                                 Avoid using the product in a place where the main unit or controller may come in contact with water or  oil droplets.   Never cut and/or reconnect the cables supplied with the product for the purpose of extending or  shortening the cable length. Doing so may result in fire.    [Operation]   Do not enter the machine’s range of operation while the product is operating or standing by. The  actuator may move suddenly, causing injury.   Do not pour water onto the product.

                              Prohibited Handling of Cables    When designing an application system using IAI’s actuators and controllers, incorrect wiring or connection  of each cable may cause unexpected problems such as a disconnected cable or poor contact, or even a  runaway system. This section explains prohibited handling of cables. Read the information carefully to  connect the cables properly.        1. Do not let the cable flex at a single point.  Steel band    (piano wire)                Bundle loosely.

                                7. Notes on using cable bearers       The supplied cables are not robot cables. Accordingly,   never store the cables in a cable bearer.                       Always use a robot cable   for each relay cable.  Bending radius (r)           Use a cable bearer with a bending    radius (r) of 50 mm or greater.       Do not let the cable get tangled or kinked in a cable bearer or flexible tube. When bundling the cable,  keep a certain degree of flexibility (so that the cable will not become to
