9.4.5 Installation and Acceptance
9.4.5.1 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.
9.4.5.2 Power Requirements
The EOS-1 and EOS-3 electronic switches use either 115 or 230 VAC to power the control
circuits. The user may select the desired input voltage using the range selector within the input
module.
To change the input voltage range, pry open the cover to the input module. Remove the fuse
carrier. Install the correct fuses in the carrier. Reinstall the carrier into the input module so that
the desired voltage range appears in the module cover window. Close the cover.
Note that attempting to operate the EOS from an input range that does not match the actual AC
power voltage may cause permanent damage to the unit.
The line power source to the EOS must provide protective earth grounding.
9.4.5.3 Mechanical Installation
The EOS-1 and EOS-3 have been designed for rack mounting in a standard 19 inch rack. The
unit should be supported from the bottom with a shelf-track or supported from the sides with
optional rack slides (-RMS option).
The cooling fan at the rear of the unit must be free of any obstructions that would interfere with
the flow of air. A 2.5-inch clearance should be maintained between the rear panel of the EOS
unit and the rear panel of the mounting cabinet. Also, the air intake holes on the sides of the
power chassis must not be obstructed.
