1. Important Notes

Solid state equipment has operational characteristics differing from those of electromechanical equipment. 
Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls describes some important  differences between solid state equipment and hard-wired electromechanical devices. 
Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons  responsible for applying this equipment must satisfy themselves that each intended application of this equipment is  acceptable. 
In no event will CREVIS be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment. 
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables  and requirements associated with any particular installation, CREVIS cannot assume responsibility or liability for actual  use based on the examples and diagrams.

Warning! 
 If you don’t follow the directions, it could cause a personal injury, damage to the equipment or explosion          
 Do not assemble the products and wire with power applied to the system. Else it may cause an electric arc, which  can result into unexpected and potentially dangerous action by field devices. Arching is explosion risk in hazardous  locations. Be sure that the area is non-hazardous or remove system power appropriately before assembling or  wiring the modules. 
 Do not touch any terminal blocks or IO modules when system is running. Else it may cause the unit to an electric  shock or malfunction. 
 Keep away from the strange metallic materials not related to the unit and wiring works should be controlled by the  electric expert engineer. Else it may cause the unit to a fire, electric shock or malfunction. 

Caution! 
 If you disobey the instructions, there may be possibility of personal injury, damage to equipment or  explosion. Please follow below Instructions. 
• Check the rated voltage and terminal array before wiring. Avoid the circumstances over 55℃ of temperature.  Avoid placing it directly in the sunlight.  
• Avoid the place under circumstances over 85% of humidity.  
• Do not place Modules near by the inflammable material. Else it may cause a fire. 
• Do not permit any vibration approaching it directly.  
• Go through module specification carefully, ensure inputs, output connections are made with the specifications. Use  standard cables for wiring.  
• Use Product under pollution degree 2 environment..
