3. Unpacking and Installation
3.1 Unpacking
Inspect the unit for any possible shipping damage immediately upon receipt. If damage is evident,
notify the carrier. DO NOT return an instrument to the factory without prior approval. Do not destroy
the packing container until the unit has been inspected for damage in shipment. If possible, retain the
container in the event the system ever has to be returned to the factory for either repair or upgrades
WARNING: This power source weighs approximately 60 lbs / 28 Kg. Obtain adequate help
when moving or installing the unit. For cabinet mounting, use rack supports to support the
weight.
3.2 AC Input Power Requirements
The i/iX Series power source has been designed to operate from a single-phase, two wire AC input
line. A protective earth connection is required as well. (PE). Available AC input setting is either 115
or 230 VLN nominal.
CAUTION: Always check the input rating on the AC input voltage selector switch located
on the rear panel before connecting AC input power.
3.3 Mechanical Installation
3.3.1 Table top
The iX Series AC power sources can be used free standing on a solid surface or mounted in a 19”
instrument cabinet. The units are fan cooled, drawing air in from the side and exhausting at the rear.
The back of each unit must be kept clear of obstruction and a 3” clearance must be maintained to the
rear. Special consideration of overall airflow characteristics and the resultant inte
rnal heat rise must
d at all times to avoid self heating and over temperature problems.
3.3.2 Rackmount
be considere
If the power source is to be mounted in cabinet system, proper supports such as L-brackets or a she
must be provided to support the weight of the unit along its depth. The rack ears on the front of the
power source are not intended to supp
lf
ort the entire weight of the unit and should only be used to
Suitable L-brackets for 26”
are available from California Instruments. (-RMK option)
3.3.3 Multi chassis
prevent the unit from sliding forward.
Contact the cabinet manufacturer for suitable rack support accessories.
deep cabinets
Multi chassis configurations consist of two self-contained iX Series power sources. They must be
connected through the system interface using the supplied cable. Output wiring from each chassis to
the EUT must be of equal wire gage and length to ensure proper current sharing between units.

3.4 Rear Panel Connectors
All connections to and from the power source are made at the rear panel. For the location of the
connectors and types used, refer to Figure 3-1 for i Series models or Figure 3-2 for iX Series models.

3.5 AC Input Wiring - INPUT
AC input connections are to be made directly to the input terminal block. The AC input terminal block
is located on the right hand side on the back of the chassis (when facing the back of the unit). It is
labeled “AC INPUT”.
Before connecting the input wiring, the AC input safety cover (P/N 6005-214-1) stand-offs must be
installed. The two stand-offs and screws required to mount the safety cover are provided in the ship kit
(envelope) that comes with the AC power source. Screw the stand offs on to the AC input terminal
strip mounting screws (top and bottom of terminal block. Attach the safety cover to the stand offs
using the provided screws after connecting the AC input wiring. Refer to Figure 3-3.
Figure 3-3: AC Input safety cover installation – Viewed from top.
Ground (earth) wire must be connected to the chassis of the AC power system using the ground
connection of the AC input terminal block. The mains source must have a current rating equal to or
greater than the input fuses and the input wiring must be sized to satisfy the applicable electrical
codes.
The AC input terminal strip accommodates a #6 ring or spade lug. The use of sleeved ring lugs
