3.0 INSTALLATION
This section describes how to install and replace the Power Supply
module and Rack.
DANGER
THE USER IS RESPONSIBLE FOR CONFORMING WITH ALL APPLICABLE
LOCAL, NATIONAL, AND INTERNATIONAL CODES. WIRING PRACTICES,
GROUNDING, DISCONNECTS, AND OVERĆCURRENT PROTECTION ARE OF
PARTICULAR IMPORTANCE. FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN SEVERE BODILYINJURYOR LOSS OF LIFE.
CAUTION: This equipment must be connected to a power source for which it was
designed. Verify that the available power is 115 volts. Failure to observe this precaution
could result in damage to equipment.
3.1 Wiring
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring between the system and the external devices. For detailed
recommendations refer to IEEE 518.
The external wiring to the modules in the Rack must be carefully
routed to minimize electrical noise and crosstalk between input and
output wiring. Group and bundle wire types by similar electrical
signals, being especially careful to separate lowĆ and highĆlevel
control signals and AC and DC wiring.
If the 115 VAC input signal is subject to severe harmonic distortion,
install a constant voltage transformer on the line.
3.2 Initial Installation
CAUTION: Thecabinetorpanelonwhichtherackismountedmustbelocatedinanarea
away from or shielded from sources of EMI, such as radar beams and transmission
towers. Failure to observe this precaution could result in damage to or destruction of the
equipment.
CAUTION: Air flow around the rack must be sufficient to dissipate the heat generated by
all of the hardware in and around the rack. Allow at least two inches of clearance on each
side of the rack. Avoid placing large, heatĆgenerating equipment underneath the rack
fans. Additional userĆsupplied fan cooling or air conditioning is required if the ambient
temperature exceeds 60_C. Failure to observe this precaution could result in damage to
or destruction of the equipment.
