Page 3 GENERAL PRECAUTIONS REGARDING THE SERVICE FOR THIS DSDF The installation and service shall be done by a qualified service technician. 1. When installing the DSDF to the Equipment, be sure to follow the instructions described in the “Unpacking/Set-Up Procedure for the DSDF” booklet which comes with each unit of the DSDF. 2.
Page 4 19.There is a risk of an electric shock or fire resulting from the damage to the harness covering or conduction blockage. To avoid this, be sure to wire the harness in the same way as that before disassembling when the equipment is assembled/disassembled. 20.After completing installation, servicing and maintenance of the DSDF, return the DSDF to its original state, and check operation.
