*1. The circuit breaker must be installed.

Molded-case circuit breaker (MCCB) or residual current circuit breaker with overcurrent protection (RCD) can be used.

The rated interrupting capacity of the circuit breaker must be greater than the highest amount of current that could be available in the circuit.

Install MCCB (rated current 20 – 30A) that has element for each phase.

Or RCD with time-delay overcurrent protection is recommended. Recommended sensitivity current rating: 30mA

*2. Cable length between the branch point and the earthing: 0.5 meters or less recommended

*3. The protected device's metal enclosure must be cross-wired to the earth terminal of the MAT2. If the protected device has no earth terminal,

earth only the MAT2.

*4. In order to protect an electronic circuit such as measuring equipment or communication equipment, we recommend to use surge protectors

which have serial impedance incorporated such as M-System's models MAX, MMA, MAH.

■ CONNECTION EXAMPLES BY POWER SYSTEMS

Abnormal voltages appearing in case of a light load or a fault earth loop must be within the maximum continuous operational voltage when

selecting the MAT2 models.

*1. For TT system, in order to ensure safe failure mode at TOV due to earth fault on high-voltage systems, connect between terminal 2 and N of the MAT2.

*2. For TT system, in order to ensure safe failure mode at TOV due to earth fault on high-voltage systems, install a four-pole (three-pole plus neutral)

circuit breaker.

*3. For 440V AC three-phase/3-wire system, use a residual current circuit breaker with overcurrent protection.

*4. For single-phase/2-wire system, connect lines to terminal 1 and 2 of the MAT2. For single-phase/3-wire system, connect the neutral line to terminal 2

of the MAT2.

■ ALARM OUTPUT

When the alarm output is to be transmitted remotely via outdoor cables, a surge protector for the signal line is required.
