The nEXT pump can be controlled using the Edwards TIC Turbo Instrument Controller,
TIC Turbo Controller or TAG Controller or a customer system. The nEXT pump can be
powered by the Edwards power supply or by a customer power supply via the nEXT
pump power supply cable.

5.4.1 Earth (ground) connections
Edwards recommend fitting a separate earth (ground) conductor. Refer to Figure:
Connections and controls. The impedance between the pump body and the earth
connection point must be < 0.1 Ω.
5.4.2 TIC or TAG logic interface connections
If an Edwards TIC Turbo Instrument Controller, TIC Turbo Controller or TAG Controller are
used to control the pump, the nEXT pump logic interface cable connects directly into the
back of the TIC or TAG, and the nEXT pump is powered separately using the Edwards
power supply or alternatively the customer power supply connected to the pump via the
dedicated nEXT pump power supply cable.
The RS485/CAN/RS232 slide switch must be in the RS232 position if either the TIC or TAG
is to be used to control the nEXT pump.
5.4.3 Connect the logic interface to control equipment
To operate the pump using your own control system, use suitable connector mating half
(not supplied) to connect the control equipment to the connector on the logic interface
cable.
