Scope
This change concerns ACS800 Liquid-cooled multidrive Units (ACS800-107LC, -
207LC, -307LC, -507LC, -607LC, -1107LC, -1207LC), ACS800-1007LC Liquid
Cooling Unit, ACS800-07LC Drives, ACS800-17LC Drives and ACS800-37LC
Drives manufactured in Finland or Estonia.
New units and drives are tested with Antifrogen® L. Antifrogen® L is a ready-made
propylene glycol based coolant mixture with corrosion inhibitors included. Proper
selection of Antifrogen® L and Adjustment of the Main Choke Valve is described in
the document Usage of Antifrogen® L in ACS800LC Drives (3AXD10000511935).
New units and drives which are tested with Antifrogen® L must be operated with
Antifrogen® L to prevent corrosion in the system. If usage of the old propylene glycol
and corrosion inhibitor Cortec VpCl-649 in new Antifrogen® L tested units and drives
is wanted system must be flushed before as Antifrogen® L remains in the system
after testing. Flushing procedure described in the document Usage of Antifrogen® L
in ACS800LC Drives (3AXD10000511935) must be followed. If new units or drives
tested with Antifrogen® L are connected to old ACS800 industrial liquid-cooled units
or drives, both systems needs to use same the coolant. Mixing propylene glycol and
corrosion inhibitor Cortec VpCl-649 coolant with Antifrogen® L is not allowed.
New units and drives are tested with Antifrogen® L are labelled with information
label (3AXD50000431427) below. The label is installed to LCU-cabinet or incoming
main pipe of the unit if delivered without LCU-cabinet.
This update notice and Usage of Antifrogen® L in ACS800LC Drives
(3AXD10000511935) document are delivered with drive in documentation pocket
inside the cabinet door.
