What are the control power input requirements?
120 to 300 V DC ± 10%
50/60 Hz ± 10% : 90 to 415 V ± 10%400 Hz: 90 to 120 V ± 10%
    Meter only: 18VA max at 415V AC, 6W at 300V DC
    Fully optioned Meter: 36 VA max at 415V AC, 17W at 300V DC

What is the rating of the current inputs?
Nominal 5 A (Class 0.2S) or 1 A (Class 0.5S)
Measured current: 50 mA to 10 A
Starting current: 5 mA
Withstand: 20 A continuous, 50 A @10 sec/hr, 500 @ 1 sec/hr
Impedance: 0.3 mΩ
Burden: 0.024 VA at 10 A

What are the voltage inputs rated at?
Measured voltage: 57 to 400 V L-N / 100 to 690 V L-L (Wye) or 100 to 600 V L-L (Delta or Wye with unearthed neutral)
Frequency: 50/60 Hz ± 15%,
400 Hz ± 10%
Overload: 600 V L-N or
1035 V L-L

What are the options to connect the PM8000 via RS485?
The PM8000 can be connected via RS485 2 wire. The remote display does not have the option to connect RS485 4 wire as the PM800 does.
in order to communicate RS485 4-wire, a 2 to 4 wire converter needs to be used.

What are the maximum number of digital and analog inputs on the PM8000 series?
27 Digital inputs
16 Analog inputs
