Installation
Verification:
Verify that the instrument configuration is according to your order.
Aux. supply:
Connect terminals to correct voltage. See label on unit.
Measuring circuit:
Connect PE to ground and P to a phase (if it is a 3-phased network – connect to
any of the phases).
Warning:
If a high-voltage “MEGGER” is used, the SIM-2 must be disconnected at terminal “P”
before testing is carried out. Ignoring this may result in damage to the SIM-2.
Adjustment of the set point
When the selector on the front is placed in Test mode, the meter indication shows the set point
setting directly. Set point potentiometer on the rear side is used for changing value.
Remember to return the selector to normal mode after setting!
Set point test/control
During the first 10 seconds after power-up, the meter pointer shows the
actual set point setting and activates its relay.
