2. Safety Summary
CAUTION: Failure to properly ground the cable/device under test prior
to connecting it to the front panel connector, either directly or indirectly,
could result in damage to the sampling electronics and will void the War-
ranty.
2.6. Fuses
There are no external fuses or breakers accessible to the user. However, there are two internal
automatic thermal breakers that disconnect the power from the charger and battery to the rest
of the system. These thermal breakers make an audible click when they actuate, and the
CT100B turns off. One of the circuit breakers automatically resets after time. When this
breaker cools, the CT100B can be restarted, but the CT100B should be serviced by qualified
personnel. There is also an internal breaker on the power board. If tripped, this breaker must
be reset manually and the instrument should be serviced by qualified personnel.
CAUTION: If the thermal breakers trip, the instrument should be evalu-
ated by qualified service personnel for maintenance.
2.7. AC Power Source
The CT100B is intended to operate only from a 120 VAC or 240 VAC RMS power source using
the CE- and UL-approved 24 VDC external power supply/adapter (pn: CT100-AC-PS)
provided with the instrument.
WARNING: Only use the power cord supplied with the instrument, and
then only if the cord is in good condition. Refer all maintenance regarding
the power supply or power cord to qualified service personnel.
CAUTION: Use of any power source other than the supplied external
power adapter(s) could damage the instrument and may void the War-
ranty. Use only MOHR-approved accessories.
WARNING: To reduce the risk of electric shock, disconnect all external
cables before connecting the 24 VDC external power supply.
