Safety Information The warning symbol on the device (exclamation point in triangle) means: Observe instructions! Warning! Protection against electric shock For applications with high working voltages, take measures to prevent accidental contact and make sure that there is sufficient distance or insulation between adjacent devices! Caution! Be sure to take protective measures against electrostatic discharge... - Page 3 Warning! EXPLOSION HAZARD Do not connect/disconnect equipment unless power has been removed or the area is known to be non-hazardous. Warning! EXPLOSION HAZARD Substitution of components may impair suitability for Class I, Division 2. Conditions for safe use (Haz. Loc.) For the use in hazardous locations, this equipment is to be installed into suitable enclosure, providing a degree of protection not less than IP 54.
- Page 4 Intended Use The special models P 27000-S007 universal isolators are used for galvanic isolation and conversion of input signals from 0 ... ±10 V to output signals from 0 ... ±20 mA. Signal transmission is linear. By means of the broad-range mains adapter, the units can be powered by voltages from 20 to 253 V AC/DC.
