5.4 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-off valves, ventilation etc.
must be attached according to the cooling system and the local conditions.

Straight screw-in connection, cutting rings and union nuts (e.g. from Parker Er-
meto) can be used for the connection of the cooling system.
KEB recommends the use of a flow switch in order to monitor the flow in the
cooling system.
