Cautions
1. This product may cause an electric shock in handling. Please do not attempt to open it with power turned on.
2.This product should be installed in a place fixed secured by a rack or panel.
3.This product can be used under the following environmental conditions:
● Indoor
4. Power input must be within the designated ranges.
5. To turn on or turn off power supply for this product, please use the circuit breaker or switch of a standard product of
IEC 60947-1 or IEC 60947-3 product and install it within a close distance allowing convenient operation by user provided.
6. An output wire to be used for this product should be inflammable grade FV1(v-1 grade or above). The thickness of
the wire should 0.08mm²~1.3 mm²
7. In order to prevent it from an inductive noise, please maintain the high-voltage wire and power wire separated.
8. Please avoid installing the product in a place where a strong magnetism, noise, severe vibration and impact exist.
9. When extending the sensor wire, use a shield wire and do not extend it unnecessary long.
10. The sensor wire and signal wire should be away from the power and load wires using conduits separately installed.
11. Please avoid using the product near a device generating strong high frequency noise (high frequency welding machine,

If you want modify parameters table 3, please change DIP SW first. (See page5) 2) Because the controller screen display maximum value is 999,so 40043EEV total stepspulse50 means 500 steps.
