There are two manipulator cables; an encoder cable for detection (1BC) and power cable
(2BC). (Refer to "Fig. 7 Manipulator Cables (1BC and 2BC).") Connect these cables respec-
tively to the connectors at the manipulator base and the NX100. Refer to " Fig. 8 (a) Manipu-
lator Cable Connection to the Manipulator ", and " Fig. 8 (b) Manipulator Cable Connection to
the NX100 ".
• Do not use this line in common with other ground lines or grounding electrodes for other
electric power, motor power, welding devices, etc.
• Where metal ducts, metallic conduits, or distributing racks are used for cable laying,
ground in accordance with Electric Equipment Technical Standards.
