Direct connection with powering the device:
The - wire of the current outputs of external measuring sys-
tems need be directly connected to the current inputs (X10) of the MIQ/IC2 module. The + wire of the current
outputs of external measuring systems need be directly connected to the + 24V power supply (X8) of the MIQ/
IC2 module. A jumper cable needs to be ran from the - current inputs (X9) to the - 24V power supply (X7) of the
MIQ/IC2 to complete the loop.
Connect the cable to the device or an isolator.

Direct connection without powering the device:
The current outputs of external measuring systems can be
directly connected to the current inputs of the MIQ/IC2 module. If the connection data of the external meter is
suitable.
Apply power to device.
Keep in mind the following information when
setting up the MIQ/IC2 Module and third party
devices.
IQSN Power Consumption: The power
consumption is 0.2 watts plus 2.2 watts per
connected power supply/isolator.
Loop Powered Devices: The 24V power supply
in the MIQ/IC2 is rated for 240mA. If powering
two devices make sure the current draw of
the entire 24V loop (the devices and isolators)
doesn’t exceed 240mA.
