Precautions for Safe Use 1. Precautions for the environment  Use and preserve within the proper temperature and humidity described in the specifications.  Temperature of surroundings for preservation (including during transportation) and use: −10 to 55°C, humidity: 45 to 85%.  Do not install, among others, near heat devices such as coils or other devices having coils, etc.  Avoid preserving (including during transportation) and using in a humid place, in a corrosive gas environment, outdoors and in a place which receives direct sunlight.  Preserve and use without exposing to danger of explosion, flamma- ble dust, gas and vapor, excessive dust, and saline spray or drop- lets.  Avoid preserving (including during transportation) and using in a place which is vulnerable to flooding or oil spillage.  Avoid preserving (including during transportation) and using in a place where vibrations and impacts are strong. Similarly, avoid using next to a high-capacity contactor which may impacts at oper- ation. Doing so causes malfunctions such as chattering, etc.  Do not install the product near devices generating strong high-fre- quency waves or surges. When using a noise filter, check the volt- age and current and install it as close to the product as possible. 2. Cautions for Use  Read the instruction manual and catalog before operating and maintaining the product.  Fit socket(s) and DIN rail(s) so that the screws are tight. If the screws are not tight, DIN rail(s), socket(s), the product and cable(s) may lead to come off.  Be sure to fit socket(s) to DIN rail(s) without fail.  Use metal strengthener(s) to maintain a firm connection between the product and socket(s).  Read the instructions manual and catalog before the operation and maintenance of the product.  When fitting crimping terminal(s) to terminal screw(s), use a tight- ening torque of between 0.45 and 0.6 N·m  Use power supply of appropriate specifications to provide control source(s), inputs, etc., and to wire cables. [Recommended cable to wire between the model 61F and elec- trode(s) when using three-core cabtire cable(s) of completely insu- lated 600 V 0.75 mm VCT: 50 m max.]  Do not put power line(s), high-voltage cable(s) and wire(s) of elec- trode circuit(s) in the same duct nor wire closely. Doing so causes malfunctions by getting vulnerable to induction noise.  Shorten the distance for wiring between the model 61F and elec- trode holders as much as possible. Long distance for wiring may causes malfunctions because stray capacitance may influence operation, or abnormal surges or noise may run through electrode circuit(s).  Be sure to ground common electrode terminal(s). Doing so can reduce some effects of noise.  Use the product within the noted supply voltage and rated load.  Before using, recheck the application, wiring, power supply, etc. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
