Edwards nEXT730D User Manual

CAUTION: ELECTRICAL SHOCK
Cont
act with live parts may lead to electrical shock.
The electrical connecon may only be carried out by a trained person. Observe the
naonal regulaons 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 interrupon of the protecve conductor system. In the event
of a fault, life-threatening voltages may be present on electrically conducve
components.
Before commissioning, check the resistance of the earthing cable and the suitability
of the assigned overcurrent protecon 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) connecons
Edwards recommend ng a separate earth (ground) conductor. Refer to Figure:
Connecons and controls. The impedance between the pump body and the earth
connecon point must be < 0.1 Ω.
5.4.2 TIC or TAG logic interface connecons
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 alternavely the customer power supply connected to the pump via the
dedicated nEXT pump power supply cable.
