FK1 and FK2 Fan Kit
The FK1 and FK2 Fan Kit Option may be necessary if air flow across the B896n
heat sink is extremely poor, or if the ambient temperature is excessive.The FK1
and the FK2 are the 110VAC and 220VAC versions of IDC’s fan kit.They can be
ordered individually for drive mounting in the field,or ordered as part of a system
(i.e.B8961-FK2) for factory mounting.Since the B896n supplies power to the fan
no additional wiring or mounting is required.
See Appendix C for additional information on the fan kit,including mounting
dimensions.
RPACK-1 and RPACK-2 Mounting Installation
The RPACK-1 and the RPACK-2
are packaged power dump
devices consisting of high
voltage power resistors, a
heatsink and a cooling fan.
They are accessories to IDC’s
B Series controls.The RPACK-1
has a 1 1 0 VAC fan while the
R PAC K - 2 has a 220VAC fan.
Please note that unlike a fa n
k i t , the RPAC K is a standalone
box that does not share a
power supply with the B8001.
An RPACK is typically used
when it is necessary to very rapidly decelerate heavy vertical loads or large inertial
loads.The RPACK-1 dissipates the kinetic and potential energy that would other-
wise cause the drive to shutdown due to an Over-Voltage or Regen fault.Using an
RPACK-1 can help reduce overall cycle time by allowing a higher deceleration rate
than would be possible without it.
See Appendix D for additional information on the RPACK,including mounting
dimensions.The recommended panel spacing is also the same.Electrical connec-
tions should be made according to the diagram above.
