Revenue approval settings
• The access to the programming parameters via front key pad and/or serial communication ports is locked.
• The front key pad (up and down keys) allows the displaying of the variables only,
while the communication ports allows the transmission of the variables only.
• A proper “instrument settings” form must be filled up by the user before equipment
supplying.
• WM5-96 is supplied with the desired modules plugged and sealed in the proper slots.
• WM5-96 fulfils:
the ANSI/IEEE C12.20-1998 requirements;
the CAN3-C17-M84 requirements;
and can be certified according to:
C12.20-1998, class 0.5 (independent labs);
AE-0924 Industry Canada Approval.
In this case there are 2 base configurations:
1. display module + measuring input module
AV5 3 + power supply module H.
2. display module + measuring input module
AV6 3 + power supply module H.

Figure A
The sign of measured quantity and output quantity remains the same. The output
quantity is proportional to the
measured quantity.

The sign of measured quantity and output quantity remains the same. With the
measured quantity being

already has the value
Y1 = 0.2 Y2.

NOTE: In case of fault of first insulation the current from the measuring inputs to the ground is lower than 2 mA.
(*) The given insulation is granted among outputs plugged in different slots. The modules equipped with two or four outputs
have therefore non insulation among the outputs. (**) Insulation between the 2 outputs of the same module is 200V for 1 min.
