Section 2 — Installation
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.
WARNING
The switcher frame weighs approximately 175lbs. (67 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 Switcher 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.
CAUTION
To avoid static damage to sensitive electronic devices, protect the Model 2200
Digital Switcher from static discharge. Avoid handling switcher modules in a high
static environment. Touch the switcher 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.
