General safety points Instruction Manual ColorPlus 3
14501E/2 17
3General safety points
3.1 Dangers when properly used
DANGER!
Damaged instrument or cabling.
Touching damaged cables may lead to electrical shocks or death.
The instrument may be operated only when the cables are undamaged.
The instrument may be operated only if it has been properly installed or repaired.
DANGER!
Dangerous voltage inside the instrument.
Touching live components inside the instrument may lead to electric shocks resulting in
death.
The instrument must not be operated when the housing is removed or opened.
DANGER!
Damage to the instrument due to incorrect service voltage.
If the instrument is connected to an incorrect service voltage, the instrument can be dam-
aged.
The instrument may be connected only to voltage sources as specified on the rating
plate.
DANGER!
Missing Instruction Manual after the instrument changes hands.
Operating the instrument without knowledge of the Instruction Manual may lead to injuries
to persons and damage to the instrument.
If the instrument changes hands, always include the Instruction Manual.
If the Instruction Manual is lost, you can request a replacement.
Registered users can download the current version at www.photometer.com.
CAUTION!
Escaping medium from leaks on the instrument or water connections.
Escaping medium can lead to flooding of the room and material damage to the building and
fittings.
Check that there are no leaks.
DANGER!
Manipulations on pressurized lines.
Improper manipulations on a pressurized line can lead to the sample escaping under pres-
sure, resulting in injuries, damage to the instrument and material damage on site.
Always consult the Instruction Manual before making any manipulations to pressurized
lines.
The medium line must be emptied before removing the instrument or opening the
measuring cell.

Instruction Manual ColorPlus 3 General safety points
18 14501E/2
CAUTION!
Eye injuries caused by UV radiation.
During operation, there is dangerous UV radiation that can cause eye damage.
Always interrupt the service voltage before opening the instrument.
Never look directly into the light beam.
Do not use any reflective objects when cleaning the measuring cell.
CAUTION!
Penetration of moisture as well as condensation on the electrical components dur-
ing servicing duty.
If moisture enters the instrument, the ColorPlus 3 can be damaged.
Work inside the instrument may be performed only in a dry room and at room tempera-
ture. The instrument should be at operating or room temperature (avoid condensation
on optical and electrical surfaces).
CAUTION!
The use of aggressive chemicals when cleaning.
Use of aggressive chemicals can cause damage to instrument components.
Do not use aggressive chemicals or cleaning agents when cleaning.
Should the instrument come in contact with aggressive chemicals, clean it thoroughly
with a neutral cleaning agent.
3.2 Residual risk
WARNING!
According to the risk assessment of the applied safety directive DIN EN 61010-1,
there remains the risk of the displayed measuring values being incorrect. This risk
can be reduced with the following measures:
Use an access code to prevent unauthorized persons from changing parameters.
Perform the specified servicing duties.
3.3 Warning and danger symbols on the instrument
WARNING!
There are no warning or danger symbols on the instrument.
Users must ensure that they observe the safety measures as specified in the Instruction Man-
ual at all times when working with the instrument and its peripheral equipment, even if no
warning or danger symbols are attached to the instrument.
The following sections must be internalized:
Section 1.11
Section 1.12
Section 1.13
Section 3.1
Section 3.2
Observe safety pointers when performing the described procedures.
Observe local safety pointers.

General safety points Instruction Manual ColorPlus 3
14501E/2 19
3.4 Preventing undesirable online access attempts
WARNING!
SIGRIST instruments are equipped with an integrated web user interface and Mod-
bus TCP interface, thus offering state-of-the-art administration and control possibil-
ities. However, if these are connected directly to the Internet, then any Internet us-
er can in principle access your instrument and change the configuration.
Please note the following points to prevent this:
Never connect the instrument directly to the Internet.
Operate it behind a firewall and block access to the instrument.
Only connect to branch offices via VPN.
Change the standard password on commissioning.
Always keep up to date with the latest changes regarding Internet security so that you
can react promptly in the event of alterations.
Install the latest updates immediately (also for the router and firewall).

4Mounting
4.1 Mounting the ColorPlus 3
Note the following points when mounting the instrument:
The ColorPlus 3 must be installed horizontally. The sample outlet (Y) must be positioned
at the top so that the measuring cell can be well ventilated.
A regulator valve must be installed on the sample outlet (Y) so that counter pressure can
be generated (operation of the measuring cell under pressure so that disruptive air bub-
bles are eliminated).
Mount the ColorPlus 3 as follows:
WORKSTEP
ADDITIONAL INFO / IMAGES
1.
Install the ColorPlus 3 horizontally onto a wall
using two M6 screws on the fastening plate.
2.
Connect the hoses (D = 8 mm) to the sample
inlet and outlet.
