Field wiring
Please follow the instructions below:
▪
Field wiring must comply with local regulations and standards in force.
▪
DALEMANS recommend using colour coded cable with solid wires.
▪
Use a shielded or a screened twisted pair cable.
▪
The acceptable cross sectional area of the cable is 0.5 mm².
▪
The maximum cable length should not exceed 1000 m.
▪
The overall cable diameter must be within the range given below.
▪
Pass the cable through the gland to the desired position, then tighten the seal nut by hand
until resistance is felt (when the seal contacts the cable). Tighten with a spanner one
further turn.

Always ensure that the electrical requirements of the DAT 420 gas detector meet
the capability of the associated control unit or PLC (see "Specifications").
