WirelessHART Fieldgate SWG70 Safety
E Hauser 7
When installing components in explosion hazardous areas:
• Ensure that all installation and maintenance personnel are suitably qualified.
• Check that all equipment has the appropriate safety certificates.
• Observe the specifications in the device certificates as well as national and local
regulations.
Coexistence of wireless
technologies
WirelessHART networks use the frequency spectrum between 2400 ... 2483.5 MHz accord-
ing to IEEE 802.15.4. Various other wireless technologies also use this frequency spectrum,
for example WLAN and Bluetooth. Depending upon the situation, it is possible that these
different wireless technologies will affect each other.
When wireless technologies are used in an industrial environment, they must coexist with-
out interfering with each other. If you find that systems are interfering with each other, take
appropriate measures to ensure the operation of all wireless systems, e.g. by reconfiguring,
enforcing a wireless compatibility policy, etc.
Operation Caution!
Maintain a minimum distance of 20 cm between the device antenna and the body of the user
and all persons in the vicinity at all times and for all applications and uses.
1.4 IT security
The Fieldgate SWG70 is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings. Additional IT security measures in line with
operators' security standards and designed to provide additional protection for the device
and device data transfer must be implemented by the operators themselves.
The Fieldgate offers the following functions that increase IT security:
• WirelessHART security management (See Chapter 3.2.2 "WirelessHART security
management" on page 13 and see Chapter 8.2.1 "Basic Setup" on page 45.)
• Password for Web server (See Chapter 11.4 "Change Password (Web Server)" on
page 105.)
• Security certificate for Web server (See Chapter 11.7 "Upload Certificate (Web server)" on
page 107.)
See the Technical Information "WirelessHART Fieldgate SWG70" (TI00027S) on the
CD-ROM provided for system-specific firewall configurations such as TCP/IP ports and
services.
