Panametrics flare.IQ Generation 2, Operation And Maintenance Manual

4.4  Replacing a DPU

4.4.1 Installation

The Advantech DPU mounts directly to the panel  

sheet metal.

To remove the controller

1.  Unplug the 24V dc power cable from DPU.
2.  Remove the ethernet cables from the controller.
3.  Loosen the upper and lower setscrews mounted  

on the controller. Slightly lift the module and  

take out the controller.

To install the controller

1.  Mount an upper screw on the panel. Hang the  

controller on the screw and align it with the panel’s  

lower screw hole.

2.  Mount a lower screw and tighten both screws to  

secure the controller.

3.  Connect the corresponding communication  

interface cables.

4.  Plug the system network cables into the Ethernet  

ports (LAN A and LAN B) of the controller.

5.  Plug the dual-24V dc power cable into the power  

input socket on the top of the controller.

CAUTION! 

Electronic controls contain static-sensitive 

parts. Observe the following precautions  

to prevent damage to these parts.  

Discharge body static before handling  

the control equipment.

Do not touch the components or connectors on electronic 

equipment with your hands.

4.5 Environment

4.5.1  Mounting location

Consider these requirements when selecting the  

mounting location:
•  adequate ventilation for cooling;
•  space for servicing and repair;
•  protection from direct exposure to water or to a 

condensation-prone environment; a cabinet with  

at least an IP52 rating;

•  protection from high-voltage or high-current devices,  

or devices which produce electromagnetic interference;

•  avoidance of vibration;
•  selection of a location that will provide an operating 

temperature range of 0°C to 40°C (32°F to 104°F) with  

less than 95% humidity (non-condensing).

4.7 Reliability

The failure rates of the 4 major hardware components 

(Advantech UNO 2271G DPU, GEAE ESWx Network switch, 

Phoenix Contact MINI-PS-100 power supply, Puls MLY10.241 

Dual redundancy module) are specified at an ambient 

temperature of 30°C or 40°C. Based on these specifications, 

the calculated mean time between failures (MTBF) for the 

flare.IQ Gen 2 system at 30°C ambient is 386,650 hours  

or 44.14 years.

4.8  Technical regulations 

and standards

The flare.IQ Gen 2 complies with IEC 61010-1:2010, AMD1:2016 

and additional national differences. It also bears the CE  

mark in compliance with the 2014/30/EU EMC and the 

2014/35/EU LVD directives. Please refer to the DoC at the  

end of this manual.
