Connecting the EA200 / EA400
Note: Make certain all wiring to be connected is passing through the opening in cen-
ter of mounting plate.
Note: All terminals must be connected to a Class 2 Power Limited Circuit
complying with the National Electric Code NFPA 70, Article 725.
Note: Where required, this equipment is to be isolated from the mains supply by a
limited power source as specified in EN60950.
EA200 / EA400 Connectors
Figure 6 shows and describes the functions of the EA200 / EA400 connectors.
Note: All connections to the EA200 / EA400 circuit board header connectors are
made using Terminal Block Adapters (supplied with the EA200 / EA400 and
with sensors; and available as an accessory item). To ease connection of
stripped wire ends to the adapters, the adapters can be removed from the cir-
cuit board header connectors. Connect stripped wire ends to the adapters as
follows:
• Remove the adapter from the circuit board by pulling the adapter up and off
of the circuit board header connector.
• Insert stripped wire ends into side of adapter. Secure the connections using
the set screws on the adapter. Check the connection by lightly pulling on
each connection.
• After connecting the wire ends to the adapter, align the adapter to the
header pins where connection is desired, and press the adapter fully onto
the header connector pins.
