Connecting AC power
Use an AC power cable that is appropriate for the power scheme in your country
or region:
!
For applications in Europe
, use a harmonized AC power cable. The
universal power supply of the terminal automatically senses the voltage from
the external source and, within the range 115 to 230 VAC, 50 to 60 Hz,
supplies the appropriate power without requiring any adjustment.
!
For North American applications , use a standard AC power cable
(Figure 4)
.
Both types of AC power cable are available from 3M Touch Systems and come
with either:
!
IEC connector
or
!
Fixed field wiring
Connecting AC power: Using cable with IEC connector
To connect the power supply using a cable with IEC connector, follow these steps:
1. If the terminal has a hatch , make sure that the hatch is open. The hatch
must be open to access connectors.
2.
Connect the AC power cable with IEC connector to the power socket inside
the rear hatch of the terminal (Figure 3).

WARNING
To reduce the risks associated with electrical shock or fire which, if not avoided,
could result in death or serious injury and/or property damage:
!
To ensure compliance with electrical codes and safe operation of the ET unit, have a
licensed journeyman electrician familiar with local codes perform all wiring tasks.
!
Install the ET unit close to the power source so power to the ET unit can be removed
quickly and easily. For permanently connected equipment, a readily accessible
disconnect device must be incorporated into the fixed wiring.
!
Provide adequate strain relief for all communications and power cables.
!
Before removing the ET unit from its mounting or performing any other service to the unit,
disconnect power to the unit.
