Cradle Installation 8 - 7
System Cabling
There are some general limitations that must be taken into account when designing a dispenser and ordering
hardware elements of a system:
No more than six cradles can be powered off of one power supply and power cable 25-66420-01R.
No more than 12 cradles can be powered off of one power supply and “Y” power cable 25-67592-01R.
No more than six cradles can be powered off each leg of the “Y” power cable.
A power supply cable runs from the power supply to one or two cradles.
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 enclosure.
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 furniture, cable routing should be as direct as possible. Routing should follow vertical
and horizontal runs through the modules. As part of each power supply that is shipped is a set of labels
numbered 1 through 12. These labels are to be used to track the number of loads on a particular supply.
Each label is affixed 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 8-10 shows how the maximum number of cradles can be cabled to a power supply using power cable
25-66420-01R.
Figure 8-11 shows how the maximum number of cradles can be cabled to a power supply using the “Y” power
cable 25-67592-01R. Note that there are only six cradles per leg of the power supply cable, and only 12
cradles in total.
