Warnings and Cautions
Warning SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the multiplexer modules. Before you install any
module, disconnect AC power from the mainframe and from
user wiring.
Caution MAXIMUM VOLTAGE/CURRENT. The maximum voltage that
may be applied between High (H), Low (L), and Guard (G)
terminals is 15 V dc or 10.6 V rms (15 V peak). The maximum
current is 1 mA per channel.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the multiplexer module, observe anti-static
techniques whenever removing a module from the mainframe
or whenever working on a module.
