3.01 Environment SECTION 3: INSTALLATION RECOMMENDATIONS The ARC MASTER 400 MST is designed for use in hazardous environments. Examples of environments with increased hazardous environments are:a. In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts. b. In locations which are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or accidental contact by the operator. c. In wet or damp hot locations where humidity or perspiration considerably reduces the skin resistance of the human body and the insulation properties of accessories. Environments with hazardous environments do not include places where electrically conductive parts in the near vicinity of the operator, which can cause increased hazard, have been insulated. 3.02 Location Be sure to locate the welder according to the following guidelines: • In areas, free from moisture and dust. • Ambient temperature between 0 degrees C to 40 degrees C. • In areas, free from oil, steam and • In areas, not subjected to abnormal corrosive gases. • In areas, not exposed to direct sunlight or rain. 15 vibration or shock. • Place at a distance of 12” (304.79mm) or more from walls or similar that could restrict natural airflow for cooling. WARNING 3 Thermal Arc advises that this equipment be electrically connected by a qualified electrician. 3.03 Electrical Input Connections WARNING 4 ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is present after removal of input power. DO NOT TOUCH live electrical parts. SHUT DOWN welding power source, disconnect input power employing lockout/tagging procedures. Lockout/tagging procedures consist of padlocking line disconnect switch in open position, removing fuses from fuse box, or shutting off and red-tagging circuit breaker or other disconnecting device.
