1.6 SAFETY PRECAUTIONS
All 203 and 303 power supplies are designed to mini-
mize the risk of fire or shock hazard. This instrument
received comprehensive mechanical and electrical in-
spection prior to shipment. Nevertheless, certain safety
precautions must be observed. Only TECHNICALLY
QUALIFIED SERVICE PERSONNEL familiar with the principles of electrical safety should
operate this supply. The power supply SHOULD NOT BE EXPOSED TO WATER
(EXCEPT COOLING CONNECTIONS) OR MOISTURE OR DUSTY ENVIRONMENTS.
Electrical safety must be maintained at all times.
Lethal voltages are developed within the power supply's enclosure and at the output ca-
ble. Therefore, the cover may not be removed by the user (see Warranty in preamble sec-
tion for variance). Also, the large capacitors in the supply may store power even after the
AC input line is removed. ALLOW AT LEAST 40 SECONDS DISCHARGE TIME between
removing the AC input line and opening the cover. ALSO, ALLOW AT LEAST 40
SECONDS between switching the AC power off and switching it on again.
1. This product is designed for Indoor use
2. This product is designed for pollution degree 2.
3. This product is designed for Transient Overvoltage Category II
4. Ensure all covers are in place and securely fastened before switching ON the AC power.
5. Proper grounding from the input AC power is required to reduce the risk of electric
shock. Ensure that the AC Protective Earth Ground connection has at least the same
gauge wire as the supply leads shown in Table 4-1.
6. Where high leakage exists and there is a warning label on the rear panel, the Protective
Earth Ground must be connected. (Symbol for protective earth ground ).
7. Use extreme caution when connecting AC input power, and never apply the incorrect in-
put voltage, refer to ratings label.
8. Use extreme caution when connecting the high voltage output cable to the load.
9. Ensure all load capacitors are completely discharged prior to connection. Never handle
the output cable when the power supply is operating.
