Earth (Ground) Connections; Tic Or Tag Logic Interface Connections; Figure 19 Controller View - Edwards nEXT730D Instruction Manual

CAUTION: ELECTRICAL SHOCK
Contact with live parts may lead to electrical shock.
The electrical connection may only be carried out by a trained person. Observe the
national regulations in the user country, e.g. for Europe EN 50110 - 1. Prior to
servicing, disconnect the vacuum pump from the power supply.
Electrical shock due to interruption of the protective conductor system. In the event
of a fault, life-threatening voltages may be present on electrically conductive
components.
Before commissioning, check the resistance of the earthing cable and the suitability
of the assigned overcurrent protection device.
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
Connections and
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.
