NOTE Other terminal blocks that are not described (marked "UNUSED") do not affect

the operation of expander and are not used.

POWER

The expander is powered via an external power supply.

Use any 12V or 24V power supply and connect it to the +/- inputs on the device.

ATTENTION The power supply should have an output current limit of 8A and should

meet the requirements of AS ISO 7240.4. The AC and DC inputs are used for moni-

toring the state of the external power supply (this option should be enabled in EK-

WL8-TRH menu

The expander measures the voltage levels between "-" and each of the AC/DC in-

puts, a fault event will be generated if the voltage drops below 10.5 V. These inputs

can be directly connected to the open collector outputs on the power supply. In other

cases, you will need to provide power to these inputs through a normally closed fault

relay on the power supply. The AC and DC input monitoring can be disabled via the

translator menu.

Main and Backup power monitor modes should be set "ON"
