EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS

WIRING AND SET-UP

General Safety Considerations

• All wiring must comply with applicable electrical codes and
ordinances, including VDE, National Electric Code (NEC)
or equivalent, and any local regulations must be observed.
Refer to job or manufacturer's drawings for details. Local
wiring guidelines (e.g., IEC 364-6-61 or VDE 0100) may
take precedence over recommendations provided here.
• Electrical work should be carried out by a qualified
electrician.
• Electrical connections must be made at terminal blocks.
• For Europe, only: To comply with CE requirements,
devices with a voltage in the range of 50 ... 1000 VAC or
75 ... 1500 VDC which are not provided with a supply cord
and plug or with other means for disconnection from the
supply having a contact separation of at least 3 mm in all
poles must have the means for disconnection
incorporated in the fixed wiring.
WARNING
Risk of electric shock or equipment damage!
Observe precautions for handling electrostatic sensitive
►
devices.
Do not touch any live parts in the cabinet.
►
Do not open the controller housing.
►
Disconnect the power supply before making connections to
►
or removing connections from terminals of the
EAGLEHAWK NX controller and devices wired to it.
Do not use spare terminals as wiring support points.
►
To prevent risk of injury due to electrical shock and/or
►
damage to the device due to short-circuiting, low-voltage
and high-voltage lines must be kept separate from one
another.
All terminals are protected (up to 24 VAC) against short-
►
circuiting and incorrect wiring (unless the 3-position slide
switch is set to "END," in which case the terminals of the
RS485-1 bus [24, 25, and 26] have no such protection).
Higher voltages may damage the device.
Do not reconnect the power supply until you have
►
completed the installation.
Fusing Specifications
System Fusing
We recommend that the system be equipped with an external
fuse.
Fusing of Active Field Devices
F2 (depends upon given load).

Lightning Protection

Please contact your local Honeywell representative for
information on lightning protection.

Wiring Terminals

The EAGLEHAWK NX is equipped with push-in terminal
plugs.
EN1Z-1039GE51 R1218
Fig. 22. Inserting/removing wires from push-in terminals
NOTE: With solid conductors, ferrules are prohibited.
NOTE: Use only one conductor per push-in terminal.
NOTE: If, nevertheless, two stranded wires are to be
connected to a single push-in terminal, twin wire end
ferrules must be used.
