EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS

Power Supply

Powering EAGLEHAWK NX
Power is supplied via a removable terminal plug (attached to
terminals 1 and 2).
The power supply of the EAGLEHAWK NX controller must
conform to Safety Class II. To reduce overall current con-
sumption, the EAGLEHAWK NX can be powered by a switch
power supply (rather than by a transformer). See also Table 2
on pg. 3.
NOTE: Due to the risk of short-circuiting (see Fig. 23), it is
strongly recommended that the EAGLEHAWK NX
controller be supplied with power from a dedicated
transformer. However, if the EAGLEHAWK NX con-
troller is to be supplied by the same transformer
powering other controllers or devices (e.g., the PW
M-Bus Adapter), care must be taken to ensure that
correct polarity is observed.

Transformer Data
In Europe, if the EAGLEHAWK NX is powered by trans-
formers, then such transformers must be safety isolating
transformers conforming to IEC61558-2-6. In the U.S. and
Canada, if the EAGLEHAWK NX is powered by transformers,
then such transformers must be NEC Class-2 transformers.

RIN-APU24

The RIN-APU24 Uninterruptable Power Supply can be
directly wired to an EAGLEHAWK NX controller.
See RIN-APU24 Uninterruptable Power Supply – Mounting
Instructions (EN0B-0382GE51) for a detailed wiring diagram.
Powering Panel Bus I/O Modules and Field Devices
The EAGLEHAWK NX, Panel Bus I/O modules, and field
devices can be powered by either separate transformers (see
Fig. 25, and Fig. 26) or by the same transformer.
NOTE: Use a min. distance of 10 cm between power cables
and 0...10 V / sensor cables in order to prevent
signal disturbances on the 0...10 V / sensor cables.
See also section "Addressing Panel Bus I/O
Modules" on page 35.
