Grounding the terminal housing
Description
To ensure that the converter is properly grounded and protected, an earthing cable must be
fitted to the Terminal Housing of the converter.
• Connect the PE terminal on the left-hand side of the converter to appropriate grounding
point of the installation.
• Use a short wire connection.
• Clean the connection to the steel construction from paint or dirt.
• Use a ring clamp to terminate the cable to ensure a good physical connection which is
resistant to accidental disconnection.

Installing the 24V power supply
Overview
The optional 24 V PSU allows the user to draw the necessary 24 V to power the internal
electronics of the Control Module direct from the converters DC link voltage. This has the
advantage that no external cabling is required and therefore, only a 3-phase mains supply cable
is required.
The following electronics are powered by the optional 24 V PSU:
• Internal circuits in the Control Module (CM).
• Low voltage components in the Power Module (PM).
• All input and output, for example the digital outputs on the Communications and Power
Interface (CPI).
