Section 2: Installation and Setup
Installation consists of mounting WebRelay-10 Plus™, connecting it to an Ethernet network, providing power,
conguring via a web browser, and wiring relay contacts to the device that will be controlled.
For WebRelay-10 Plus™ models, inputs and sensors can be wired to the device using the 5-position terminal
connector.
Installation Guidelines (Read Before Installing)
• This unit must be installed by qualied personnel.
• This unit must not be installed in unprotected outdoor locations.
• The WebRelay-10 Plus™ must installed inside an NRTL certied industrial control panel or similar NRTL
certied re/electrical enclosure.
• If the WebRelay-10 Plus™ is used in a manner not specied by Xytronix, the protection provided by the
equipment may be impaired.
• This unit must not be used for medical, life saving purposes, or for any purpose where its failure could
cause serious injury or the loss of life.
• This unit must not be used in any way where its function or failure could cause signicant loss or property
damage.
• The relay tab terminals are 1/4” x .032”. Use UL listed quick-connect connectors suitable for eld
connections. Use a suitable crimping tool as specied by the connector manufacturer. Use wire rated for
75ºC (min) for connections to the relays.
Security Notes
WebRelay-10 Plus™ does not employ a general purpose computer operating system and does not have features,
such as telnet, FTP, SSH, nor uncontrolled open ports. This means it is unlikely for someone to ‘break in’ to
WebRelay-10 Plus™ and access other devices on your local network. The simplicity of WebRelay-10 Plus™
makes it a inherently secure device. Nevertheless, as with any device installed on a network, appropriate security
precautions should be observed.
If WebRelay-10 Plus™ is installed on the Internet, it is recommended that passwords be enabled for the Control
Page. Passwords should be at least 8 characters in length and use a combination of upper and lower case letters
and numbers. For additional security, a rewall may be used to limit access to selected IP addresses. Another
option may be to set up a Virtual Private Network (VPN) between the network where WebRelay-10 Plus™ resides
and the client machine (web browser, another, ControlByWeb™ product, etc.).
Final Installation Notes
This ControlByWeb™ product supports connection to 10 Mbps and 100 Mbps networks. Although 100Mbps
networks are faster, the amount of data transferred to and from this device is very minimal and little, if any,
performance increase will be gained by setting it to 100 Mbps. There are advantages, however, to operate this
device at 10 Mbps. At 10 Mbps, less power is required, the unit runs cooler, and the lifetime of the product will be
extended.
Any changes to the Ethernet settings will require a removing and re-applying power to WebRelay-10 Plus™.
