3.5. Water cooling unit (WCU)

The size of the WCU depends on the drive FS (see Section 3.2, "Drive frame sizes and
configurations", page 32). Both sizes have the same components:
– WCU800 has a cabinet width of 800 mm
– WCU1400 has a cabinet width of 1400 mm
In addition to the cooling system components (Fig. 20), a WCU has a low voltage compartment
section for power distribution and cooling unit control. For more information, see the WCU user
manual in "Appendix A – Additional manuals"; for information on the customer interface in the
WCU, see Section 6.8.2.1, "WCU - auxiliary power and space heater cable", page 109.
