SHOCK HAZARD. Only service-trained personnel who are aware of the
hazards involved should install, remove, or configure the RF Multiplexer.
Before you remove any installed module, disconnect AC power from the
mainframe and f other modules that may be connected to the RF
Multiplexer.
CHANNEL WIRING INSULATION. All channels that have a common
connection must be insulated so that the user is protected from electrical shock
in the event that two or more channels are connected together. This means
wiring for all channels must be insulated as though each channel carries the
voltage of the highest voltage channel.
MAXIMUM POWER. The maximum power that can be applied to any SMB
connector is 24 W (24 VA). The maximum voltage that can be applied to any SMB
connector is 42 V peak. The maximum current that can be applied to any SMB
connector is 1 A DC/AC RMS.
STATIC ELECTRICITY. Static electricity is a major cause of component failure.
To prevent damage to the electrical components in the RF Multiplexer, observe
anti-static techniques whenever removing a module from the mainframe or
whenever working on a module.
