Installation

This section shows how to install and connect the DPI 104.
Before you start:
• Read and understand the "Safety" section.
• Do not use a damaged DPI 104.
Installation - Battery
A1.2
Use the procedures in Table 1 to install or replace the

battery.

Table 1: Installation procedures - Battery
Step Procedure
1 If applicable, set the power to off and isolate the
external power supply.
2 Remove the display bezel (Figure A1.2).
3 Make sure that the o-ring [A1: item 7] and the related
surfaces are serviceable. Use only original parts
supplied by the manufacturer.
4 Remove the battery clamp [A1: item 10].
5 If applicable, disconnect the battery connector
[A1: item 8] and *discard the used battery.
6 Attach the battery connector [A1: item 8] to the new
battery.
7 Install the new battery (Figure A1.3) and re-attach
the battery clamp [A1: item 10].
8 Push the display bezel [A1: item 6] back into position
until it is fully engaged.
* Use an applicable recycling facility.
Installation - Position
Make sure that you attach the DPI 104 in a safe
configuration that prevents unwanted stress (for example
vibration, physical impact, shock, mechanical and thermal
stresses).
To get the best installation position, you can turn the
pressure connector (A1: item 4) and the display bezel
(A1: item 6) to give the best view of the display (Figure B1).
End stops set the limits in each axis.
CAUTION: To prevent damage when you are setting the
best view of the display, do not use force to turn the
pressure connector or the bezel farther than the end
stops.
Installation - Pressure connections
CAUTION: To prevent damage, do not use the body of the
DPI 104 to tighten the pressure connection. Use the flat
faces on the pressure connector.
Use an applicable method to seal the pressure
connections, and then tighten to the applicable torque
(Figure 1 and Table 2).

These optional accessories use the connector:
• RS232 PC connection
• external IDOS UPM connection + power supply adaptor
Note: Use only original parts supplied by the manufacturer.
You can also use the RS232 interface to make a serial
network of units (maximum: 99). Refer to "Operation - Set
up a DPI 104 network".
Electrical connections - External power
We recommend you use an external power supply for
these functions and operations:
• Functions: Maximum/minimum, Switch,
Low/high alarm, Vout, IDOS
• Operations that use the DPI 104 for long periods
