4.3 Protection Strategies
This UPS provides high performance power line protection to the loads. There are, however, other
potential entry points for damaging surges in information systems. These include serial ports (RS-
232, RS-422, RS-485, etc.), parallel ports, telephone lines, and LAN connections. These other entry
points must be considered in developing a comprehensive protection strategy for your system.
Contact your dealer or call the number in the front of this manual for information on related prod-
ucts designed to accomplish total system protection.
Sensitive information systems can be further safeguarded by following these guidelines:
n Verify that all electrical outlets are properly grounded. See section 4.9.
n Connect computer leads to a different electrical service branch than heavy motor loads like air
conditioners, copiers, refrigerators, and heavy industrial machinery.
n Plug all power protection and computer equipment into outlets connected to the same service
branch (controlled by the same fuse or circuit breaker) where possible.
4.4 Connect Computer Interface (Optional)
Power management software and interface kits can be used with this UPS. Use only kits supplied
or approved by the manufacturer. If used, connect the interface cable to the 9-pin computer inter-
face port on the back panel of the UPS. Secure the connector’s screws to complete the connection.
Note:
Computer interface connection is optional. The UPS works properly without a computer in-
terface connection.
4.5 Connect Telephone/Network Surge Suppression (Optional)
Connect a single line telephone or a 10Base-T network cable into the telephone/network surge
protection sockets on the back of the UPS. The RJ-45/RJ-11 modular combination sockets accept
all standard single line telephone and 10Base-T connections. This connection will require another
length of telephone cable (supplied) or network cabling (not supplied) to complete the connec-
tion. Note: This connection is optional. It is not needed to use the UPS.
