Measures
In the interests of safety, the following precautions must be observed:
WARNING
"Intrinsic safety" type of protection
Connect the device only to certified, intrinsically safe circuits. These circuits must comply
with the technical data specified on the nameplate or in the certificates and approvals.
Should these circuits not match the details given in the certificates and approvals, then the
safety required for the approval can no longer be guaranteed.
"Device connection through intrinsic safety" type of protection ic (Zone 2)
Devices of the protection type "limited energy" can be connected and disconnected during
operation.
"Non-sparking" type of protection nA (Zone 2)
Devices of the protection type "non-sparking" may only be connected and disconnected
when in a powered-down state.
WARNING
Electrostatic-sensitive devices in potentially explosive environment
It is essential to avoid electrostatic charges. These could develop e.g. when cleaning the
plastic enclosure with a dry cloth.
CAUTION
Modules susceptible to electrical discharge
The device contains modules susceptible to electrical discharge. Modules susceptible to
electrical discharge can be destroyed by voltages that fall far below the limits of human
perception. These voltages even occur if you touch a component part or electrical
connections of a module without being electrostatically discharged. The damage to a
module caused by overvoltage cannot normally be detected immediately, it only becomes
apparent after a longer period of operating time has elapsed.
