Cradle Installation
140
• Cradle interconnection cables run between each successive cradle in the chain.
• The power supply is air cooled, and as such expects some circulation of fresh air around it. Do not enclose
it in a small airtight location.
• Power supplies must be mounted in their natural, landscape orientation. They contain fans and their vents
must allow for the free flow of air.
• Power supplies should be mounted either above or below dispensers and entrance heads. Mounting of
power supplies to the right or left is not preferred.
• When laying out your furniture and cabling plan, routing should be as direct as possible. Routing should
follow vertical and horizontal runs through the modules. A set of labels, numbered 1 to 12, is part of each
power supply unit. These labels are to be used to track the number of loads on a particular supply. Each
label is designed to be attached to the cradle interconnection cable when a cradle is added to the daisy
chain. When all labels are used, the supply is fully loaded.
Figure 101 on page 140 shows how the maximum number of cradles can be cabled to a power supply using
power cable CBL-DC-394A1-01.
Figure 102 on page 141 shows how the maximum number of cradles can be cabled to a power supply using
the “Y” power cable CBL-DC-392A1-02. Note that there are only six cradles per leg of the power supply cable,
and only 12 cradles in total.
