Page 10: Operating Environment
Document No.ZL-OM01001 Operating Environment - Do not use in an environment where corrosive gases, chemicals, sea water, water or steam are present. These can cause failure or malfunction. - Do not use the product in a place where the product could be splashed by oil or chemicals. If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires). -
Page 11: Mounting And Installation
Document No.ZL-OM01001 Mounting and Installation 1. Tighten the body to the recommended tightening torque (For top and side mounting: 1.2 to 1.5N･m, for bottom mounting: 0.60 to 0.74 Nm ). If the recommended tightening torque is exceeded, the body, mounting screws and brackets may be damaged. Insufficient torque can cause displacement of the body from its proper position and the looseness of the mounting screws. -

Page 15: Electrical Wiring
Document No.ZL-OM01001 Electrical wiring 1. Use the specified voltage. Otherwise failure or malfunction can occur. 2. Do not exceed the specified maximum allowable load. Otherwise it can cause damage or shorten the life of the product. 3. Design the product to prevent reverse current when the circuit is opened or the product is forced to operate for operational check. -
Page 16: Solenoid Valve
Document No.ZL-OM01001 Solenoid Valve 1. Avoid energizing the solenoid valve for long periods of time. If a solenoid valve is continuously energized for an extended period of time, the heat generated by the coil assembly may reduce performance and life of the valve or have adverse effects on peripheral equipment. Therefore, when it is continuously energized for an extended period of time or when the energized period per day is longer than the de-energized period, use N.O. -
