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.
• 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.
