For more details, refer to Safety recautions for Floatless Level Controllers. 4. It is recommended that the cable length be kept as short as possible since the Electrode current is at DC micro-current level. Moreover, the Electrodes will corrode rapidly if the current is allowed to constantly flow between the Electrodes. Be careful with the electrode polarity and grounding when wiring.

If long leads are used, the floating capacity of the leads, and abnormal surges or noise in the Electrode can cause malfunctions. The thicker the cables, the shorter the permitted wiring length. The length of the cable connecting the Controller and Electrode is specified in the Controller datasheet as a guideline assuming that a 00-V VCT 0.-mm, -core cabtire cable is used. Test results indicate that the actual wiring length using VCT.-mm, -core cable laid over the ground is 0% of the specified length for general-purpose applications and 80% of the specified length for long-distance applications. When selecting cable specifications, remember that the wiring length is further decreased for underground cables and larger diameter cables because of the increased floating capacity with the ground.
