16 | section 2 2.9 Power Input and Grounding Safety 2.9 Power Input and Grounding Safety. The AC input connects mains power to the unit with a standard IEC power cord. The power supply has a universal AC input, accepting a range from 100 to 240 VAC, 50-60 Hz, at 0.15 - 0. 075 Amps. IMPORTANT SAFETY INFORMATION Surge Protection Precautions should be taken to prevent damage caused by power surges. WARNING The <strong>Hx1</strong> and <strong>Hx2</strong> use a universal-input power supply, which has an internal fuse. Hazardous voltages may still be present on some of the primary parts even when the fuse has blown. The power cord is the primary disconnect mechanism. Mains power should be near the equipment and easily accessible. The unit should not be positioned such that access to the power cord is impaired. If the unit is incorporated into a rack, an easily accessible safety disconnect device should be included in the rack design. Grounding This equipment is designed to be operated from a power source which includes a third grounding connection in addition to the power leads. Do not defeat this safety feature. In addition to creating a potentially hazardous situation, defeating this safety ground will prevent the internal line noise filter from functioning. Should you replace the power supply module in the future, be sure to re-connect the safety ground wires as shown in the illustration below. Inside the chassis near the power inlet is a ground stud. The ground wire from the power inlet is attached to the ground stud with a star washer on either side of the wire terminal. (See above figure). A nut is used to independently tighten the inlet ground wire to the chassis. Next, the ground wire from the power supply is fastened to the ground stud with a star washer on either side of the wire terminal. An additional nut is fastened to the top of the ground stud.
