12.Precautions for cable routing and installation
12.1 Wiring methods
Various cables are used to connect the robot controller to peripheral devices. Follow the
precautions below when making cable routing and connections to avoid malfunctions due
to noise.
1) Keep the I/O cables, robot cables and power cable separate from each other. Never
bundle them together.
2) Keep the communication cable, robot cables and power cable separate from each other.
Never bundle them together.
3) Keep robot cables separate from the power cable. Never bundle them together.
4) Keep robot cables separate from other equipment power lines. Never bundle them
together.
5) The wiring of electromagnetic contactors, induction motors, solenoid valves or brake
solenoids to the I/O cable, communication cable and robot cable. Never pass them
through the same conduit or bundle them together.
6) Do not extend the ground wire longer than necessary the ground wire should be as
short as possible.
12.2 Precautions for installation
This robot controller is not designed for explosion-proof, dust-proof and drip-proof con-
struction. Do not install it in the following locations or environment:
(1) exposed to flammable gases or liquids.
(2) where conductive debris such as metal cutting chips are spread.
(3) subject to corrosive gases such as acid gases and alkaline gases.
(4) exposed to cutting oil, grinding fluids and machining mist.
(5) near a source of electrical noise, such as a large inverter, high-power high-frequency
generator, large contactor and welding machine.
12.3 Methods of preventing malfunctions
To prevent malfunctions due to noise, take into account the following points.
1) Place a noise filter and ferrite core at a point near the robot controller.
Do not bundle the primary wiring and secondary wiring of the noise filter together.
