2. Installation and Wiring
2. Installation and Wiring
2.1 Installation
2.1.1 Installation Location
Since power supply unit is waterproof, you can install it outdoors. Be sure to install it
as close to the converter as possible.
Note:
Avoid installing the unit in ambient air containing excessive moisture or corrosive gas.
If the case cover is not closed tightly in excessive moisture or corrosive gas, the unit
may suffer problems such as insulation failure, disconnection, or poor contact.
2.1.2 How to Mount
Power supply unit can be mounted on bracket, pipe (nominal 50A size) or wall. How-
ever for pipe or wall mounting, order and use the optional mounting bracket. This
mounting bracket is supplied when specified.

2.2 Wiring
Indoors terminal board in power supply unit is connected by dedicated sensor cable
(used for wiring sensor to the DO402G).
CAUTION
When connecting the sensor to the terminals, match the colors, symbols, and numbers
described in the wiring diagram (it is packaged with the sensor cable).

2. Installation and Wiring
2.2.1 Connecting Sensor Cable
(1) Loosen two screws which are at front of power supply unit and detach the cover.
(2) Pull the cable into the power supply unit from sensor cable inlet hole.
(3) Connect the sensor cable to the terminals.
After passing the cable through the nut, check the color on each core wire, then
connect each core wire to the corresponding terminal.

(4) Mount the cable gland in the cable inlet hole.
Put the nut in place, and screw it onto the main body sufficiently. At this time,
loosen the packing gland so that the cable is not twisted. After fixing the main body,
tighten the packing gland to keep moisture out of the equipment. However if the
packing gland is screwed up too tight, the cable will be damaged.

3. Inspection and Maintenance
3. Inspection and Maintenance
Normally, it is sufficient to inspect the DOX10 power supply unit during periodic
system repairs (once a year or every two years), as fan as it works without fail. Daily
inspection and maintenance are not required.
3.1 Power Supply Unit Inspection
3.1.1 Checking for Moisture and Performing the Required Maintenance
Remove the cover of the terminal box and check for moisture. If the inside is very
damp, use a hair drier to dry the inside of the box.
3.1.2 Checking for Corrosion and Performing the Required Maintenance
Check that corrosive gas has not entered the terminal box and corroded the terminals
and conductors. If the corrosion is excessive and problems such as poor contact and
disconnection seem likely, replace the corroded apparatus.
