EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS

Bus and Port Connections

Overview
WARNING
Risk of electric shock or equipment damage!
Do not touch any live parts in the cabinet!
►
Disconnect the power supply before making connections
►
to or removing connections from terminals of the
EAGLEHAWK NX controller or Panel Bus I/O modules.
Do not reconnect the power supply until you have
►
completed installation.
Due to the risk of short-circuiting (see Fig. 23), it is
►
strongly recommended that the EAGLEHAWK NX con-
troller be supplied with power from a dedicated trans-
former. However, if the EAGLEHAWK NX controller is to
be supplied by the same transformer powering other con-
trollers or devices (e.g., the PW M-Bus Adapter), care
must be taken to ensure that correct polarity is observed.
Observe the rules regarding electrostatic discharge.
