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 of upgrades.
A forklift should be used to remove the FCS cabinet from its shipping crate. Once on a level
floor, the cabinet can be pushed in place using it’s own casters. Levelers at each corner may be
used to prevent the unit from moving. Levelers are not intended to support the entire weight of
the cabinet howewer.

The FCS II Series AC power sources can be used free standing on a solid surface. The units
are fan cooled, drawing air in from the front and exhausting at the rear. The back of each unit
must be kept clear of obstruction and a 6” clearance must be maintained to the rear. Spec

considered at all times to avoid self heating and over temperature problems.
Multi chassis configurations such as the FCS36/2 or FSC54/3 consist of two or three self-
contained FCS18 power sources. They must be connected through the system interface using
the supplied DB25 to DB25 cable. Output wiring from each chassis to th
wire gage and length to ensure proper current sharing between units.
Note that for multi-chassis systems, it is recommended to turn the Master unit ON first and th
