POWER
Power connection should be made to the three terminal connector as shown in figure 3. Also, make note that it is very
important that the power line inputs and the power ground are not switched. Doing so will permanently damage the
instrument. Refer to Figure 3 for proper connections. For convenience, the printed circuit board is labeled
L1 L2 GND on the under side of three terminal power connector. For instruments with the 15Vdc power option, refer
to Figure 3.
NOTE: WHILE CONNECTING POWER TO THE UNIT, MAKE SURE THAT AC POWER LINE L1 OR
L2 IS NOT ACCIDENTALLY CONNECTED TO GROUND (GND) TERMINAL. THIS WILL RESULT IN
PERMANENT DAMAGE TO THE INSTRUMENT.
DOUBLE CHECK THE CONNECTIONS BEFORE APPLYING POWER!!
