Epsilon Eb Digital Servo Drive Installation Manual
Line Fusing and Wire Size
You must incorporate over current protection for the incoming
AC power with the minimum rating shown below. EMERSON
Motion Control recommends Bussman type: KTK-R, KTK, LPN
or equivalent.
This inrush current specification assumes the drive has been
powered off for at least eight minutes at 40° C ambient or five
minutes at 25° C ambient. If this amount of time has not
elapsed since power off, the inrush current will be higher.
Input Power Connections
Power must be "Off" for a minimum of 6 minutes for the
Epsilon drive before unplugging the power connection, to
ensure the bus voltage has bled down to a safe level (below 50
VDC).
