TI 32P01J10-01EN
 Installation Specication
Installation Altitude
N-IO node (*1) (*2) : 3000 m or less
Other than N-IO node : 2000 m or less
Installation category based on IEC 61010-1 (*3)
Category I
• For YOKOGAWA products, category I applies to the devices that receive the electric power
not more than 33 V AC, 70 V DC.
Category II
• For YOKOGAWA products, category II applies to the devices that receive the electric power
exceeding 33 V AC or 70 V DC.
Pollution degree based on IEC 61010-1: 2 (*4)
*1: For more information about the device, refer to General Specication (GS).
*2: For S2BN4D and S2BN5D, the installation altitude is 2000 m or less.
*3: The installation category, also referred to as an overvoltage category, denes the standard for impulse voltage. The category
number from I to IV applies the devices to determine the clearance required by this standard.
Category I applies to the device intended to be connected to a power supply with impulse voltage reduced to the safe level.
Category II applies to the device intended to be supplied from the building wiring.
*4: Pollution degree indicates the adhesion level of foreign matter in a solid, liquid, or gaseous state that can reduce dielectric
strength. Degree 2 refers to a pollution level equivalent to the general indoor environment.
