appropriate local or national safety procedures.
Note:
A lifting eye is provided for moving the power supply into place with a crane or hoist. It may also be moved
by forklift if the forks are long enough to extend the entire length of the base. Take care when lifting with the
forks so that the underside of the power supply is not damaged.
•
Place the power supply in an area that is free of excessive moisture, has proper ventilation, and is relatively
clean. Provide at least 3 feet (1 m) of room on all sides of the power supply to allow for easy access when
servicing, and to allow the cooling fans to function properly.
• Cooling air is drawn in through the front panel grating, and exhausted through the rear of the unit by a
cooling fan. Do not place any filter device over the air intake locations. This reduces cooling efficiency and
VOIDS THE WARRANTY.
