•
Logic backup power is not designed to spin motors. It
is designed to maintain uninterrupted, low voltage power to
the motor electronics (encoder, DSP, communication, I/O, and
associated circuits).
•
Damage Warning: Reversing DC bus power polarity to
the Power Hub will permanently damage it. Use a
meter to verify correct DC bus power polarity before
connecting the power supply to the Power Hub.
•
Do not "hot swap" DC power connectors. Turn off DC
bus power supply before connecting a motor to the Power
Hub. Connecting and disconnecting the motor from a live
power supply will cause electrical arcing that will damage
the connectors over time.
•
Logic backup power should not be used as a means of
switching DC bus power on and off. To control DC bus
power, use a contactor on the AC side of the DC bus power
supply.
•
Do not connect more than two Power Hubs to a power
supply. Continuous and peak current usage must not exceed
the power supply's specifications.
It is the user's responsibility to ensure that the DC bus power
supply has sufficient continuous and peak power to meet
their application requirements.
•
Do not attempt to power more than four ClearPath
motors from a single Power Hub.

•
Any 3rd party (non-Teknic) power supply used with the Power
Hub, should be current limited or fused to 25A or less using
25A, 300VDC (UL Listed) fuses.
•
If UL compliance is a consideration, select a DC, UL Listed
fuse.
•
For those seeking a Class G fuse, the
SC-25 from Eaton Cooper
Bussmann
, or
OSLCO25 from Littelfuse
is recommended. Fuse
holders (also rated this way) include the
HPS-FF and TCFH30N
(from ECB/Littelfuse respectively)
