2.5 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. The device's protection level
"ia" is lowered to protection level "ib" if fail-safe circuits are connected with protection level
"ib".
"Limited energy" type of protection ic/nL (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.
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.

Note
National regulations
Be sure to observe the regulations valid and relevant in your country.
Note
To improve the interference immunity:
Lay signal cables separately from cables with voltages > 60 V.
Use cables with twisted wires.
Avoid getting too close to large electrical systems or use shielded cables.
Use shielded cable to guarantee the full specification according to PROFIBUS PA or
FOUNDATION Fieldbus.
Use only cable entries and covers that are approved for the relevant use.
At an ambient temperature T ≥ 60 °C, use heat-resistant cables approved for an ambient
temperature of at least 20 K higher.
Use cables with wires that have a maximum cross-sectional area of 2.5 mm
