Any disassembling of the case or changing the fuse not performed by an
authorized service technician will void the warranty of the instrument
SHOCK HAZARD:
Hazardous voltages may exist at the outputs and the load connections when using a power
supply with a rated output greater than 60 V. To protect personnel against accidental contact with
hazardous voltages, ensure that the load and its connections have no accessible live parts. Ensure that
the load wiring insulation rating is greater than to the maximum output voltage of the power supply.
The rear output terminals can accept wire sizes AWG 24 to AWG 12 (See Table 2.1).However, we recommend using 12
AWG if current output is between 5 to 10 A. Refer to Table 2 below to determine the proper wire size.

Output Isolation
The output terminals of the 9240 Series are isolated from earth ground. An earth ground terminal is provided on the
front panel for convenience. Any output terminal may be grounded. However, output terminals must not exceed ±200
VDC.
SHOCK HAZARD
Floating voltage must not exceed 200 VDC.
