（）Please connect the power supply wiring to the L and N terminals (+and – terminals for DC
specification) of the power connection terminal.
（）For the explosion-proof specification, please connect to the Type A grounding from the ground terminal.
For the non-explosion-proof specification, please connect to the Type D grounding from the ground
terminal.
CAUTION: The supply voltage shall be within the range designated on the product
nameplate which is affixed to the housing.
