Installation Overview
Both distribution amplifiers can be mounted on tabletops, under
furniture, and in racks by following these steps:
1
. Turn off all electrical equipment. Make sure that the input
sources, the DA and the output display(s) are all turned off
and all power sources and signal cables are disconnected.
2 . Mount the unit as described in "Mounting the Distribution
Amplifier", below.
3 . Connect the Cables (see "Cable Connections" on page 2-8).
4 . Plug in the power supply, then turn on the display devices
and input devices (see "Operation" on page 2-11).
Mounting the Distribution Amplifier
The 1 U, half rack size of the distribution amplifiers allow them
to be mounted in racks, under furniture or on tabletops.
Tabletop placement
Attach the four provided rubber feet to the bottom of the unit
and place it in any convenient location.
Rack mounting
UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines are
relevant to the safe installation of these products in a rack:
1
. Elevated operating ambient temperature — If the unit
is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore,
install the equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2 . Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
3 . Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
4 . Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings when addressing this
concern.
