WARNING
!
EXPLOSION HAZARD - In Class I Division 2
applications, an external, Class 2 power supply must
be used. The DC Power Source selector switch on
the ENI must be set to EXTERNAL before connecting
the power supply to the ENI.
IMPORTANT
•
In non-hazardous locations, external power is not
required. Some devices (such as a MicroLogix
controller) provide power to the ENI via a cable
connected to ENI port 2. Be sure to set the DC
power source selector switch to match your
particular configuration, CABLE or EXTERNAL.
•
Always connect the CHS GND (chassis ground)
terminal to the nearest earth ground. This
connection must be made whether or not an
external 24V dc supply is used.
