Connect the
EPX
pump to the electrical supply
WARNING
Ensure
that the
electrical installation of the pumping system conforms
with
local,
regional,
and
national
electrical codes and
safety
requirements.
It
must be
connected to
an appropriately
protected electrical supply and earth (ground) point.
WARNING
Connect
the
electrical supply
to
the EPX pump
through
a
suitable
fuse/
isolator
rated as specified
in
Section
2.
3.
WARNING
Do not
operate
the EPX pump unless it
is correctly
earthed
(grounded)
using
the
protective earth
stud
(Figure
2, item
3).
WARNING
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.
WARNING
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
(Figure
2,
item
3)
on the
EPX
pump to
a
suitable
earth
(ground)
point: refer to
Section 2.3
for
the cable
rating.
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 connecting the
electrical
supply
to
the
EPX
pump through
ELCB
relays,
it 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
8,
according
to prEN50178).
2. If using a plug
to connect
the
EPX
pump to
the
mains disconnect
device,
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 58 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.
