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.
