be carried out by a qu- alified electrician staff, who act in ac - cordance with the service manual and the device functions. Before installation make sure the connection cables are RELAY not under voltage. The cruciform head CABLES Power supply cable / screwdriver 3,5 mm should be used to measure (L1) instal the device. Improper transport, Measure cable (L2) storage, and use of the device influence its wrong functioning. It is not advisable Measure cable (L3) to instal the device in the following ca- Power supply cable (N) ses: if any device part is missing or the device is damaged or deformed. In case of improper functioning of the device contact the producer.

Disconnect the power supply from the mains by the phase fuse, the circuit- breaker or the switch-disconnector that are joined to the proper circuit/ 2. Check if there is no voltage on con- nection cables by means of a spe- cial measure equipment. 3. Fasten the CAH-01 to the base with the screw. NOTICE It is forbidden to bore fitting holes in the cover It may result in the loss of containment of the cover and by this the loss of guarantee PROTECTED 4. Connect the cables CAH-01 with the CIRCUIT hermetic installation junction box ac- cording to installing diagram. 5. Switch on power supply from the ma- ins. After the power supply has been applied (supply from the phase L1) the sensor controls voltage value of particu- lar phases. In case it is correct on every phase the sensors relay switches on, and the load (motor) operates. In case there is a lack of any of the phases or there is a voltage drop below the adju- sted asymmetry threshold (185 V) the re- lay is switched off (load switch off).There is a short time delay in switching off the relay (t from 1 to 5 sec). The device is 2 resistant to momentary voltage drops. Another device switch on follows when the voltage on a particular phase is abo- ve 195 V and exceeds t time (from 5 sec 1 to 10 sec). Voltage hysteresis (about 10 EXAMPLE OF INSTALLATION V) switch off delay make the system resi- stant to momentary voltage drops. PRODUCT FAMILY The CAH-01 is a member of the CAx phase sequence sensor family.
