ATEX Type n
Type 3661
Special Conditions for Safe Use
The Type 3661 has an IP44 ingress protection: it is
only intended to be installed in an area where a
convenient protection is ensured against the entry of
solid foreign bodies and liquids which may decrease
the safety.
Refer to table 4 for additional approval information
and figure 30 for the ATEX approvals nameplate.

Conditions of Certification
1. It is a condition of certification that the following
parameters are taken into consideration during
installation when the equipment is used as an Ex ia
apparatus:
Input Parameters
Maximum Input Voltage U
Maximum Input Current I
Maximum Internal Capacitance C
Maximum Internal Inductance L
2. It is a condition of safe use that the input voltage
does not exceed 32 Volts when the equipment is
used as an Ex n apparatus.
3. It is a condition of safe use that the equipment
shall be mounted such that the exhaust vents will be
self-draining.
4. It is a condition of safe use that the cable gland or
conduit adaptor with an ingress protection rating of
IP54 must be used in the conduit entry in order to
maintain the IP rating of the enclosure.
5. It is a condition of safe use that the irrelevant
explosion protection marking codes on the
certification label are permanently scribed off upon
completion of commissioning.
Refer to table 5 for additional approval information,
and figure 31 for the SAA approvals nameplate.
