7.18 HMXPS9 SYSTEM POWER SUPPLY
7.18.1
Output Protection For HMXPS9
The HMXPS9 power supply is fitted with 5 Amp self-resetting switches (fuses) to all
outputs. Therefore, apart from the mains input fuses, there are no parts/devices in the
HMXPS9 that require replacement by on-site personnel. Care should be taken to ensure
individual outputs are not overloaded, or bordering on overload, as this may result in the
self-resetting switches activating periodically.
The HMXPS9 unit is manufactured for standard 19-inch rack mounting. Each HMXPS9
rack mount chassis requires 3.5" of rack space. The mounting holes are in accordance
with EIA RS-310 standard. The mounting holes are for #10 mounting screws.
7.18.2
Interconnecting HMXPS9 to Canon Style Sockets
Where a subrack, RD-18, RD-9016 or similar is to be connected to a HMXPS9 and is
fitted with a CANON style connector, it will be necessary to remove this connector and fit
a MATE-N-LOK style. The following illustration (MG10043) details the corresponding pin
connections to assist in changing the connector.

WARNING: Please ensure 1RU of rack space is left
above each HMXPS9 when installed into system racks to
allow for ventilation.

WARNING: Please ensure that the correct fuses are
installed prior to installation.
WARNING: Whilst the HMXPS9 has four output sockets,
care must be taken to avoid overloading the power
supply due to multiple heavy loads. No more than two
fully populated 6RU video subracks, including text
outputs, (e.g. HMX32128 or similar) should be connected
to a single HMXPS9.
