General Information

2.1.3 Chemical and Biological Safety

DANGER

Potential danger with contact with chemical/biological substances.
Working with chemical samples, standards and reagents can be dangerous.
Make yourself familiar with the necessary safety procedures and the correct handling of the chemicals before use

and read and follow all relevant safety data sheets.

Normal operation of this device may require the use of chemicals or samples that are biologically
unsafe.

• Observe all cautionary information printed on the original solution containers and safety data
sheets prior to their use.

• Dispose of all consumed solutions in accordance with the local and national regulations and
laws.

• Select the type of protective equipment suitable to the concentration and quantity of the
dangerous material being used.

DANGER

The BIOGAS Titration Manager has been developed to meet the requirements of volumetric titration applications.
It is therefore aimed at experienced users who have the knowledge required to operate the instrument and imple­ment the security instructions enclosed. Please remember that the BIOGAS Titration Manager must not, under
any circumstances, be used to perform tests on living beings.

WARNUNG

The BIOGAS Titration Manager may not be used in dangerous environments.
The manufacturer and its suppliers reject any express or indirect guarantee for use with high-risk activities.

Follow the following safety information, in addition to any local guidelines in force.

Safety information for the correct use of the instrument:

• Do not vibrate or jolt the instrument.

• Do not open the instrument.

• Guarantee is voided if the instrument is not used in accordance with the guidelines present in

this document.

ACHTUNG

The manufacturer is not responsible for damages resulting from misapplication or misuse of this product and
rejects the regulation of such damages, including direct, indirect and consequential damages, and in full
accordance with applicable law. The user is solely responsible for the identification of critical applications and risks
and taking appropriate measures to protect processes during a possible equipment malfunction.

3.3 Power connections

Use only a grounded socket for the connection of this device to the power supply. If you are not sure if the sock­ets are grounded, have this checked by a qualified electrician. The power plug serves in addition to the power
supply to isolate the device quickly from the power source where necessary. During the disconnection from the
power source it must be made sure that the correct power plug is pulled (for example by labeling the sockets).
This is recommended for long-term storage and can prevent potential dangers in the event of a fault. Therefore
make sure that the socket to which the device is connected is easy to reach by each user at all times.

WARNING

Electrical dangers and fire hazard.
Only use the supplied power cable.

Figure 1 Power connection

NOTICE

1 Power connection

1. Plug the power cable into the back of the instrument (Figure 1).

2. Insert the plug of the power cable into a grounded mains socket (100–240 V~ / 50–60 Hz).

3. Switch the power button to "On" to turn on the instrument (Figure 2, position 13).
