instrument for the continuous monitoring of carbon
dioxide.
3.5 Approvals
3.5.1 ATEX, IECEx, UL, CSA
See a sample of approval label on the fold-out page. There is
also a printout of the approval label inside the shipping box of
the instrument.
3.5.2 Marking
The marking is reproduced on a separate piece of paper
shipped with the instrument.
Serial Number key: The third letter of the serial number
specifies the manufacturing year: M = 2019, N = 2020, P =
2021, R = 2022, S = 2023, T = 2024, U = 2025, W = 2026, X =
2027, Y = 2028, Z = 2029, etc. (Letters G, I, O, Q are omitted)
Example: Serial Number ARMB-0001: the third letter is M,
which means that the unit was manufactured in 2019.
4 Explosion proof (Ex d) installation
- without Docking Station
Obey the safety statements mentioned in 1.3 Mechanical
installation!
4.1 Mechanical installation without
Docking Station
The instrument can be mounted for measuring gases in
ambient air or inside of a duct/pipe.
1. Use M6 (1/4'') bolts with hex socket caps to mount the
enclosure to one of the following options.
Option
Mounting on a flat surface
Mounting on a pole
Mounting on a duct/pipe
4.2 Electrical installation without
docking station
For recommended tightening torques and admissible wire
specifications see 17.3 Cable specifications.
