Installation Requirements
Environmental Data
Table 3-2 lists some of the standard parts of the Scanning Platform system and the
maximum ambient temperatures in which they were designed to be used.
Table 3-2 Environmental Data for the Scanning Platform
If the temperature around the idler end column is above 50 °C, then the ASPC severe
environment option which moves the ASPC into a Remote Junction Box enclosure
is required.
Electrical Supply and Grounding Requirements
Supply
The signal-processing electronics in the Scanning Platform is chassis-grounded and
all suppression of external signal noise uses the chassis as a reference ground. If
this requirement is not satisfied, the Scanning Platform system may be sensitive to
high frequency interference from unsuppressed relays, contactors, and the discharge
of static electricity.
The main power supply to the Scanning Platform must be from the same power
supply as the host system. If there must be a deviation, then the two supplies must
be bonded to the same ground (single point earth reference).
Grounding
• The electrical connections of the reference ground are to be effective and
permanent.
• The cable shields are to be connected to the chassis with a short lead of less
than 10 cm (0.5 inch).
• The introduction of an extra grounding system such as an instrument ground is
absolutely forbidden. The system is to be grounded with a copper lead to the
distribution box (single point earth reference).
