5.1.4 Connection of the cooling system
The connection to the cooling system can occur as closed or open cooling circuit. The
connection to a closed cycle cooling circuit is recommended, because the danger of
contamination of coolant is very small. Preferably also a monitoring of the pH value of
the coolant should be installed.
Pay attention to a corresponding conductor cross-section at required equipotential
bonding in order to avoid electro-chemical procedures.
Otherelements in the coolingcircuit suchas pumps,shut-o󰀨valves,ventilation etc.
must be attached according to the cooling system and the local conditions.
