Section 2 — Installation
WARNING
The Model 4000 Digital Signal Processor Frame weighs approximately 300
lbs (136 Kg) when fully configured. Provide appropriate equipment to
support the Frame during installation.
Do not lift the Control Panel, by the lid. The lid could open causing the unit to
fall creating a hazard to personnel and/or damage to the equipment.
WARNING
The Signal Processing Frame power supply assembly exhibits high leakage
(fault) currents due to the EMI suppression filter system. This power supply
chassis must be connected to earth ground via the ground wire provided in
the AC input cord. An additional ground lug is provided on the rear of the
power supply chassis for supplementary grounding purposes.
WARNING
Electrical potential is still applied to some internal components even when
the power switch/breaker is in the off position. To prevent electrical shock
when working on this equipment, disconnect the AC line cord from the AC
source before working on any internal components. A residual voltage may
be present immediately after unplugging the system due to large power
supply capacitors discharging. Wait thirty seconds to allow capacitors to
discharge before working on the system.
CAUTION
To avoid static damage to sensitive electronic devices, protect the Model 4000
Digital Switcher from static discharge. Avoid handling switcher modules in a high
static environment. Touch the Signal Processor Frame before you remove any
modules. This helps ensure that any potential difference between your body and
the frame is dissipated. If you handle the modules or make any repairs to them use
a grounding strap and grounded equipment.
