2.4 INSTALLATION
1. AC Input Power Connection
Connect the provided power cord into the input socket on the rear panel.
Before connecting to an electrical outlet, ensure the following:
a) The available line supply is compatible to your unit, meaning the voltage
and frequency must meet within the input specification operating range.
b) The available line supply is capable of supplying the maximum peak
current and power of the power supply.
WARNING: TO PROTECT THE OPERATORS, THE WIRE CONNECTED
TO THE GROUND TERMINAL MUST BE CONNECTED TO THE EARTH
GROUND. UNDER NO CIRCUMSTANCES SHOULD THIS AC SOURCE BE
OPERATED WITHOUT AN ADEQUATE GROUND CONNECTION.
2. Load Connections
A universal socket is provided on the rear panel for the output load
connections. Selection of Input Power and Load connection cabling should
follow good practice specific to the application. An output cable should be able
to handle the full load current and maximum voltage and power under worst-
case conditions of temperature, humidity, mechanical abuse, and effects of
long-term aging.
3. Turn-On
WARNING: BEFORE TURNING ON THE INSTRUMENT, ALL
PROTECTIVE EARTH TERMINALS, EXTENSION CORDS AND DEVICES
CONNECTED TO THE INSTRUMENT MUST BE CONNECTED TO A
PROTECTIVE EARTH GROUND. ANY INTERRUPTION OF THE
PROTECTIVE EARTH GROUNDING WILL CAUSE A POTENTIAL SHOCK
HAZARD.
a) Monitor the output voltage with a true RMS multimeter. Keep the
output ON/OFF switch to OFF position.
b) Turn the input power on through the input rocker switch. This will light
the front panel display. The display will show the model No. software
version No. , last set values of parameters, and the actual output
parameters.
c) There is a small delay between the time the last set values are
displayed until they are available on the output (Approx. 3 to 5
Seconds). After the output voltage has stabilized, set the voltage & the
frequency to the desired value & turn the output ON.
d) Load the output with a resistive load. If the output current exceeds the
maximum specified current limit, the alarm LED will turn on and output
will turn off (Overload trip) after some delay. This can be reset by
pressing the RESET button on the front panel.
