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.

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).
