7.4 Water connections and water flow rate
The devices have the following outside port diameters. To ensure a reliable operation, the water flow rate ac-
cording to Tab. 7.2 on page15 is required. When the minimum flow rate is not met, the laser will be turned
off if a safety interlock is connected.
