7. Each crimp terminal or conductor pole should be connected in parallel as shown in
the Fig. 1. When mounting more than one breaker side by side, fit insulation barriers between
breakers. If the breaker has no interphase barrier, insulate the exposed part of the crimp
terminals or conductors with insulation sleeves or tape, or attach terminal covers.(sold
separately)
8. Be sure to ground the ground terminals of electrical devices
9. Be sure to install the interphase barriers between the power supply terminal phases
as shown in the Fig.2.
10. When the circuit breaker trips of itself, remove the cause and
turn the handle on. Or else, it may lead to the fire accident.
11. Do not modify the device unless it is permitted. 12. When the device become
useless, it should be dispose of them as an industrial waste.
OTHER CAUTIONS
1. Perform an operation check at least once in a month by pushing the test button of
ELCB.
2. Measuring insulation resistance between phases or dielectric strength test between
phases are not available for ELCB. To do them, remove the breaker from the circuit in
advance.
3. Do not send by portable transceiver (ex, 5W,27,140,430,900 MHz) whthin 1m of this
container, or the ELCB may malfunction.
4. Be careful not to be damaged by accidents during tranportation or installation.
5. Refer to the catalogue for further details.
