RMO500 Safety Instructions, Designated Use
Operator Qualifications
• Testing with RMO500 should only be carried out by authorized and qualified
personnel.
• Personnel receiving training, instruction, direction or education on the RMO500
should remain under the constant supervision of an experienced operator while
working with the test set and the test object.
Safe Operation Procedures
• Hazardous voltages of up to 400V can occur inside RMO500. Therefore is not
permitted to open RMO500.
• Do not insert objects (e.g., screwdrivers, etc.) into the ventilation slots.
• Before putting RMO500 into operation, check the test set for visible damages.
• Do not operate RMO500 under wet or moist conditions (condensation).
• Do not operate RMO500 when explosive gas or vapors are present.
• The serial interface of RMO500 should only have external devices connected that
meet the requirements for SELV equipment according to EN 60950 or IEC 60950.
• When setting up RMO500, make sure that the air slots of the test set remain
unobstructed.
• If RMO500 is opened by the customer, all guarantees are invalidated.
• If RMO500 seems to be functioning improperly, please call the IBEKO POWER AB
(refer to section ”Manufacturer Contact Information”).
• Do not use RMO500 without the extra protective ground (PE) cable set connected.
Power Supply
• Supply RMO500 only from a power outlet that is equipped with protective ground .
• Instead of supplying RMO500 from phase – neutral (L1-N, A-N), it may also be
supplied from phase – phase (e.g., L1-L2; A-B). However, the voltage must not
exceed 240 V AC, please refer to section 8.1.
3 Designated Use
The Micro OhmMeter RMO500 is designed for measuring contact resistances of non-
inductive test objects used in the electric power industry or similar branches. It is
employed for resistance measurement during manufacturing, commissioning and
testing of:
ƒ
power circuit breakers,
ƒ interrupters,
ƒ bar installation,
ƒ cable splices,
ƒ
welded joints,
ƒ grounding.
Any other use of the RMO500 than the ones mentioned above is to be considered
improper and will not only invalidate all customer warranty claims but also exempt the
manufacturer from its liability for repair or exchange.
