Page 22: Connect The Ac Mains
Assembly Connect the AC Mains SHOCK HAZARD. Make sure that the AC mains cables are NOT WARNING connected to the AC mains. Only connect the AC mains cables to the AC mains as the final step in the installation procedure. Install the AC mains cables into the cabinet first - before you install the power supplies or make any other connections. -
Page 23: Install The Power Supplies
Assembly Install the Power Supplies Use caution when installing power supplies. Power supplies weigh as much as 78 lbs. (35.5 kg). Two people are CAUTION required when installing power supplies. Because of the unit’s weight, do not lift or move it alone. Moving by hand should be avoided where possible. -
Page 24: Install The Bus Bars
Assembly Install the Bus Bars Remove the bus bars from their storage locations High current bus bars weigh up to 28 lbs. (13 kg) each. Use caution CAUTION when lifting and moving the bus bars. Lay them down so that they do not fall. - Page 25 Assembly Because of the difference in thickness of the high-current bus bars, use the longer (40 mm) screws to connect the bottom three units. Use the shorter (30 mm) screws to connect the top three units. Once the single screws are installed, install the remaining two screws on each rear terminal.
- Page 26 Assembly 4. Once all connection screws are installed as shown in the following fugures, tighten the screws according to the following torque settings. • For the high-current bus bars, maximum torque is 9.2 lb-ft (12.4 Nm). • For the high-voltage bus bars, maximum torque is 5.4 lb-ft (7.3 Nm).

Page 35: Turn-On Checkout
Operation Turn-On Checkout Turn the Rack On HAZARDOUS VOLTAGES All power supplies generate voltages in excess WARNING of 60 VDC, with some models rated at up to 1,500 VDC! Ensure that all output connections are either insulated or covered so that no accidental contact with lethal output voltages can occur. - Page 36 Operation 4. Enable the Output. Push the On/Off key to enable the output. If a load is connected to the output, the front-panel display will indicate that it is drawing current. Otherwise, the current reading will be zero. The status indicator shows the output’s status. For example, "CV"...
