Special Conditions for Safe Use:

1. The permitted ambient temperature range for the PD685 is -40°C to +75°C (-40°F to 167°F).
2. Use suitably certified and dimensioned cable entry device and/or plug. The equipment shall be installed such that the supply cable is protected from mechanical damage. The cable shall not be subjected to tension or torque.
3. Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore, the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. This is particularly important if the equipment is installed in a zone 0 location. In addition, the equipment shall only be cleaned with a damp cloth.
4. The cable entry into the enclosure shall be by means of conduit or cable gland and shall provide a minimum degree of protection of IP5X.

Year of Construction: This information is contained within the serial number with the first four digits representing the year and month in the YYMM format.
For European Community: The PD685 must be installed in accordance with the Essential Health & Safety Requirements of Directive 2014/34/EU, the product certificates CML 17ATEX2113X and IECEx CML 17.0052X, and the product manual. All controls and wiring connectors are accessed by opening the enclosure. To access electrical connectors, remove the enclosure cover, unscrew the two captive screws that fasten the printed circuit board, and remove the printed circuit board from the enclosure.
