Warnings and Cautions
Warning SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the Microwave Switch modules. Before you remove
any installed module, disconnect AC power from the mainframe
and from other modules that may be connected to the
Microwave Switch.
Caution MAXIMUM POWER. The maximum power that may be applied
to any SMA input connector is 1 W (CW). The maximum voltage
that may be applied to the EXTERNAL B+ terminal is 42Vpk.
CONNECTING +5V/+12V. For the Microwave Switch, the
mainframe backplane +5V is fused at 4A, and the +12V line at
4A. The total current drawn by all coaxial switches connected
to the Microwave Switch module must not exceed the fuse
rating of the supplies (mainframe and/or external) used.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the Microwave Switch modules, observe
anti-static techniques whenever removing a module from the
mainframe or whenever working on a module.
