Section 2: Installation and Setup

Installation consists of mounting WebRelay-10, connecting it to an Ethernet network, providing power,
configuring 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 qualified personnel.
• This unit must not be installed in unprotected outdoor locations.
• The WebRelay-10 must installed inside an NRTL certified industrial control panel or similar
NRTL certified fire/electrical enclosure.
• If the WebRelay-10 is used in a manner not specified 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 significant loss or
property damage.
•
The relay tab terminals are 1/4" x .032". Use UL listed quick-connect connectors suitable for field
connections. Use a suitable crimping tool as specified by the connector manufacturer. Use wire
rated for 75ºC (min) for connections to the relays.
Security Notes
WebRelay-10 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 and access other devices on your local network. The simplicity of WebRelay-
10 makes it a inherently secure device. Nevertheless, as with any device installed on a network,
appropriate security precautions should be observed.
If WebRelay-10 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 firewall 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 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.
