Danger!
Explosion hazard in Zone 2 when operating powered Gateway
If the Gateway is installed in Zone 2 and connected to power, there is an explosion hazard
when operating DIP switches, buttons or connecting/disconnecting cables.
The operation of DIP switches/buttons and the connection/disconnection of any cables in
Zone 2 is only permitted in the absence of a hazardous atmosphere or if the device is
disconnected from power!
Danger!
Electrostatic discharge hazard
The device contains non-conductive plastic parts. Care must be taken when operating the
installed device because of possible electrostatic charges. Electrostatic charged surfaces
may cause an ignition spark.
Electrostatic charges must be avoided. For example, do not rub the device and never clean
plastic surfaces with a dry cloth. Always use a damp cloth instead.
