Safety Information COMtrexx Business
To ensure that you are able to use the device safely and without faults, comply with the notes below. Improper use may, for example, cause functional restrictions, destruction of the device or, in a worst case scenario, personal injury. You will find any necessary additional warning notices about using the device in the relevant sections.
Read the instructions for the device and keep them for future reference.
Connecting Safely
Ensure you comply with the relevant regulations when handling supply voltage and devices attached to the mains.
Connect the device as described in these Instructions. Take note of the technical data on the type plate and in these Instructions.
Only connect the device's connection cables to wall sockets that are designed for that purpose, and that have been properly installed.
Only use original accessories and original replacement parts.
Only work on active, contact-hazardous parts after a voltage-free condition has been established. Working near active parts is only permitted if these parts are voltage-free or protected against direct contact.
Pull out the device's power plug before instructing a qualified electrician to open the casing to install the expansion module, or switch or connect equipment. Also disconnect the devices from additional power sources (e.g. UPS, if installed).
Wait for any capacitors to discharge. The electrolytic capacitors of the switching power supply or the ringer voltage can still be charged for a longer period of time even after the power plug has been pulled out or in the event of a power failure.
Do not touch the device or any equipment connected to it during a thunderstorm.
Divert electrostatic charges away from yourself before touching the circuit boards with your hands or the tool. To do this, touch an earthed metallic object, such as the device's earthing terminal or a PC casing.
Hire a qualified electrician to lay the cables within the building – including the cable to the door terminal.
Safe Use
Only operate the device when the casing is closed.
For some installation and maintenance work, it is necessary to open the device while it is in operation (this should only be done by a qualified electrician). Make sure that the device is never left unattended while working with an open casing.
Only operate the device when it is securely fastened in a 19" rack.
Never cover the air vents of the casing.
Protect the devices by installing overvoltage protection.
If possible, provide a separate electric circuit for the connection that supplies the COMtrexx.
Location Characteristics
Only operate the PBX in closed, dry rooms.
Mount the device close of an earth wire (potential compensation bar of the house installation or protective earth conductor). Connect the COMtrexx's earth connection with a connecting cable whose conductor diameter is at least 2.5 mm2 to the earth wire.
Do not expose the device to direct sunlight.
Avoid mechanical loads (e.g. vibrations).
Avoid the vicinity of devices that emit electromagnetic fields or react sensitively to them (e.g. radio receivers, professional radio equipment, amateur radio equipment, mobile phones, DECT systems, etc.).
Protect the device from dirt, excessive dust and condensation.
Note the values given for ambient temperature and humidity in the technical data.
Prevent unauthorized access to the COMtrexx and its programming. This device is not suitable for use in places where children may be present.
Limitations on Use
Do not operate a damaged device.
Do not touch the device or any equipment connected to it during a thunderstorm.
Do not use the device for life support systems or applications inside nuclear facilities. Before using the product for such applications, it is imperative that you obtain the manufacturer's written approval/declaration in each individual case.
Do not make any structural changes to the device.
Necessary Knowledge for Configuration
Only a qualified electrician may open the casing, perform installation work within an open casing or service work using the buttons inside the casing. If necessary, commission an authorised dealer to perform this work.
Incomplete or incorrect configuration can create a personal hazard e.g. because emergency calls cannot be made.
The configuration of the product is made via an integrated web server whose pages are called via web browser. The user interface of the web server (web interface) is available in German, English and French. The detailed operating instructions (online help) is provided in German and English. If you are not familiar with these languages, and the technical terms that are used, seek support from someone who has the necessary technical and language skills.
Repair
Unauthorised changes to the device can damage the device or breach security and EMC regulations. Have repairs carried out by qualified personnel only. Please contact your qualified electrician or contact the manufacturer directly.
Cleaning
Warning: Any liquid that penetrates the casing can result in a life-threatening electric shock or can damage or destroy the telephone.
•Only clean the device with a soft damp cloth or an anti-static cloth.
Data protection
Take suitable measures for protecting your data and the PBX against misuse.
Never tell anyone the user names, passwords or PINs. This applies to postings in forums and communities, router service logs or recorded network protocols.
Consistently use all available options for assigning passwords and PINs. Do not use passwords and PINs that are easy to guess, such as birthdays or anniversaries.
Use the available permissions (programming authorisation, exchange line authorisations, restricted numbers, etc.).
Regularly check the call data recording of your COMtrexx and, if necessary, the logs of your NAT router for discrepancies.
Additional information about protecting the system from misuse can be found in the internet on the pages of the German Federal Office for Information Security (see
