4.10 Grounding
Note
The grounding connections, described in this section, are examples. Adapt these examples
to the installation situation on-site. Observe local regulations regarding grounding and
installation of electrical equipment. The transition resistance between housing and
protective ground must be <100 m
Ω measured at 40 A. The connection cable must be
colored green or green/yellow.
The AMS Asset Monitor has a grounding terminal at the bottom. The grounding terminals
for the shields of the field wiring cables and the two additional internal grounding
terminals in the lower left and right corner are internally connected to this grounding
terminal.
A ground connection between the housing of the AMS Asset Monitor and protective
ground is at least required if field signals with up to 250 V AC are connected. The
KL4502X1-MA1 CHARM Relay Output Terminal Block may have hazardous live voltages on
its output terminals. This terminal block is capable to switch field power of up to 250 V AC.
The minimum required grounding connection is a connection between the labeled
internal grounding terminal and protective ground.
