4.2 Ensuring admissibility of the peripheral unit
If a peripheral unit needs to be connected, its RS232 interface must also be intrinsically safe
and approved to maintain the intrinsic safety.
• Ensure that the electrical limiting values of the peripheral match the limiting values printed
on the scale next to the socket.
If this is not the case, install an approved barrier, e.g. MTL 7061 Pac or 7161 Pac.
4.3 Attaching peripheral unit
• Connect the cable from the peripheral
device to the 9-pin I/O socket (3) of the
scale. Fix all connectors by tightening
screws.
