Note The power supply is shipped from the factory with a power-line cord that has a plug
appropriate for your location. Your power supply is equipped with a 3-wire grounding
type power cord; the third conductor being the ground. The power supply is grounded
only when the power-line cord is plugged into an appropriate receptacle. Do not
operate your power supply without adequate cabinet ground connection.

Warning Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator. Do not float the outputs more than ±60 Vdc
when uninsulated sense wires are used to connect the (+) output to the (+) sense and
the (-) output to the (-) sense terminals on the back of the unit.

Current Ratings
Table 2-1 Wire Rating
Warning To satisfy safety requirements, load wires must be heavy enough not to overheat when
carrying the maximum short-circuit output current of the power supply. If there is
more than one load, then any pair of load wires must be capable of safety carrying
the full-rated current of the power supply.

Note The power supply’s OVP circuit contains a crowbar SCR, which effectively shorts the
output of the power supply whenever the overvoltage condition occurs. If external
voltage source such as a battery is connected across the output, and the overvoltage
condition inadvertently occurs, the SCR will continuously sink a large current from
the source; possibly damaging the power supply. To avoid this a diode must be
connected in series with the output as shown in Figure 3-1.

Caution If you send two query commands without reading the response from the first, and then
attempt to read the second response, you may receive some data from the first response
followed by the complete second response. To avoid this, do not send a query
command without reading the response. When you cannot avoid this situation, send
a device clear before sending the second query command.
