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.
