Warnings - HP E1563A User Manual

WARNINGS

The HP E1563A and E1564A Digitizers are capable of measuring voltages up to 256V maximum. Voltage levels above the levels
specified for accessible connectors or cable ends could cause bodily injury or death to an operator. Special precautions must be adhered
to (discussed below) when applying voltages in excess of 60 Vdc, 30 Vac rms or 42.4 Vac peak for a continuous, complex waveform.
Module connectors and test signal cables connected to them cannot be operator accessible. Cables and connectors are considered
inaccessible if a tool (e.g., screwdriver, wrench, socket, etc.) or a key (equipment in a locked cabinet) is required to gain access to them.
Additionally, the operator cannot have access to a conductive surface connected to any cable conductor (High, Low or Guard).
Assure the equipment under test has adequate insulation between the cable connections and any operator-accessible parts (doors,
covers, panels, shields, cases, cabinets, etc.). Verify there are multiple and sufficient protective means (rated for the voltages you are
applying) to assure the operator will NOT come into contact with any energized conductor even if one of the protective means fails to
work as intended. For example, the inner side of a case, cabinet, door, cover or panel can be covered with an insulating material as well
as routing the test cables to the module's front panel connectors through non-conductive, flexible conduit such as that used in electrical
power distribution.
