Description / Overview
The cooling modules that are described in this instruction manual are part of a cooling unit
for the Schroff VARISTAR cabinet platform. In combination with the corresponding
VARISTAR cabinets, the cooling units are used to set up an enclosure.
Note
For the start-up of the cooling system, the cooling module must be connected to an
external re-cooling system (e.g. water chiller).
The unit is suitable for the use of water-glycol mixtures (33% glycol max.).
The power supply is ensured via a power supply unit. The power supply unit transforms
the mains voltage (AC, alternating voltage) into a direct voltage (DC) and it supplies
various components with power, including the control system and fans.
Since the fans are intended for a supply voltage of 48 V (DC), the cooling module can also
be used in telecommunications environments.
Note
See the circuit diagram.
The cooling modules are supplied as part of a Schroff VARISTAR cooling unit. The variants
and dimensions of the cooling units are configured based on the customer requirements
and VARISTAR cabinets that are used.
The following variants of the cooling modules are available:
•
60714-067: Cooling module, water connection at the bottom
•
60714-068: Cooling module, water connection at the bottom, redundant power
supply
•
60714-077: Cooling module, water connection at the top
•
60714-078: Cooling module, water connection at the top, redundant power supply
Note
•
Cooling modules with a redundant power supply are equipped with two power
supply units and mains power inputs. They can be supplied with power via two
independent mains power sources.
•
In the case of cooling modules with a water connection at the top, the condensate
outlet is also located at the top. These cooling modules are equipped with an
integrated condensate pump.
