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.

2.1 Specifications
Figure 1 - Specifications of nXDS/XDS and RV/EM pumps
The fuse rating is 5 amps, Type T, 20mm long x 5mm diameter (RS668-6010 or equivalent).
The Acoustic Enclosure can be used to attenuate the noise from the XDS, nXDS range of scroll pumps, EM and RV
pumps typically by the figures listed in Table 1.
Two fans are fitted. Fan 1 starts up when the power is on. Fan 2 is controlled by a thermal switch set to operate when
the internal temperature exceeds 35 ± 5°C.

3 Installation
3.1 Safety
A suitably trained and supervised technician must install the Acoustic Enclosure.
Ensure that all equipment is safe and in a suitable condition to be installed in the enclosure.
For safety issues, refer to Edwards Vacuum Pump and Vacuum System Safety Publication P400-40-100 or
contact Edwards if in doubt.
Casters should be locked when the pump is in operation.
Route all electrical cables in a safe manner.
WARNING
Obey the safety instructions given below and take note of appropriate precautions. Failure to do
so can cause injury to people and damage to equipment.
WARNING
Care should be taken when removing the enclosure from the packaging and also when removing
the enclosure side panels.
WARNING
Use suitable lifting equipment or at least two people to lift the empty Acoustic Enclosure.
WARNING
Do not lift the Acoustic Enclosure with a pump installed.
WARNING
Be careful not to drop any of the enclosure panels during assembly/disassembly as this may either
damage the panel or cause injury.
WARNING
Do not install the enclosure on a slope. When the casters are unlocked the enclosure could move
and cause injury.

After removing all packaging:
Remove side panels by lifting (this will disengage the panel from the locating pins) and moving to the side. Be
careful not to drop a panel.
Insert nXDS/XDS pump - refer to Figure 2.
Attach inlet and exhaust fittings. Note that sufficient length will be needed to clear enclosure.
Locate first panel on left hand side of pump - refer to Figure 3.
Adjust pump position to suit.
Position pump power cable through hole provided.
Switch the pump start switch to ON.
Fit second cover to right hand side of pump - refer to Figure 4.
3.3 Installing RV EM Acoustic Enclosure
The various elements of the Enclosure are designed to slot together without additional fixings.
