Instruction Manual for CXS Control Box
Components must not be added to the control box. Some of the entries are for connection to the CXS pump, display
module or ancillaries (e.g. boosters) and must be closed with suitable fittings, i.e. either suitable rated stopping
plugs or cable and cable glands, as detailed below in Table 4.
The only entries allowed for connection to the user's equipment/services are marked with a # and must be closed
with suitable fittings as detailed below in Table 5.

Materials of construction
2.2 Cooling water data
Cooling water is required to cool the CXS pump system, including elements within the CXS control box. Refer to
Table 2 for the minimum requirement based on the control box certification.
Note: If the pump is operated at lower temperatures higher flow rates may be required for reliable operation.
Table 2 - Cooling water data
3 Materials of construction
Table 3 - Materials of construction
4 Instructions for use
In order to operate the CXS system the mains power supply must be connected to the control box.
The mains power connector and the interface connections must be made using the combination of tested cable glands
and cables listed in Table 4 or by using alternative cables (suitably electrically rated) along with certified Exd
compound glands.
Table 4 - Cable and cable glands for customer connection
Please refer to Figures 3, 4and 5for the type and size of thread.
The installation may only be performed by qualified personnel, which have been suitably trained for this purpose.
All suitable national regulations of the country of use have to be followed.
Any unused entry threads should be sealed with an appropriate Exd rated blanking plug.
4.1 Opening the control box
When opening the control box either by taking off the front lid or one of the cable gland plates or cover plates, you
must ensure that the flame-path surfaces are kept clean and scratch-free. Please refer to Figures 6to 10.
Minimum water supply 4 l/min

Figure 10 - Terminal cover flame path
1. Unscrew the fasteners on the lid and/or cover/gland plates.
2. Open and remove the lid or plates carefully (the lid is hinged - it is advised not to remove it completely unless
necessary).
3. Store the lid and/or plates in a way to ensure that no damage will be made to the flame-path surfaces.
4. When fitting the lid and/or plates take special care that the flame-paths are not damaged.
5. Tighten the fasteners using the specified tightening torque.
6. Check the gaps between the gland plates and control box and lid and control box to the specification given in
Figure 4.
You must use the fasteners provided with the box or source replacements to the specification below. After
unscrewing the fasteners, keep them in a safe place and ensure they are clean and undamaged if re-using them.
Specification for replacement fasteners:
M8x1.25 6g 12.9 ENP ISO4762
The following table lists the cable/gland combinations that have been tested and approved, for use with the
connections to the CXS system and ancillaries (eg booster pump), in addition to the mains and interface combinations
listed in Section 4.1. These connections will be made by Edwards during the manufacture of the CXS system.
Connections must be made using the following combination of tested cable glands and cables or by using alternative
cables (suitably electrically rated) along with certified Exd compound glands.
WARNING
Any scratches or damage on the flame-path surfaces (refer to Figures 6to 10) will impair the
explosion protection of the CXS Exd control box. Handle all enclosure covers with care. If any
flame-path surface is damaged you must replace that part before re-using the enclosure.

* Temperatures at the entry point for the motor cable can be as high as 77°C under rated conditions. If
another cable than the ones listed in Table 5 are chosen, this higher temperature rating has to be taken into
account.

WARNING
Entries must be fitted with the gland/cable combinations detailed in this manual, or by using
alternative cables (suitably electrically rated) along with certified Exd compound glands,
otherwise the explosion protection can no longer be guaranteed.
All unused entries in the enclosure must be closed using certified Exd blanking/stopping plugs to
guarantee the explosion protection of the control box. If any entries are left open the explosion
protection of the control box can no longer be guaranteed. Refer to Figure 4 for information on
thread type on all entries.

Return the equipment or components for service
Before you send your equipment to us for service or for any other reason, you must send us a
completed Declaration of Contamination of Vacuum Equipment and Components – Form HS2. The
HS2 form tells us if any substances found in the equipment are hazardous, which is important for
the safety of our employees and all other people involved in the service of your equipment. The
hazard information also lets us select the correct procedures to service your equipment.
We provide instructions for completing the form in the Declaration of Contamination of Vacuum
equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
 If a pump is configured to suit the application, make a record of the configuration before
returning the pump. All replacement pumps will be supplied with default factory settings.
 Do not return a pump with accessories fitted. Remove all accessories and retain them for
future use.
 The instruction in the returns procedure to drain all fluids does not apply to the lubricant in
pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/, follow the procedure in
HS1, fill in the electronic HS2 form, print it, sign it, and return the signed copy to Edwards.
Note: If we do not receive a completed HS2 form, we will not accept the return of the
equipment.
