    Installation and commissioning DANGER! Contact of parts under voltage is extremely dangerous! When installing or changing the meter, the conductor to which the meter is connected must be de-energized. • Remove the relevant back-up fuses, for two-sided supply on the mains side as well as on the generation side.
  • Page 10: Mounting An Connection

    Mounting an connection The meters are suitable for mounting in a 19″ racks. DANGER! Low voltage inputs are separated from hazardous live voltages only by basic insulation. Therefore the low voltage inputs should not be accessible under normal operational conditions. DANGER! Contact of parts under voltage is life endangering! S0-inputs are not potential-free.
