Figure 5-46 AM600-4PT module wiring
NOTE
◆
*1 Use shielded cables;
◆
*2 If two-wire wiring is used
,
the INB and Inb channels need to be shorted
,
and the cable
resistance a󶍽ects the measurement;
◆
*3 Use cables with small wire resistance and without resistance di󶍽erence between the three
wires;
◆
*4 The module should be mounted on a well-grounded metal bracket
,
and ensure that the metal
shrapnel at the bottom of the module is in good contact with the bracket.
