Based on IEC60529 Note) Impact resistance: No malfunction occurred when it is tested in the axial direction and at the right angles to the main valve and armature in both energized and de-energized states every once for each condition. (Values at the initial period) Vibration resistance: No malfunction occurred in a one-sweep test between 45 and 2000 Hz. Test was performed at both energized and de-energized states in the axial direction and at the right angles to the main valve and armature. (Values at the initial period) Note) Based on dynamic performance test, JIS B 8375-1981.

Can not be used in a class-0 environment. Use in a class-2 or class-1 environment. Note 1) Warning The valve and barrier have polarity. If voltage is supplied with wrong polarity, the barrier can not be used. Note 2) Caution Note 3) Caution Voltage to the valve should be 10.8 VDC (minimum value). IIBT4 A
