1-5 Installation
1-5-1 Installation Conditions
When installing the unit, observe the following items.
Set the unit on a level place to use.
Secure a space at least 30 cm and more in front and back of the unit not to block air inlet
and outlet.
Secure air inlet and outlet on the external cabinet as the same size as the air inlet and
outlet of the unit.
When installing the unit in a closed cabinet, mount forced exhaust to prevent exhaust
heat from returning to the air inlet.
If dust collects in the air inlet, remove it immediately. It prevents the unit from cooling.
Do not place anything on top of the unit.
Do not expose the unit for overly aggressive environments such as salt mist, corrosive or
explosive gases, steam, or dust.
Do not install the unit in a place where condensation may occur.
Prevent liquids or metals from entering the unit through the air inlet and outlet.
It may result in malfunction, electric shock, or fire.
The unit is designed for a 19-inch rack. Support the chassis with the guide rails of a rack
when installing the unit. Never support the unit only with the mounting holes on the front
panel.
The handles on the front panel are used to change the direction of the unit or pull out the
unit mounted in a rack. Avoid any application that the entire weight of the unit is applied to
the handles on the front panel.
1-5-2 Ventilation
The front and back sides of the unit are air inlet and outlet for cooling air respectively.
Secure a space for good ventilation to use the unit.
If dust collects in the air inlet, remove it immediately.
If dust collects in the air inlet, it may results in malfunction due to less cooling.
1-6 Points to be careful about in handling.
WHEN TOUCHING LOAD AFTER TURNING OFF THE OUTPUT
1. Make the setting of an output voltage to zero (0).
2. Turn off the OUTPUT switch.
3. Check that the voltage is zero on the display.
4. Turn off the POWER switch.
5. Ground the output for more than 10 seconds, and then check that the voltage is zero with another
high voltage meter.
It is especially dangerous that the load is capacitive or a long cable is used.
6. Make it a rule to touch load with right hand.
How to ground
Use an outlet with a ground terminal.
Improper grounding may result in electric shock.
