Introduction

NRD317880 Issue A

1Introduction

1.1 Scope and definitions

The Acoustic Enclosure is designed to be used in an industrial or laboratory environment. All Edwards XDS and nXDS
scroll pumps will fit the nXDS/XDS Acoustic Enclosure and all RV and EM pumps up to E2M28 will fit the RV/EM Acoustic
Enclosure.

The enclosure is designed to slot together without removable fixings and so requires no tooling to assemble or
dismantle it. It is powered by a power cable fitting into an IEC 320 socket.

Note: The power cable for the pump is connected to its own supply. This supply should have an external means of

isolation and not rely upon the on/off switch located on the pump.

Read this manual before installing and operating the Acoustic Enclosure. Important safety information is highlighted
as WARNING and CAUTION instructions; these instructions must be obeyed. The use of WARNINGS and CAUTIONS is
defined below.

CAUTION

Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.

The following warning labels appear on the Acoustic Enclosure:

WARNING

Warnings are given where failure to observe the instruction could result in injury or death to
people.

Warning - refer to accompanying documentation.

Warning - risk of electric shock.
