Wiring Advice
This meter uses detachable screw terminal connectors. Refer to the wiring
diagram on the following page for the correct positioning of each wire.
The conductors you use must be suitable for the meter’s temperature, current
and voltage rating, which is broadly described as follows:-
Cable Temperature Rating
All cables must be rated for operation up to 90C continuous.
Cable gauge
The connectors on this instrument can accept conductors up to 1.5mm
2
c.s.a.
The minimum cross sectional area shall be 0.5mm
2
Cable insulation voltage rating
Cables shall have an insulation voltage rating of at least 380V continuous.
Wire preparation:
We recommend multi-strand wire, because it withstands vibration better than
single strand cable. Pull the wire firmly after you make the connection to confirm
it is tight.
Use screened cable for all signal and control wiring and connect the screen to
earth at the destination end only. Route signal cabling away from power cabling
and relay switching cabling, to avoid electrical noise interference.
