Turn-On Checkout Procedure
WARNING
There is a potential electrical shock hazard when using a power supply without output protection. Do
not turn ON power without output protection properly assembled. Turn OFF power supply or
disconnect power supply from AC mains before making or changing any rear panel connection.
WARNUNG
Wenn ein Netzgerät ohne Berührungssschutz benutzt wird, besteht die Gefahr eines Stromschlags.
Schalten Sie das Gerät nicht EIN, wenn der Berührungssschutz nicht ordnungsgemäß angebracht
ist. Schalten Sie das Netzgerät AUS oder trennen das Netzgerät vom Versorgungsnetz ab, bevor
Sie irgendwelche Anschlüsse an der Geräterückseite vornehmen oder ändern.
4.8.1
General
The following procedure ensures that the power supply is operational and may be used as a basic
incoming inspection check. Refer to Figure 2-1 and Figure 2-3 for the location of the controls indicated
in the procedure. Please note that this procedure is valid for standard units. For blank units, all the
parameters settings and status reading can be made by using communication interfaces. Refer to the
User manual for further information.
4.8.2
Prior to Operation
1. Ensure that the power supply is configured to the default setting (refer to User Manual IA761-04-
02_, Parameter Setting Memory section):
2. Power On/Off switch at Off position.
3. Ensure that the protection of output terminals is mounted and properly assembled.
4. Connect the unit to an AC source as described in Section 4.7.
5. Connect a DVM with appropriate cables for the rated voltage to the output terminals.
6. Turn the front panel Power switch to On.
7. When power supply is turned ON and all LCD Display segments and LEDs illuminate
momentarily, then the LCD display shows: ”
OUT OFF
” (not applicable to Blank Panel power supply).
8. The power supply operating status is then displayed (not applicable to Blank Panel power supply).
4.8.3
Constant Voltage Check (Standard Power Supply)
1. Turn on the output by pressing OUT button so the OUT LED illuminates.
2. Observe the power supply Voltage display and rotate the Voltage encoder.
3. Ensure that the output voltage varies while the Voltage encoder is rotated. The minimum control
range is from zero to the maximum rated output for the power supply model.
4. Compare the DVM reading with the front panel Voltage display to verify the accuracy of the
Voltage display.
5. Ensure that the front panel CV indication on the LCD screen is active.
6. Turn off the front panel Power switch.
