use of AP2600 in an explosive area

[mohamadzawawi.salleh]

Hi, I have requirement for wireless access in an explosive area. Currently i already have a controller based AP2600. My plan is to install AP2600 outside the explosive area and install the antennas that came with AP2600 in the explosive area by using longer antenna cable. Is this approach comply to EX 1 zone safety requirement? Kind regards Zawawi

I believe only the AP 1550 is rated for "Ex nA".

Avoid extending the antenna cables it at all possible.
If you choose to use longer cables, be aware there is significant loss (attenuation) in cable and different types of cable has different loss ratings. This loss affects both the ability to receive (decode) the signal as well as reducing the transmitter power as well.
Additional cable and RF connectors also introduce potential points of failure and reduce overall MTBF. So use additional cable only when needed. Consider relocating the device closer to the user or antenna source.
