1. Safety and compliance
1.1 Denion of Warnings and Cauons
NOTICE:
For safe operaon from the start, read these instrucons carefully before you install
or commission the equipment.
Read all the safety instrucons in this secon and the rest of this manual carefully
and make sure that you obey these instrucons. The equipment must only be
operated and maintained by trained personnel in the proper condion and as
described in this instrucon manual.
Obey local and state requirements and regulaons. If you have any quesons about
safety, operaon or maintenance of the device, please contact our nearest subsidiary.
Important safety informaon is highlighted as warning and cauon instrucons. Obey
these instrucons.
WARNING:
If you do not obey a warning, there is a risk of injury or death. Dierent symbols are
used according to the type of hazard.
CAUTION:
If you do not obey a cauon, there is a risk of minor injury, damage to equipment,
related equipment or process.
NOTICE:
Informaon about properes or instrucons for an acon which, if ignored, will
cause damage to the pump or the system.
We reserve the right to change the design and the stated data. The illustraons are not
binding.
Keep the instrucons for future use.

2. Important safety informaon
WARNING: ELECTRIC SHOCK
Failure to obey the informaon that follows this Warning could result in injury or
death by electric shock. Read and obey this safety informaon.
▪The electrical installaon must be done by a suciently qualied person. Obey
the naonal regulaons in the country of use (for example, EN 50110-1 for
Europe).
▪Lethal voltages are present at the mains connecons. Before you start
maintenance and service work, de-energise (lockout/tagout) the product rst.
▪Unplug any connectors only when the mains voltage is switched o and the pump
does no longer turn.
▪At speeds below 200 Hz, there is not enough power for the LEDs. The pump can
connue to operate without LED indicaon.
▪Unauthorized device conversion and modicaons are prohibited for safety
reasons.
▪Hazardous voltages are present within the converter. Contact with the converter
can cause death or injury. Aer the pump has stopped, disconnect the converter
from the mains power. Make sure that the pump cannot be accidentally switched
on (lockout/tagout) before you open it. There are no user serviceable parts in the
converter.
▪Put connecng lines so that they cannot be damaged. Protect the lines against
humidity and contact with water. Prevent any heat stress on the line due to
unfavourable condions.
▪ Support the connecng lines so that the pumps are not exposed to major
mechanical stress.
▪ Do not expose the converter and the connecons to dripping water. Read the
informaon on the IP type of protecon.
▪ When converter and connecng lines are stored in a humid atmosphere, they can
suer corrosion. Corrosion can cause conducve deposits which can cause short-
circuits and reduce the insulaon levels of electrical components
▪Transport the converter and connecng cables in their original packaging to avoid
mechanical damage. This can prevent air gaps and creepage distances.
▪Do not make electrical connecons unl the pump and accessories (e.g. air
cooler) have been installed mechanically.

4. Installaon
4.1 Placement
Put the EPS 500 on a at, smooth surface or aach it with screws. If the EPS 500 is not
aached with screws, install the supplied rubber feet.
CAUTION
Do not block the heat dissipaon of the EPS 500. Make sure there is sucient
venlaon. The ambient temperature during operaon must not exceed 40 °C (104
°F).
WARNING
If the EPS 500 is built into a device, install a safety switch cut-o between the EPS 500
and the mains.
CAUTION
Do not operate the EPS 500 with the tested mains cable in a chemically aggressive
environment. If you operate the EPS 500 in a chemically aggressive environment
replace the mains cable with a resistant one.

5. Maintenance
Dust and moisture can cause contaminaon in the power supply. This contaminaon can
cause the power supply to overheat or short-circuit. We recommend that the power
supply is cleaned every 5 years.
5.1 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 Declaraon of Contaminaon 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 informaon also lets us select the
correct procedures to service your equipment.
We provide instrucons for compleng the form in the Declaraon of Contaminaon of
Vacuum equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
▪ If a pump is congured to suit the applicaon, make a record of the conguraon
before returning the pump. All replacement pumps will be supplied with default
factory sengs.
▪ Do not return a pump with accessories ed. Remove all accessories and retain
them for future use.
▪ The instrucon in the returns procedure to drain all uids does not apply to the
lubricant in pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/, follow the
procedure in HS1, ll in the electronic HS2 form, print it, sign it, and return the signed
copy to us.
NOTICE:
If we do not receive a completed HS2 form, your equipment cannot be serviced.
