2 | Transportation | - When carrying a heavy object, do the work with two or more persons or utilize equipment such as crane.
- When the work is carried out with 2 or more persons, make it clear who is to be the “leader” and who to be the “follower(s)” and communicate well with each other to ensure the safety of the workers.
- When in transportation, consider well about the positions to hold, weight and weight balance and pay special attention to the carried object so it would not get hit or dropped.
- Transport it using an appropriate transportation measure.
The actuators available for transportation with a crane have eyebolts attached or there are tapped holes to attach bolts. Follow the instructions in the instruction manual for each model. - Do not step or sit on the package.
- Do not put any heavy thing that can deform the package, on it.
- When using a crane capable of 1t or more of weight, have an operator who has qualifications for crane operation and sling work.
- When using a crane or equivalent equipments, make sure not to hang a load that weighs more than the equipment’s capability limit.
- Use a hook that is suitable for the load. Consider the safety factor of the hook in such factors as shear strength.
- Do not get on the load that is hung on a crane.
- Do not leave a load hung up with a crane.
- Do not stand under the load that is hung up with a crane.

4 | Installation and Start | (3) Grounding - The grounding operation should be performed to prevent an electric shock or electrostatic charge, enhance the noise-resistance ability and control the unnecessary electromagnetic radiation.
- For the ground terminal (PE) on the AC power cable of the controller and the grounding plate in the control panel, make sure for grounding work. For security grounding, it is necessary to select an appropriate wire thickness suitable for the load. Perform wiring that satisfies the specifications (electrical equipment standards and criteria).
For detail, follow the description in an instruction manual of each controller or controller built-in actuator. - Conduct functional grounding on the FG terminal for a controller supplying 24V DC or a controller built-in type actuator. In order to minimize influence to mechanical operation given by electromagnetic interference (noise) to an electrical device or insulation failure, conduct grounding on a terminal or a conductor that is electrically stable. The reference impedance should be Type D (Former Class 3, ground resistance 100Ω or less).
