Degree of protection Front panel: IEC standard IP40 *3
Terminals: IEC standard IP00
Applicable Socket P2CF-08 (order separately),
P3G-08 (order separately)
Applicable Protective
Y92A-48B (order separately)

*1. At EN 61326-1 (Industrial electromagnetic environment (EN/IEC 61326-1 Table 2))
*2. No reset function is incorporated by any E5C2 model with ON/OFF control.
       The reset function is used to correct offset for proportional control. If there is an offset below the set value, turn the
       reset adjustment clockwise.
*3. A special Watertight Cover is used to achieve this degree of protection (IP66, NEMA4). Refer to Y92A-[][]N.
