CMC 356 Reference Manual
10
• Before connecting and disconnecting test objects, verify that all outputs
have been turned off. Never connect or disconnect a test object while the
outputs are active.
• When disconnecting power supply cables or test leads, always start from
the device feeding the power or signal.
• All sockets on the front panel are to be considered dangerous with
working voltages up to 300 V
rms
. Only use cables that meet these
respective requirements to connect to the equipment.
• Red Signal Light :
If the voltage on any of the four voltage outputs or on the "AUX DC"
output exceeds 42 V, the associated signal light lights up.
• Do not insert objects (e.g., screwdrivers, etc.) into the sockets or into the
ventilation slots.
• Do not operate the CMC 356 under wet or moist conditions
(condensation).
• Do not operate the CMC 356 when explosive gas or vapors are present.
• Connect only external devices to the CMC 356 interfaces "USB", “ETH”,
"LL out" and "ext. Interf." that meet the requirements for SELV equipment
(SELV = S
afety Extra Low Voltage) according to EN 60950 or IEC
60950.
• For applications drawing DC current: The load may not exceed 3 mH
because of dangerous feedback current.
• When setting up the CMC 356, make sure that the air slots on the back,
top, and bottom of the test set remain unobstructed.
• Voltages up to 1 kV can be present inside the CMC 356. Therefore,
opening the CMC 356 is only permitted by qualified experts either at the
factory or at certified external repair centers.
•If the CMC 356 is opened by the customer, all guarantees are
invalidated.
• CMC 356 Ethernet functionality (see section 5.2.2, "Ethernet Ports ETH1
and ETH2" on page 35):
- It is a product of laser class 1 (EN 60825, IEC 60825).
- Connect ETH1 only to Ethernet ports.
•If the CMC 356 seems to be functioning improperly, please contact the
OMICRON Technical Support (→ “Support,” page 155).
