The AI has been tested to EN5
5024 Generic Immunity
Standard–Industrial Environment. This standard identifies a
series of tests requiring the equipment to perform to a particular
level during or after the execution of the tests. The three classes
of performance are defined by CC as follows:
Class A
— Normal operation, however, occasional
reconfigurations may occur or throughput reduced due to error
recovery algorithm by the ARCNET data link level protocol.
Class B
— Throughput reduced to zero and continuous
reconfigurations occur. Normal operation resumed after
offending signal removed.
Class C
— Complete loss of function. Unit resets and normal
operation restored without human intervention.
At no time did the AI fail to return to normal operation or
become unsafe during the execution of these tests.
A copy of the Declaration of Conformity is in the appendix.
2.3 Mounting the AI
2.4 Powering the AI
The AI requires either low voltage AC or DC power in order to
operate.
Consult the specifications for power requirements.
Power is provided to a four pin removable keyed connector and
there are several methods for providing power.
The
AI Series can be snap-mounted onto TS-35 DIN-rail using
the pre-attached DIN-rail clip. If the clip is removed, the unit
can be
panel mounted using the adjustable brackets affixed to
rear of the enclosure. (See the dimensional drawing in
Section 1.3 for details).
