Installation
7.0 Installation
The HPC is designed for use in 19 inch racks or a 19 inch bar frame, and occupies 3 or 4
rack units. The HPC is supplied with rear rack mounting support brackets, which
provide additional support for touring applications.
The mains supply power cable entry is located at the rear right side of the rack when
viewed from the front. Ensure adequate access to the power plug when mounting
HPC's in racks.
7.1
Ventilation
The HPC dimmer is fan-cooled, with the air intake at the right and air exhaust at the
left when viewed from the front. Equipment racks must have adequate ventilation for
the side-to-side airflow. Fully enclosed racks will cause overheating problems.
Racks must allow at least 100 square centimetres of air venting per HPC at each side
of the rack, level with the intake and exhaust slots. Additional venting area will serve to
further reduce internal temperatures and will enhance the HPC's operational
reliability.
HPC's may be stacked in racks without intervening rack spaces as long as the racks are
adequately vented at the sides. Racks of HPC's must be placed such that one rack does
not breathe the hot exhaust of the rack next to it. Allow at least 300mm (12") between
racks unless duty cycles are light.
The inlet air temperature must not exceed the specified maximum ambient air
temperature.
7.2
Supply Wiring
The HPC has been designed to run from commonly found star power systems, ie.
where a neutral is available. The incoming mains supply must be protected at not more
than the specified maximum.
The HPC must have its labelled terminals connected to the supply phases as indicated
in Table 3.
