Special requirements:
The output current circuits are designed such that they can be
connected to either intrinsically safe or non-intrinsically safe current
circuits. However, intrinsically safe and non-intrinsically safe circuits
must not be mixed or combined.
The rated voltage of non-intrinsically safe current circuits is:
- for ATEX and GOST versions U m = 60 V
- for FM and CSA versions U m = 90 V (XP, NI, DIP).
•
Make sure that the cover of the power terminal box is always
closed properly. When using the device with intrinsically safe
output current circuits it is permissible to open the terminal box.
•
It is recommended to use the enclosed cable glands for the
output current circuits, according the type of explosion protection:
intrinsically safe = blue; non-intrinsically safe = black.

•
The flowmeter sensor and the transmitter housing must be
connected to an equipotential bonding system. When using
intrinsically safe current outputs proper equipotential bonding
must be ensured along the current circuits.
•
Make sure that the measuring pipe materials are resistant to
possible corrosive substances in the measuring medium. This is
the user's responsibility.

The values indicated here are taken from the respective approval
certificates. Always observe the specifications and supplements in
the approvals (ATEX, FM, CSA, GOST Russia).
