Follow the instructions given below when designing, selecting and handling the product.
■The instructions on design and selection
described below must also be followed.
maintenance, etc.)
Product specifications
•DC power supply to be used together must be UL 1310 class 2 power supply unit or UL recognized
power supply with UL 1585 class 2 transformer.
•Use the specified voltage.
Otherwise failure or malfunction can result.
•Do not place two or more actuators close together.
When using two or more actuators closely in parallel, keep a distance of at least 40 mm between the actuator tubes
to prevent magnetic interference from affecting the product, which can cause malfunction.
(If the distance is specified for the actuator, use that value.)
•Detection by an Auto switch mounted in a mid-stroke position depends on the piston speed. Conditions
must satisfy the equation below.
Wherein;
Maximum detectable piston speed = V [mm/s]
•Design the product to prevent reverse current when the circuit is opened or the product is forced to
operate for operational check.
Reverse current can cause malfunction or damage to the product.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
■Product handling
Installation
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may be broken. If the tightening torque is
insufficient, the product can be displaced.
(Refer to "Mounting and Installation".)
•Be sure to ground terminal FG when using a commercially available switch-mode power supply.
•Never mount an actuator equipped with Auto switch in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•Do not drop, hit or apply excessive shock to the Auto switch.
Otherwise damage to the internal parts can result, causing malfunction.
