1.1 Location
1.1.1 IP50 Rated Units (SMD23E2-M12 and SMD24E2-M12)
SMD23E2 and SMD24E2 units that are IP50 rated are suitable for use in an industrial environment that meet
the following criteria:

Only non-conductive pollutants normally exist in the environment, but an occasional temporary con-
ductivity caused by condensation is expected.

Transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insu-
lation.
These criteria are equivalent to the Pollution Degree 2 and Over Voltage Category II designations of the Inter-
national Electrotechnical Commission (IEC).
1.1.2 IP64 Rated Units (SMD23E2-M12S and SMD24E2-M12S)
SMD23E2 and SMD24E2 units that are IP64 rated are suitable for use in an industrial environment that meet
the following criteria:

Conductive pollution or dry nonconductive pollution, which could become conductive due to expected
condensation.

Transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insu-
lation.
These criteria are equivalent to the Pollution Degree 3 and Over Voltage Category II designations of the Inter-
national Electrotechnical Commission (IEC).
1.1.3 IP65/67 Rated Units (SMD23E2-M12P and SMD24E2-M12P)
SMD23E2 and SMD24E2 units that are IP67 rated are suitable for use in an industrial environment that meet
the following criteria:

Continuous conductivity occurs due to conductive dust, rain, or other wet conditions.

Transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insu-
lation.
These criteria are equivalent to the Pollution Degree 4 and Over Voltage Category II designations of the Inter-
national Electrotechnical Commission (IEC).
1.2 Safe Handling Guidelines
1.2.1 Prevent Electrostatic Damage
Electrostatic discharge can damage the SMD23E2 or SMD24E2 units. Follow these
guidelines when handling the unit.
1) Touch a grounded object to discharge static potential before handling the unit.
2) Work in a static-safe environment whenever possible.
3) Wear an approved wrist-strap grounding device.
4) Do not touch the pins of the network connectors or I/O connector.
5) Do not disassemble the unit
6) Store the unit in its shipping box when it is not in use.
