General Safety Summary
Please review the following safety precautions carefully to avoid
personal injury or damage to this product or any product connected
to it. To prevent potential danger, please use the instrument as
specified.
Use proper power cord
Only the power cord designed for the instrument and authorized by
local country could be used.
Power supply
AC Input Voltages: 100V/110V/220V/230V ±10%, 50/60Hz.
Use proper fuse
The fuse types: 100V/110V(T6.3A/250V) 220V/230V
(T3.15A/250V)
Make sure to use the correct type of fuse before turning on the
instrument.
Do not connect the power cord before replacing the fuse.
Find out the reason why the fuse burned out before replacing the
fuse.
Ground the instrument
The instrument is grounded through the protective terra conductor
of the power cord. To avoid electric shock, the grounding conductor
must be connected to the earth. Make sure that the instrument is
properly grounded before any inputs or outputs.
Observe all terminal ratings
To avoid fire or electric shock, please observe all ratings and
symbols on the instrument. Read this guide carefully to know more
details about the ratings before connection.

Chapter 1 Quick Guide
In this chapter, we mainly introduce the panel display interface
and inspecting the new machine.Reading the following steps will
give you a quick understanding on operation.
General Inspection
1. Inspect the shipping container.
Keep
the damaged shipping container or cushioning material
until the contents of the shipment have been completely
checked and the instrument has passed both electrical and
mechanical tests.
2. Inspect the instrument.
If
there are instruments found damaged, defective or failure in
electrical and mechanical tests, please contact us.
3. Check the accessories.
Please check the accessories according to the packing list. If the
accessories are incomplete or damaged, please contact us
.

Safety Considerations
To ensure that the instrument can work normally, please conduct
necessary inspection before using the RSPD3303C.
Input Power Requirement
The RSPD3303C allows a 50Hz/60Hz frequency, and four levels of
AC power: 100V/120V/220V/230V. You can select required power
voltage with the “DIP Switch ” at the rear panel according to the
actual demand.
Warning
To switch to the required power voltage, please disconnect the
power cord first.
Electrical Check
Please use the power cord provided and connect the
instrument to AC power. Check the power as follows.
1. Connect the power supply
Warning
To avoid electric shock, please make sure that the instrument is
grounded correctly.
2. Turn on the power switch
Press the button POWER to enter boot interface, the system
then returns to the default setting.
