Preconditions for safe operation of the
positioner
DANGER
Risk of explosion due to hot parts
Hot parts inside the device pose an explosion hazard.
• Never open the device immediately after switch-off.
• A waiting time of at least four minutes should be observed
before opening the device.
When using in hazardous areas, observe the following points:
• Observe the specification and special conditions
applicable for the device in accordance with the relevant
valid certificate.
• Manipulation of the device in any form by the user is not
permitted. Only the manufacturer or an explosion
protection specialist may modify the device
• The IP 65 / NEMA 4x IP rating is only achieved if the
splash guard is screwed in place. Operating the unit
without splash guard cap is prohibited.
• The device may only be operated using instrument air
that is free from oil, water and dust. The use of
flammable gas, oxygen, or oxygen-enriched gas is not
permitted.
Cable gland
Limited temperature range of the M20 × 1.5 plastic cable gland
for explosion protection variants.
The permissible ambient temperature range of the cable gland is
− 20 to 80 °C ( − 4 to 176 °F). When using the cable gland, make
sure that the ambient temperature is within this range. The
cable gland must be installed in the housing with a tightening
torque of 3.8 Nm. When installing the connection of the cable
gland and cable, check for tightness to ensure that the required
IP rating is met.
