Load Connections
WARNING
DO NOT EXCEED LOAD INPUT VOLTAGE RATING
This instrument does NOT have a means to disconnect its Load input from a
connected power supply. If the voltage applied to the Load input exceeds its
maximum rating – even if the load is turned completely off – damage to the load
WILL occur. Damage caused by exceeded maximum load input voltage under any
circumstance is NOT covered by the manufacturer’s product warranty. Remove any
load input connections when the load is not in use, even when it is turned off.
When setting up for a new test and connecting any equipment to the DC load, proceed as
follows:
1.
Always make sure the DC load is turned OFF at the POWER switch when making any
wire connections.
2.
Check that the output of the equipment under test is
OFF
.
Note:
Some power equipment’s output may still be energized even if the equipment
has been turned off or its output is turned off. This is especially true for DC power
supplies.
Note:
When working with batteries, it is recommended to provide a suitable
disconnect relay or switch so the load connection can be disconnected from the
battery for handling purposes.
3.
Connect one end of the load wires to the load input terminals on the rear panel.
4.
Check the polarity of the connections and connect the other end of the load wires to
the output terminal of the equipment under test.
5.
When connecting multiple loads to the same EUT, makes sure the load wire lengths
to each load are the same.
