Service, Support, and Safety Information
Ground the instrument or system
Fuses and Circuit Breakers
Refer to individual instrument manuals for detailed information on operator
accessible fuses.
WARNING
To minimize shock hazard, the instrument chassis and cover must be connected
to an electrical protective earth ground. The instrument and/or system 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.
WARNING
This is a Safety Class 1 Product (provided with a protective earthing ground
incorporated in the power cord). The mains plug shall be inserted only in a
socket outlet provided with a protective earth contact. Any interruption of the
protective conductor inside or outside of the products is likely to make the
product dangerous. Intentional interruption is prohibited (IEC 348 clauses 17.3.3
c and 17.3.4).
CAUTION
Always use the three-prong AC power cord supplied with this product. Failure to
ensure adequate earth grounding by not using this cord may cause product
damage.
CAUTION
The detachable power cord is the disconnecting device. It disconnects the mains
circuit from the mains supply before other parts of the instrument or system. The
instrument front panel switch is only a standby switch and is not a line switch.
WARNING
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.
WARNING
For continued protection against fire hazard, replace fuses and circuit breakers
only with the same type and ratings. The use of other fuses or circuit breakers or
materials is prohibited (IEC 348 clause 17.3.5.d).
WARNING
The premise wiring should have a system-dedicated circuit breaker in the mains
wiring for installation of the system.
