Key points of engineering planning and maintenance
1. Coating selection
For G2 (moderate) or G3 (severe) corrosive environments, TK prefix three proof coating modules must be selected, in accordance with ISA-S71.04 standard.
2. Live plug and unplug (RIOP)
Normal area: allowed.
Dangerous Zone (Class I Div 2): Live insertion and removal are prohibited.
3. Fuse
The fuse of CIOM-A power module is internally welded and cannot be replaced.
Some modules of RIOM-A require external insurance (such as TC-FODA81 recommending 1.6A slow break).
4. Environmental specifications
Working temperature: 0~60 ℃ (CIOM-A), 0~55 ℃ (RIOM-A), some intrinsic safety modules -20~70 ℃.
Storage temperature: -40~85 ℃.
Relative humidity: 5-95% non condensing.
Vibration/impact: 5g/30g (CIOM-A), 2g/15g (RIOM-A).
5. Cabinet layout
The vertical spacing between CIOM-A racks is ≥ 203mm, and the horizontal spacing is ≥ 102mm.
The depth of the cabinet is ≥ 203mm.
