Turn off the power before checking the power and insulation resistance. Be careful not to get an electric shock while checking.

  • Page 23: Safety Instructions

    When using a manifold solenoid valve, employ a solenoid valve with an integrated "exhaust malfunction prevention valve". The 4G Series 3, 5-port pneumatic solenoid valve manufactured by CKD is recommended. Also, since a similar phenomenon occurs when the exhaust flows in from the exhaust (R) port of the SVB Series valve, do not connect the exhaust (R) port to an exhaust circuit where a back pressure may occur.
