Introduction
CONNECTING YOUR UNDER-MONITOR
SURGE SUPPRESSOR
Connection to AC Power Line (all models)
The Under-Monitor Surge Suppressor power cord should only be connected to a standard
3-wire grounded 120-Volt AC, 60-Hz outlet.
Connection To Telephone Line (PLUS models only)
Under-Monitor PLUS models have two female RJ-style phone jacks that accept connection
of a wide range of equipment with male RJ-style plugs. PLUS models provide 2-wire/single
telephone line protection. PLUS models MUST always be the FIRST item connected in line
from the telephone jack. PLUS models MUST always be plugged into a 3-wire grounded
outlet for the telephone protection to work. Connect the phone cord from the wall jack
directly to the PLUS jack labelled "IN" (or "LINE"). Connect the phone cord from the device
to be protected directly to the PLUS jack labelled "OUT" (or "EQUIP"). The connected
equipment is now protected against spikes, surges and line noise on the telephone line.
CAUTION!
DO NOT connect to an ungrounded AC outlet. DO NOT connect to 2-wire extension
cords or adapters. Lack of a proper ground connection will eliminate common-mode
protection and cause small leakage potential on the case. However, you can plug 2-
wire devices into any of the surge suppressor's outlets.
