Installation and Setup Guide 2 Rack Mounting the Array • Mount the array in a horizontal orientation, or you will void your array warranty and support contract. Environmental Requirements The rack location must meet the following environmental requirements: • The power source can supply a voltage range of 100V to 240V AC. • The power source has sufficient electrical overload protection: In North America, connect the array to a source of power with over-current protection provided by a double pole 20A or less device (UL 489 circuit breakers). In Europe, the over-current protection must be provided by a 20A or less device (IEC circuit breakers). • There is sufficient space for air flow in front of and behind the array. • The location is properly vented. • Your environment supports all of the requirements listed in the Power Supplies on page 29. Protecting Hardware Protect your PS Series array from electrostatic discharge. When handling array hardware, use an electrostatic wrist strap or a similar form of protection. To use a wrist strap: 1. Connect the steel snap on the coil cord to the stud on the elastic band. See Figure 1. Figure 1: Using an Electrostatic Wrist Strap 2. Fit the band tightly around your wrist. 3. Connect the band to ground. You can either plug the banana connector into a matching grounded receptacle, or attach it to the matching alligator clip and connect the clip to a grounded device. Examples of an appropriate ground would be an ESD mat, or the metal frame of a grounded piece of equipment. Shipping Box Contents and Required Hardware Make sure you have all the items supplied in the shipping box, described in Table 1. You must provide additional hardware that is specific to your environment and not included in the shipping box. See Table 2. 4

orientation,
or
you
will
void
your
array
warranty
and
support
contract.
Environmental
Requirements
The
rack
location
must
meet
the
following
environmental
requirements:
•
The
power
source
can
supply
a
voltage
range
of
100V
to
240V
AC.
•
The
power
source
has
sufficient
electrical
overload
protection:
In
North
America,
connect
the
array
to
a
source
of
power
with
over-current
protection
provided
by
a
double
pole
20A
or
less
device
(UL
489
circuit
breakers).
In
Europe,
the
over-current
protection
must
be
provided
by
a
20A
or
less
device
(IEC
circuit
breakers).
•
There
is
sufficient
space
for
air
flow
in
front
of
and
behind
the
array.
•
The
location
is
properly
vented.
•
Your
environment
supports
all
of
the
requirements
listed
in
the
Power
Supplies
on

Protecting
Hardware
Protect
your
PS
Series
array
from
electrostatic
discharge.
When
handling
array
hardware,
use
an
electrostatic
wrist
strap
or
a
similar
form
of
protection.
To
use
a
wrist
strap:
1.
Connect
the
steel
snap
on
the
coil
cord
to
the
stud
on
the
elastic
band.
See
Figure
1
.
Figure
1:
Using
an
Electrostatic
Wrist
Strap
2.
Fit
the
band
tightly
around
your
wrist.
3.
Connect
the
band
to
ground.
You
can
either
plug
the
banana
connector
into
a
matching
grounded
receptacle,
or
attach
it
to
the
matching
alligator
clip
and
connect
the
clip
to
a
grounded
device.
Examples
of
an
appropriate
ground
would
be
an
ESD
mat,
or
the
metal
frame
of
a
grounded
piece
of
equipment.
