5.3.3 Internal Cabinet Space and Openings
The space between the rear of the Joya Cradle Dispensers and the back part of
the cabinet must be left for two reasons:
•
it must be possible to retrieve objects that accidentally fall through the
cradles from the floor behind the cabinet.
•
there must be a zone for air to freely circulate behind the Joya Cradle
Dispensers to aid their cooling during operation.
For these reasons the cabinet must not be closed at the bottom and must have
an opening at the top. To allow retrieval of objects that could accidentally fall
into the cabinet, it is necessary to leave space between the lower edge of the
lowest crosspiece and the floor. This space must be a compromise between the
necessity of allowing object retrieval and the necessity of prohibiting access
behind the cabinet.
5.3.4 Anchoring and Maintenance Issues
The cabinet must be anchored to the wall in at least two points, since the
contact surface area on the floor is small and therefore not sufficient to
guarantee full stability.
Suggestion:
It is preferable for the cabinet to have a removable back panel for easy access
inside when performing cabling.
The top of the cabinet should also be removable for access to the power
supplies during maintenance without the necessity of removing the cabinet from
the anchoring points to the wall. For this reason the power supplies should also
be able to be mounted and removed from the top of the cabinet.
5.3.5 Power Supply Positioning and Cooling
At the top of the cabinet there must be an opening not small. This opening
generates a natural convection effect allowing the flow of air to remove heat
generated by the Joya Cradle Dispensers during their operation.
The power supplies, or single power supply must be mounted on their shelf in
the upper part of the cabinet.
This position for the power supplies has been chosen to aid the flow of air inside
the cabinet taking advantage of natural convection. The hot air generated by the
power supplies, in fact, leaves through the opening at the top and takes in
cooler air from the lower part of the cabinet.
The power supplies therefore must be placed on the shelf in such a way as not
to block the flow of air coming up from the lower part of the cabinet.
