3. INSTALLATION
Warning:
This equipment is provided with a protective earthing ground incorporated in the power cord.
The main plug shall only be inserted in a socket outlet provided with a protective earth contact.
Any interruption of the protective conductor, inside or outside the instrument, is likely to make
the instrument dangerous. The type of main plugged shipped with each instrument depends
on the country of application.
Caution:
Do not connect AC power until you have verified that the line voltage is correct and the proper
fuses are installed. The equipment requires a power source of either 50/60 Hz at 110V or
50/60 Hz at 240V. The voltage ranges for these nominal voltage values are shown in the
table:
POWER REQUIREMENT
Input voltage 90-260 Vrms auto select
Frequency 47 to 63 Hz
Power 50 VA max. / 30 VA typical.
Current 110 V/0.27A or 240 V/0.125A typical
Caution:
Be sure the supply voltage is within the specified range.
Checking the fuses:
The recognized recommended fuses are size 5 by 20 mm, rate T 2.0A, 250 V (UL and IEC
approved).
The line fuse is housed in a small container besides the power connector on the rear panel.
To check the fuse, insert the tip of a screwdriver in the slot at the middle of the container and
pry gently to extend the fuse where there is a little tap and pull out the fuse gently. The fuse is
attached to the line module and cannot be removed.
3.1 Inspection and Test
Check if the devise has any visible damage. If everything seems all right, power can be
applied to the device. The main socket and fuse are located at the rear panel of the device.
When the device is turned on, verify that the display shows the following message:
DCH-4000P (factory default unit-name)
IP: 168.192.1.21 (factory default IP Address)
If no message is shown in the display or there is not light in the display, the device is

defective and has to be returned for servicing.
3.2 Functional Self Test
No specific functional self test is needed.
The device has been factory tested according to recognized test procedures and is ready for
operation.
3.3 Mounting
The environment should be relatively dust free, free of excessive vibration and the ambient
temperature between 0 ℃to 40 ℃. Relative humidity of 20% to 80% (non-condensed) is
recommended.
Air intake for cooling is achieved via holes at the side of the device and the fans inside. The
air flow should not be obstructed. Therefore, the device has to be placed on a flat surface,
leaving some space at the sides of the device.
When in operation, the internal temperature should not exceed the limit of 70 ℃.
