Supply voltage
The supply voltage is connected to the device casing through protective
elements exclusively.
Relevant for use in explosion hazard areas (Hazardous
Locations, Class I, Division 2)
When using the EAGLE40-03 devices as industrial control equipment the
following restrictions apply:
This equipment is suitable for use in Class I, Division 2, Groups A, B, C,
D – OR non-hazardous locations, if labeled “FOR USE IN HAZARDOUS
LOCATIONS”.
This device is an open-type device that is to be installed in an enclosure
suitable for the environment such that the device is only accessible with
the use of a tool.
All
of the following requirements are complied with:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1 or IEC/EN 62368-1.
Table 1:
General requirements for connecting electrical wires
All
of the following requirements are complied with:
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1 or IEC/EN 62368-1.
The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
See “Technical data” on page 40.
The cross-section of the ground conductor is the same size as or bigger than the cross-
section of the power supply cables.

Requirements for connecting the signal contact
Device variant
Requirements
All variants
All
of the following requirements are complied with:
The supply voltage corresponds to the voltage specified on the type
plate of the device.
The power supply complies with the requirements as per NEC Class 2.
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device (for
example, a switch or a plug). This disconnecting device is clearly
identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
The cross-section of the ground conductor is the same size as or
bigger than the cross-section of the power supply cables.
Relevant for North America:
The power cords are suitable for ambient air temperatures of at least
+167 °F (+75 °C). The power cord wires are made of copper.
