NINA-W1 series - User Manual
device. If the device implements a removable antenna, the antenna port can be separated from the
enclosure port. The antenna port includes the antenna element and its interconnecting cable
surfaces.
The applicability of ESD immunity test to the whole device depends on the device classification as
defined by
ETSI EN 301 489-1
. Applicability of ESD immunity test to the related device ports or the
related interconnecting cables to auxiliary equipment, depends on the device accessible interfaces
and manufacturer requirements, as defined by the
ETSI EN 301 489-1
.
Contact discharges are performed at conductive surfaces, while air discharges are performed at
insulating surfaces. Indirect contact discharges are performed on the measurement setup
horizontal and vertical coupling planes as defined in the
CENELEC EN 61000-4-2
.
For the definition of integral antenna, removable antenna, antenna port, and device classification,
refer to the ETSI EN 301 489-1. For the contact and air discharges definitions, refer to CENELEC EN
61000-4-2.

NINA-W1 is manufactured taking into account specific standards to minimize the occurrence of ESD
events; the highly automated process complies with the IEC61340-5-1 (STM5.2-1999 Class M1
devices) standard. Thus, the designer should implement proper measures to protect from ESD
events on any pin that may be exposed to the end user.
Compliance with standard protection level specified in the EN61000-4-2 can be achieved by
including the ESD protections in parallel to the line, close to areas accessible by the end user.
