must remain fitted at all times in the bottom part of the enclosure.
The EE310 enclosure must be tightly closed during operation. An open enclosure corresponds to IP00
and exposes components carrying dangerous voltage. Any work (maintenance for instance) on the
device may be performed by qualified staff only.
AM2 for use in NFPA 79 application only.
1.2.3. Integrated power supply 100...240 V AC (option AM3, AM5)
