Mettler Toledo IND500x Installationsanleitung Seite 46

These instructions describe how to connect the terminal's end of the intrinsically safe interface cable. Refer to
the installation manual of the other device used for details on connecting the opposite end of the cable.
Depending upon the country of installation, special cable protection such as conduit seals may be required.
Refer to the control drawing, the approval certificates and local regulations to determine what is required.
1 Make certain that power is removed from the terminal.
2 On the harsh enclosure, feed the cables through the correct cable gland (identified in [Connections
Page 12]) until the wires reach the I.S. serial interface board (approximately 90 mm – 3.5 in.). The COM5
cable should enter through the cable gland closest to the corner of the enclosure, and the COM4 cable
should enter through the cable gland beside the COM5 gland. Keep the internal wires as short as practical
and make sure they do not contact any other wiring. Some typical wiring schemes are shown in [I.S. Active
Current Loop Interface Page 38], [I.S. Active Current Loop Interface Page 38] and [I.S. Active Current
Loop Interface Page 38] below.
3 On the harsh enclosure terminal, after all the cables have been connected, tighten the compression nuts on
the cable glands to secure the cables.
