2 Safety and Regulatory Information
Ground The System
To minimize shock hazard, the instrument chassis and cover
must be connected to an electrical protective earth ground. The
instrument must be connected to the ac power mains through a
grounded power cable, with the ground wire firmly connected
to an electrical ground (safety ground) at the power outlet. Any
interruption of the protective (grounding) conductor or
disconnection of the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
Fuses
Use only fuses with the required rated current, voltage, and
specified type (normal blow, time delay). Do not use repaired
fuses or short-circuited fuse holders. To do so could cause a
shock or fire hazard.
For AC inlet fuse, use only 5A/250VAC fuse with Time-Lag and
Low Breaking capacity. For other fuse ratings, refer Table 3-11.
Operator Safety Information
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 a conductive
surface connected to any cable conductor (High, Low or Guard).
In order to avoid electrical hazards, all system internal fuses must
be replaced by trained and qualified personnel.
M
Module connectors and Test Signal cables connected to them
cannot be operator accessible.
Assure the equipment under test has adequate insulation
between the cable connections and any operator-accessible parts
(doors, covers, panels shields, cases, cabinets, etc.)
