POINTRAC 31 • 8/16 mA/HART - four-wire

39411-EN-131119

Information:

The terminal blocks are pluggable and can be detached from the

electronics. For this purpose loosen the two lateral locking levers of

the terminal block with a small screwdriver. When loosening the lock-

ing,theterminalblockisautomaticallysqueezedout.Itmustsnapin

place when re-inserted.
