Daisy Chaining
Daisy chaining allows up to 5 Horizon Nxt® or Horizon® pumps to be
plugged into each other with only one pump plugged into a wall outlet. On
the side of each Horizon Nxt pump is an electrical outlet. Only another
Horizon or Horizon Nxt pump should be plugged into that outlet.
Caution:
To daisy chain more than 5 pumps, verify that the total leakage
current as a system does not exceed 100 uA.
Battery Operation
The Horizon Nxt has been equipped with an internal, rechargeable battery
which will power the pump automatically if the plug is disconnected during
use. Battery power is provided as a back-up system only, and the length of
the battery life is affected by the rate of delivery. Whenever possible, the
pump should remain plugged into an electrical outlet. The Battery Use
indicator will be lit when the pump is operating on its battery.
The pump must remain plugged into a hospital-grade electrical outlet for at
least 24 hours to fully recharge the battery from a totally discharged
condition.
