Rockwell Automation 7000L PowerFlex Medium Voltage AC Drive (C Frame) - Classic Control - Manual (Page 21)

Overview of Drive 1-3
7000 “C” Frame 7000L-UM300I-EN-P – June 2013
 Integral pumping panel includes:
– Line supply c/w disconnect and fusing
– Closed loop coolant system
– Iron and chloride free liquid ethyl-glycol / de-ionized water
mixture
– Low conductivity coolant (1-2 micro-Siemens / cm 3 )
– Isolated from medium voltage
– Fully serviceable low voltage compartment isolated from
medium voltage power
– Monitors coolant temperature, flow, level, conductivity, and
pressure
– Redundant pumping system
– Automatic pump change over on pump failure
– 1/2 turn valves with quick disconnect couplers for pump
replacement when drive is operating
– Full drip tray to contain any spilled coolant
– Drain and fill pump for convenient filling
– Industrial schedule 80 CPVC piping for pump panel, headers
and manifolds (no condensation possibility)
– Control hardware for cycling of main / redundant cooling
pumps and Heat exchanger fans
 “Plug and play” Power Cage concept
– Central location for easy access to all main power
components
– Common modular design for rectifier / inverter
– Same concept as air cooled drive for front access, easy
component replacement, and no special tools
– 5-10 minutes to replace main power devices
– No need to remove any cooling lines for device replacement
– Reduced manufacturing time for faster delivery and lower
cost
 Keyed mechanical interlock
– Interlocked with main disconnect means to prevent unsafe
access to medium voltage section
