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 and screw tightness
The connectors on this instrument can accept conductors up to 16 gauge AWG / 1.5mm
c.s.a. The minimum cross sectional area shall be 22 gauge AWG / 0.5mm
terminals to 7.0 lb/in torque / 0.8 Nm torque.
Cable insulation voltage rating
Cables shall have an insulation voltage rating of at least 380V continuous.
Wire preparation:
Detachable
connectors
Terminal screwdiver - 3mm blade
No bare wires exposed
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.
