1.1 Special Conditions for Safe Use



Use the calibrator only as described in this technical manual.



The battery should only be charged in a safe area, using the supplied charger. To
prevent explosion or fire, use only the battery BT507-IS and the charger CG507-IS
specified by Presys.



Never replace the battery in hazardous areas.



Do not use the serial communication port in hazardous atmospheres.



The calibrator aluminum metal enclosure is protected by a leather bag (BC507-IS)
that should always be used when in hazardous areas.



The intrinsic safety of the instrument is only valid for the connections shown in this
manual, respecting the intrinsically safe input and output parameters. The entity
parameters and connections are illustrated in the items "3.4, 3.5 and 3.6 -
Operation".



To prevent damage to the instrument and validate the Ex certification, never apply
a voltage greater than 30 V between the terminals and the metal enclosure of the
instrument.



Never open the calibrator enclosure. The opening of the enclosure may void the Ex
certification.



Do not use tools that may cause spark in the calibrator; this practice can cause
explosion.



Never do any maintenance on calibrator; the components used are specified and
cannot be changed.



Never use the Calibrator in an area close to explosive dust.
