… for the system space, and the refurbishment of sub-distributions to supply the refrigeration systems. To increase availability, the final circuits of the computing systems are monitored by RCM measurement systems. Two independent photovoltaic systems with an output of approx. 36 kWp each will be installed on the metal-clad gable roof. This includes the installation of a sub-distribution for the PV components (without inverters) as well as the installation of two distributions to accommodate surge protection devices. In addition, the cable support systems in the system room are adapted, the lighting fixtures are replaced and extensive cable and cable laying is carried out inside and outside the building. Generators must be provided to ensure availability during the conversion measures. In addition, the fire detection, access control and burglary detection systems are adapted to the changed structural space situation. The scope of services also includes the necessary testing and measurement work, the preparation of the audit documents as well as the ready-to-use commissioning and user instruction. ?
