9.1.2 Mounting the expansion module
If the converter is ordered with 4 current outputs, the expansion module is already pre-mounted
inside the converter. If this option is ordered separately, the module shall be mounted inside the
converter following the instructions below.
How to get started:
• Make sure the converter to be used is switched off.
• Open the front and locate the expansion module connector.
• Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module.
• Mount the module into the box, be careful to fit all 34 pins into the socket.
• Fasten the three M2.5x5 screws.
• Connect the 4...20 mA loops to the screw terminals according to the table below.
• Switch on the power to the converter and check that the module identifies itself in the
converter menu.
i When correctly mounted, the module will identify itself as "4-20mA" in the converter start-
up display and under "Exp.module" in the converter "Settings" menu.
• Configure the sensor(s) that shall use channels 3 and 4 via the sensor menus.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
CAUTION!
Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module!
This will avoid static discharges that can damage the module or the box.
