Rule 3:
Fixing the cable shielding
•
Ensure proper fixation of the cable shielding.
•
Always use shielded data cables. Always connect both ends of the data cable shielding to ground on a large
area.
•
Keep unshielded cable ends as short as possible.
•
Always use metal/metalized connector housings only for shielded data cables.
•
Shields of load cells must be connected to the pin ‘Shield’ of the load cell connector of the eNod4 or, in case of
junction box, directly on the body of this one.
Rule 4:
Special EMC measures
•
For cabinet or enclosure lighting in the immediate range of your controller, use incandescent lamps or
interference suppressed fluorescent lamps.
Rule 5:
Homogeneous reference potential
•
Create a homogeneous reference potential and ground all electrical equipment.
Use sufficiently dimensioned equipotential bonding conductors if potential differences exist or are expected between
your system components.
Equipotential bonding is absolutely mandatory for applications in hazardous areas.
4.2
Power supply connection
On the front panel a green light
‘PWR’
, (D7) indicates if power is connected.
4.3
Load-cell wiring

4 wires load-cell
: jumpers in place (by default at delivery).
•
6 wires load-cell:
jumpers removed
4/ 6 wire jumper
fils
ON: 4 wires
OFF: 6 wires
