Installing the A77
1.1
Mounting the A77
When mounting the A77 in ANY configuration, consider the size and weight of the charger. The wall, rack,
and/or floor must be able to support the weight of the charger as well as an additional safety factor. Verify the
weight of the A77 charger using Appendix A or Appendix B, and the method of mounting using Table 1 below.
The location chosen for the charger should be within an ambient temperature range of 32 to 122
˚
F (0 to 50
˚
C)
with a non-condensing relative humidity no higher than 95%. The A77 should be mounted in an area free of
explosive materials and away from drips and splatter. The A77 utilizes convection cooling so a clearance of at
least 6in (152mm) of free air must be maintained on the top, bottom and both sides for cooling air. Maintain
36in (914mm) or more of clearance at the front of the charger in order to allow for operation and maintenance.
