CAUTIONS FOR USE
1. Installation 1) Perform mounting hole cutout according to the panel cutout drawings. 2) When installing the unit on a DIN rail, use the DIN rail locking lever on the side of the unit. Installation is accomplished by simply fitting the unit onto the rail and pressing gently. 2. Removal of cover 1) Insertions and withdraws of connector can be done by lifting the cover like 1. 2) Wiring to the terminal can be done by lifting the cover like 2. 3) Removal of the cover can be done by lifting it like 3. 4) In case of resetting the cover, please push the cover like 4. 1 2 3) In order to improve noise resistance, class 3 grounding of the control panel is recommended. 4) Turn off the power before connecting/ disconnecting connector cables. 4. Operating environment 1) Use the product at ambient operating temperature between 0C and 55C 32F and 131F. 2) The main unit is made of resin; therefore, do not use it in areas where it may come in contact with (or be exposed to) organic solvents such as benzine, thinner, and alcohol or strong alkaline substances such as ammonia and caustic soda. 3) Do not use the product in areas where it may be exposed to flammable gases, corrosive gases, excessive dust, or moisture, or areas where it may be subjected to strong vibration or shock. 5. Transporting and storage 1) If the product is subjected to extreme vibration while being transported, the relays may become detached, the lead may become bent, and the unit may become damaged. Handle the inner and outer boxes with care. 2) If the product is stored in an extremely adverse environment, visible defects and deterioration of performance characteristics may result. We recommend the following storage conditions. * Temperature: 5 to 30C 41 to 86 F * Humidity: Max. 60% R.H. * Environment: No hazardous substances such as sulfurous acid gases and little dust.
1 First push in the DIN rail locking lever. DIN rail locking lever DIN rail 3 Press the unit onto the DIN rail.
2 Hook the holders on the unit over the DIN rail.
3) To remove the unit from the DIN rail, use a flat head screwdriver to pull out the DIN rail locking lever.
3 Remove the unit from the DIN rail.

2 Move the screwdriver in the direction of the arrows, and pull out the lever.
1 Insert the tip of the flat head screwdriver into the slot in the DIN rail locking lever.
4) Be careful not to drop or shock the unit. Excessive shock such as dropping may cause damage or malfunction.
3. Wiring and circuit configuration 1) Make all connections according to the schematic. 2) When wiring power lines or power cables, twisted pair treatment (standed wire treatment) should be done in order to improve noise resistance.
