21. Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is
not caused by uneven mechanical loading.
22. Circuit Overloading
Consideration should be given to connection of the equipment to supply circuit and
the effect that overloading of circuits might have on over-current protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
23. Reliable Earthing (Grounding)
Reliable grounding of rack mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the
branch circuit (for example, use of power strips).
Lithium Battery
The unit contains a single 3 VDC lithium battery. This battery is used to maintain the
real-time clock of the unit. When power is not applied to the unit, the battery is used to
maintain the clock and retain the correct clock setting specified by the installer. After
several years of operation, it may become necessary to replace this battery. If the
battery fails, the unit clock will reset to 2001-01, 01 00:00:00. Contact Honeywell
Technical Support for assistance with this. The old battery should be discarded at an
appropriate waste site for lithium batteries as per local guidelines in your area.
