A
DANGER
Always connect the powermeter input (including current sensor) to
the secondary side of the breaker. On the secondary side of a
breaker, even if the lines are shorted the breaker can trip and
prevent an accident. On the primary side, however, the current
capacity may be large, and in the event of a short-circuit there
may be a serious accident.
Once the connections are made, do not touch the input terminals,
and the voltage and current transformers. There are exposed live
parts, and a danger of electric shock or serious accident.
Check that the terminals are tightened securely. If the connections
should become detached, there is a danger of a short-circuit or
electric shock accident. Additionally, if the connections are not
properly tightened, the contact resistance increases, which may
lead to the generation of heat, or fire.
The maximum input voltage and current for this unit depend on the
input unit being used. Do not apply an input exceeding the
maximum input voltage and current specified for the input unit.
Exceeding the maximum input voltage or current could damage the
unit or cause a serious accident.
