4. Safety regulations

4.1 general safety regulations
Use of the explosion-proof Ex-DT 12 assumes that the
operator complies with conventional safety regulations and
has reas the certificate in order to eliminate faulty opera-
tion of the unit. The following additional safety regulations
must also be observed:
- In the ex-area, take measurements only on idle circuits.
- The device must not be opened within the ex-area.
- The batteries must only be changed outside the ex-area.
- Additional or spare batteries must not be carried in the
ex-area.
- Only the batteries listed in the Owner's Manual wmust be
used, as these batteries are typeapproved.
- Only accessories approved by ecom instruments GmbH
may be used.
- If the cable insulation or test probe become damaged,
the device must be taken out of operation immediately.
- The maximum permitted ambient temperatures wmust
be respected.
- It must be ensured that the unit is not taken into zone 0.
4.2 special safety regulations
In order to avoid injury, it is advisable to fit the supplied
protective caps over the test probes when the device is not
in use or being stored.
4.3 use on electrical circuits outside the ex-area
When operating/using the device on electrical circuits
outside the ex-area, ensure that the permitted maximum
values are not exceeded (responsibility of the user).
