Safety
WARNING
Read this User’s Manual carefully and completely and follow
all instructions contained therein. If not, the use of the in-
strument may be dangerous for the operator, devices under
test or for the instrument!
If there is reason to believe that safe operation has become impossible,
put the instrument out of operation and secure it against any unin-
tended operation. Safe operation must be presumed to be no longer
possible, if:
•
The instrument does not operate properly any longer.
•
The instrument, cables, connectors, plugs or accessories exhibits
visible damages.
•
The instrument was stored in unfavourable conditions for a long
period.
•
The instrument was exposed to extraordinary stress caused by
transport.
WARNING
•
Make sure that the instrument, measuring cables and all other
accessories are in flawless condition, e.g. no damaged insulation,
no broken cables or plugs etc.
•
Make sure that the AC outlet is easily accessible. If some trou-
ble or malfunction occurs, immediately disconnect the MDtest
adaptor from the outlet.
•
If the equipment is used in a manner not specified by the manu-
facturer, the device’s protection may be compromised.
•
The instrument may only be powered from a 100
÷
140 V / 50 or
60 Hz grounded mains outlet, which is protected with a fuse or
circuit breaker with a maximum rating of 16 A.
•
Voltage 127 V / 50/60 Hz will be used in this manual hereinafter.
•
In order to check the proper PE connection to a mains outlet,
MDtest generates a continuous current of ca. 1.5 mA / 50 or
60 Hz to the PE conductor. This test current can activate the
insulation monitoring device in IT systems.
•
Only a trained, skilled person, who is familiar with hazardous
voltage operations, can handle the MDtest. Unexpected haz-
ardous voltages can occur on devices under test (dangerously
charged capacitors, etc.).
