Fluke 5320A-LOAD Instruction Sheet

Introduction

The 5320A-LOAD High Voltage Load Adapter
(hereafter the Load) is designed for loading a
hipot tester to create leakage current while
performing hipot tester calibration with the 5320A
Electrical Safety Tester Calibrator (hereafter the
Calibrator). As shown in Figure 1, this Load
consists of a series of eight power-rated resistors
configured to provide eight resistance taps from
10 kΩ to 5 MΩ. The Load is designed to
withstand a maximum voltage of 1.2 kV to
5.5 kV, depending upon the selected resistor.

XWWarning
To avoid possible electric shock or
personal injury, use this Load only as
specified in this Instruction Sheet or
the 5320A Calibrator Users Manual.

Preparing for Operation

The Load is shipped with a power line adapter
(to run the cooling fans), a grounding cable, and
this Instruction Sheet.
The power line adapter comes with five different
mains plug adapters for compatibility with
different power plug configurations. Prior to use,
select the appropriate plug adapter which
matches the local power mains outlet. After

attaching the plug to the power line adapter it is
ready for use with the Load.
After placing the Load on top of the Calibrator,
connect the grounding cable between the Load's
rear-panel ground terminal and the Calibrator's
rear-panel ground terminal.
XW Warning
To avoid electric shock from high-
voltage energy, ensure the ground
terminal on the rear of the Load is
connected to the ground (GND)
terminal on the rear of the Calibrator.
Any application with non-grounded
housing is strictly prohibited.
W Caution
To prevent damage to the Load,
ensure the vents on the bottom of the
Load and the fan exhaust vents are
clear of obstructions for proper
cooling.
Connect one end of the power line adapter to the
mating power input connector socket on the rear
panel of the Load and the other end into the
mains power outlet.
WCaution
Failure to have the fans operating
may lead to over heating and
component failure.
