Wiring
Caution
• Please use an isolated Power supply and turn off the Power before any wiring operation
is performed.
• Input and Output cables should not be run through the same multi core cable or share
the same wire.
• Input cable (from sensor to AL2-2PT-ADP) must be less than 10m (32'81'') and the
output cable length must be less than 3m (9'10").
• The wire should be used as a single cable or the multi core wires (can be used with a
crimp terminal) should be carefully twisted together.
Do not connect a soldered wire end to the AL2-2PT-ADP.
• To avoid damaging the wire, tighten to a torque of 0.5 ~ 0.6 N⋅m.
• The AL2-2PT-ADP should be adjusted for offset and gain purposes, therefore, turn off
the Power before performing the adjustment wiring.
