Preoperational Checks

After you purchase the KM50, make sure there are no dents in the KM50 or the
packaging box.
If there is internal damage, correct measurements may not be possible depending on
the location of the damage.
number Make sure that the specifications of the product you purchased match the required
specifications.
Do not block the area around the KM50 to ensure proper dissipation of heat. Do not
block the ventilation holes in the KM50.
Provide space between the KM50 Power Monitors when installing them side by side to
prevent wiring from coming into contact with adjacent Power Monitors.
When tightening terminal screws, do not subject the terminals to excessive stress.
Tighten the terminal screws to a torque of 0.69 to 0.88 N⋅m and then make sure there
are no loose screws.
Check terminal polarity and wire all terminals correctly.
Wire the power supply and voltage inputs correctly. Incorrect wiring may damage
internal circuits.
The ambient operating temperature of the KM50 is −10 to 55°C (with no condensation
or icing).
To extend the service life, install the KM50 to maintain the ambient temperature as low
as possible. If higher temperatures are unavoidable, consider using forced cooling with
a fan.
and Make sure that the vibration and shock in the installation environment do not exceed
the specified specifications.
(Install the KM50 as far away from conductors to prevent subjecting the KM50 to
vibration and shock.)
Install the KM50 so that liquids and other foreign matter will not enter it.
If sulfuric gas, chloride gas, or other corrosive gases are generated in the installation
environment, remove the source of the gas, install exhaust fans, or take other
measures to remove the gas.
