1.1 Introduction
This document covers DC bus paralleling instructions for Unidrive M600/
M70X, F300, H300, E200 & E300 size 6 drives. The Unidrive M terminal
and enclosure design enables the DC bus of a number of drives to be
connected together using a pre-formed busbar kit.
Table 1-1 DC bus paralleling kits
The following instructions describe the DC bus paralleling of two
Unidrive M size 6 drives. Throughout this sheet, the drives are labelled 1

Stored charge
The drive contains capacitors that remain charged to a
potentially lethal voltage after the AC supply has been
disconnected. If the drive has been energized, the AC supply
must be isolated for at least ten minutes before work may
continue. Refer to section 3.1 Safety information in the
User
Guide.
Isolation device
The AC / DC supply must be disconnected from the drive
using an approved isolation device before any cover is
removed from the drive or before any servicing work is
performed.
Follow the instructions
The mechanical and electrical installation instructions must
be adhered to. Any questions should be referred to the
supplier of the equipment. It is the responsibility of the owner
or user to ensure that the installation of the drive and any
external option unit, and the way in which they are operated
and maintained, comply with the requirements of the Health
and Safety at Work Act in the United Kingdom or applicable
legislation and regulations and codes of practice in the
country in which the equipment is used.
