Grounding the Terminal Housing
To ensure that the Inverter is properly grounded and protected, an earthing cable MUST be
fitted to the Terminal Housing of the G110M system.
● Connect the PE terminal on the left-hand side of the inverter 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
Introduction
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).
At the base of the 24 V PSU housing is a cable gland opening (which is sealed with a
blanking plug) which provides and entry point for the cables from an external braking
resistor.
