6. Exercise extreme caution when cables are over four feet in length.
7. Turns off AC power (or disable unit) before disconnecting load or floating voltages.
8. Operates the power supply with properly rated wire sizes.
1.5 LOCATION AND COOLING
1. The proper operating temperature for the power supply are from 0°C to 50°C. The unit ventilates by drawing
air through the sides and exhausting it through the rear.
2. Proper ventilation area for the power supplies is at least 1" of spacing on all sides.
3. The PPSs are built to configure into 1/2 rack mount configurations.
1.6 GPIB INTERFACE CONNECTOR
The GPIB connector on the rear panel connects your supply to the computer and other GPIB devices. A GPIB
system can be connected in any configuration (star, linear, or both) as long as the following rules are observed:
1) The total number of devices including the computer should not be greater than 15.
2) The total length of all cables used should not be more than 2 meters times the number of devices connected
together, or a maximum length of 20 meters.
Please do not stack more than three connector blocks together on any GPIB port. The resulting leverage can exert
excessive force on the mounting panels. Make sure that all connectors are fully seated and that the lock screws are
firmly
hand tightened
. Use a screwdriver only when removing the screw from the mounting panels.
