4 Safety instructions 1 Safety instructions General Identification of safety instructions These operating instructions contain general information that must be observed during installation, operation and maintenance. They must therefore be read by the installer and relevant qualified technician(s) prior to installation and commissioning. They must always be available at the system. Failure to observe the safety instructions identified with this hazard symbol in these installation and operating instructions may result in risks to personnel. Caution Failure to observe the safety instructions identified with this symbol may result in risks for the device or the system and its functions. Note This symbol indicates information that will simplify work and ensure safe operation. Personnel qualifications Risks from failure to observe the safety instructions The personnel designated to operate, maintain, inspect and install this equipment must have the appropriate qualifications for such work. The system operator is responsible for ensuring that this is the case. The safety instructions listed in these operating instructions must be observed, as must all applicable national regulations for accident prevention and any in-house working, operating or safety instructions issued by the operator. Failure to observe the safety instructions may result in risks to personnel as well as to the environment and the system. LIABILITY The manufacturer will not accept any liability if these safety instructions are not observed. In particular, failure to observe these instructions may pose the following risks: Failure of important system functions Failure of prescribed methods of service and maintenance Risks to personnel due to electrical and mechanical effects Safety instructions for the operator (risk analysis according to EN 12100) Safety instructions for maintenance, inspection and installation work Electrical hazards Hazards arising from electrical current, e.g. as a result of removing safety covers, must be prevented. The operator must ensure that all maintenance, inspection and installation work is carried out by authorised, qualified personnel who have used the operating instructions to acquaint themselves with the device. In principle, work may only be carried out on the device when the CHP unit is in an idle state and isolated from the power supply. Directly after work has been completed, all safety and protective equipment must be replaced and returned to full function. 4 CHP unit accessory Installation and operating instructions BACnet/IP Gateway VITOBLOC 200
