Connect System Power
WARNING:
You can use PointMax I/O systems in environments with explosion risks, for example,
mining applications. You must consider additional factors with respect to power
connections in these situations, specifically when you can remove the system from a
cabinet. If your application requires the enclosure to deplete residual energy to
0.2 mJ the following steps are required in order to be compliant with the IEC/EN
60079-0 standard:
- Label the enclosure with: WARNING - AFTER DE-ENERGIZING, DELAY 5 MINUTES BEFORE OPENING.
- Wait at least 5 minutes after removal of power before opening the enclosure to access the PointMax I/O system.
There is no visual indication of when the 5 minutes have expired.
You must track
that time period.
- For mining applications, the entire PointMax I/O system must deplete residual energy before you can open an explosion-proof cabinet.
Some applications require that the installed controller to deplete its residual
stored energy to specific levels before transporting it into or out of your
application. This requirement can include other devices that also require a wait
time before removing them. See the documentation of those products for more
information.
