Precautions
J
CONNECTING
Take the residual voltage (2 V max.) into consideration when
connecting a load or power supply.
When the internal circuit of the switch is open, there is a current
leakage of 0.15 mA max. and a residual voltage on the load.
Check the release voltage of the load before use.
J
OPERATING
Do not press the plungers located opposite each other at the
same time, or the switch could be damaged.
J
NOISE
Excessive external noise through the power line can affect the
operating accuracy of the switch (refer to the table below). If
required, use the correct noise filter to increase accuracy.
Level
1 kV p-p
1.5 kV p-p
