Installation
The EC4E-card must only be installed and wired up by
qualified electricians or other persons familiar with the
installation of electrical equipment.
The EC4E module is installed in the following order:
• Mounting,
• Wiring up the inputs,
• Wiring up the outputs,
• CAN-connect/separate to/from network
• Connecting the power supply.
Mounting
Install the EC4E module in a control panel, distribution board
or other enclosure so that the power feed and terminal
connections cannot accidentally come into contact during
operation.
Snap-fit the EC4E module onto a DIN EN 50022 mounting
rail or secure it with fastening brackets. You can fit the EC4E
module vertically or horizontally.

If you are using the EC4E module with
an
expansion unit,
