Connecting to mains outlet
If the mains outlet, mains cable, instrument's case or acces-
sories are damaged, do not connect the REVEXmax to the
mains outlet!
If Idir and Idif is being measured, use the grounded mains
outlet only to supply the instrument!
The REVEXmax can only be powered from 230 V / 50 Hz, which is protected
with a fuse or circuit breaker with a maximum rating of 16 A. The instrument is
automatically switched on after plugging into the mains outlet. Disconnect any
DUT while connecting/disconnecting the REVEXmax to/from the mains outlet!
The REVEXmax automatically tests the protective PE (ground) pin
of the mains outlet. If the PE connection is inadequate, then the mes-
sage (PE error) is displayed.
In order to check the proper PE connection to a mains outlet, the
REVEXmax generates a continuous current of ca. 1.5 mA / 50 Hz to
the PE conductor. This test current can activate the insulation moni-
toring device in IT systems.
If the REVEXmax is connected to an IT earthing system, it is possible
to measure – e.g. Rpe, Riso and Ialt.
If dangerous contact voltage arises on the PE, then the (PE error)
indicator lights up when the operator presses the key [TEST]. If op-
erator presses the [TEST] key after this, the measurement will not
start.
WARNING
If the test result for the ground pin of the mains outlet is
unsatisfactory (in TT or TN systems), the outlet must be
repaired before you plug in the REVEXmax to the outlet
again!
