3.7 Low Voltage Directive

When using in the application confirming to EN61010-1/IEC61010-1, make sure to satisfy the following
conditions.
(1) Pulse output part secure only basic insulation. In order to secure reinforced (double) insulation
demanded by EN 61010-1/ IEC61010-1, secure basic insulation or more with load side and
reinforced (double) insulation with communication system side.
(2) Provide the voltage input part with an EN60947-1 or EN60947-3 compliant circuit breaker.
The breaker that connects to the voltage input part must arrange at the position easily reached,
and display shows it is the breaker of the equipment.
(3) Use a wire with basic insulation or more for a wire cramped (or connected) CT.
