Important Safety Instructions! Review the drawings and illustrations contained in this manual before proceeding. If there are any questions regarding the safe installation or operation of the system, contact Alpha Technologies or the nearest Alpha representative. Save this document for future reference.
Alpha Technologies’ products are subject to change through continual improvement processes. Therefore, specifications and/or design layouts may vary slightly from descriptions included in this manual. Updates to the manual will be issued when changes affect form, fit or function. General Safety Precautions This enclosure and its associated hardware (power supply, batteries, cabling) may contain equipment, batteries or parts which have accessible hazardous voltage or currents.
Enclosure, equipment or parts may be damaged or cause damage if used or installed improperly. To avoid damage: • Prior to installation, verify that the AC input voltage to the enclosure and its equipment match withrespect to voltage and frequency. • Prior to installation, verify that the output voltage from the enclosure or its equipment match the voltage requirements of the connected equipment (load).
Battery Safety Notes, cont. • • • • • • • • • • If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your company’s approved chemical exposure procedures. Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with a solution of 1 lb. Bicarbonate of soda to 1 gal of water. Report chemical spill using your company’s spill reporting structure and seek medical attention if necessary.
Mechanical Safety • • • Keep hands and tools clear of fans. Fans are thermostatically controlled and will turn on automatically. Power supplies can reach extreme temperatures under load. Use caution around sheet metal components and sharp edges. Electrical Safety • • • • • • Lethal voltages are present within the power supply and electrical boxes. Never assume that an electrical connection or conductor is not energized.
