Alert Indication The safety precautions are divided into “Danger”, “Warning”, “Caution” and “Notice” according to the warning level, as follows, and described in the instruction manual for each model. Level Degree of Danger and Damage Symbol This indicates an imminently hazardous situation which, if the product Danger Danger is not handled correctly, will result in death or serious injury.
Caution in Handling 1. Make sure to follow the usage condition, environment and specification range of the product. In case it is not secured, it may cause a drop in performance or malfunction of the product. 2. Do not attempt to have any handling or operation that is not stated in this Instruction manual.
10. For PCON-CB and MCON Controllers (with option: T), it is available to switch over the setting between effective and ineffective of the high-output setting in the parameter setting. (In the setting at delivery, the high output setting is set to effective.) For MSEL Controller, the high output setting is effective and cannot switch it over to ineffective.

2. Installation 2.1 Transportation [1] Handling of Robot (1) Handling the Packed Unit Unless otherwise specified, the actuator is shipped with each axis packaged separately. • Do not damage or drop. No special treatment is conducted on this package to endure a drop or impact on it.
Page 72
Handling in the Assembled Condition This is the case when the product is delivered from our factory under a condition that it is assembled with other actuators. The combined axes are delivered in a package that the frame is nailed on the lumber base. Fix the rod so that would not accidentally move during transportation. The actuators are also fixed so the tip of it would not shake due to the external vibration.
2.2 Installation and Storage • Preservation Environment Installation Environment The actuator should be installed in a location other than those specified below. In general, the installation environment should be one in which an operator can work without protective gear. Also provide sufficient work space required for maintenance inspection. •...
