Connect The Epx Pump To The Electrical Supply - Edwards EPX HiVac Series Instruction Manual

3.10

Connect the EPX pump to the electrical supply

Connect the electrical supply to the EPX pump through a suitable fuse/ isolator rated as specified
in Section 2.3.
Do not operate the EPX pump unless it is correctly earthed (grounded) using the protective earth
stud (Figure
Ensure that the electrical supply and connectors are rated for the voltage of the pump as marked
on the rating label attached to the mains inlet cover.
There are no user serviceable parts within the EPX pump. Metal covers must not be removed from
the pump; to do so may cause damage to the pump and injury to personnel and would invalidate
the declaration of conformity and the warranty. Qualified Edwards service personnel should allow
4 minutes after the isolation of power before removing any covers.
Use the following procedure to connect the EPX pump to the electrical supply:
1. Use a suitable earth (ground) cable to connect the M8 protective earth (ground) stud
EPX pump to a suitable earth (ground) point: refer to
2. If an electrical supply plug is not fitted:
Connect the four core electrical supply cable to earth (green/yellow) and three phases (1, 2, 3 respectively)
by direct connection to a suitable control box with a means of isolation, and by means of a suitably IP rated
four pin connector.
Notes: 1. If you connect the electrical supply to the EPX pump through ELCB relays, they must be suitable for the
protection of equipment with a d.c. component in the fault current, and suitable for short-duration
switch-on surges, and for high leakage currents (for example, type B, according to prEN50178).
2. If you have a plug to connect the EPX pump to your mains disconnect device, you must provide Lockout/
Tagout in conformance with the requirements of SEMI S2-0200 Section 17.
The mains disconnect device should conform with all the following statements:
The mains disconnect device must be provided by the user and should be in a location satisfying the
requirements of SEMI S8 where it is readily accessible.
The mains disconnect device should not be located where there is any risk of personnel tripping on cables,
being obstructed or exposed to other hazards.
The mains disconnect device should be marked as a disconnection device.
The mains disconnect device must be connected between the source of supply and the main power cable
entering the EPX pump.
The mains disconnect device must have a lockout/tagout facility of the type specified in Section 17 of SEMI
S2-0200.
The mains disconnect device must be rated at a minimum of 10,000 AIC.
