affecting operation
WARNING
11-8
The following values apply to units of K type of construction:
Fan voltage / frequency
Fan power requirement
Flow
Sound-pressure level IP00
Sound-pressure level for chassis in
IP20 - cabinet
Sound-pressure level for chassis in
IP42 - cabinet with dust filter,
400 mm high cabinet cover
Condition for sound-pressure measurement:
♦ Room height: 6 m
♦ Distance to next reflecting wall: 4 m
The unit is to be connected to an existing external cooling-water circuit.
The construction of this cooling-water circuit under the aspects of
♦ open or closed circuit
♦ choice and juxtaposition of materials
♦ composition of cooling water
♦ cooling-water cooling (recooling, supply of fresh cooling water)
♦ and others
have an important effect on the safe functioning and service life of the
whole installation.
The warnings given under "Standard units" apply.
Installation and servicing work on the water cooling system must be
performed with the power disconnected.
There must be no condensation on the units (also applies to standard
units).
