ASCO 200 SERIES
power line filters offer the original Active Tracking™ technology to guard against
commonly occurring, but very damaging, lower energy transients and offers excellent noise reduction.
The Model 277 & Model 275 combine rugged, high energy current diverters with the Active Tracking™
Filter to provide protection against the full spectrum of voltage transients and surges.
INSTALLATION
DANGER! ONLY QUALIFIED PERSONNEL SHOULD INSTALL OR SERVICE
THIS SYSTEM. ELECTRICAL SAFETY PRE-CAUTIONS MUST BE FOLLOWED
WHEN INSTALLING OR SERVICING THIS EQUIPMENT. TO PREVENT RISK OF ELECTRICAL SHOCK,
TURN OFF AND LOCK OUT ALL POWER SOURCES TO THE UNIT BEFORE MAKING ELECTRICAL
CONNECTIONS OR SERVICING.
DANGER! SEULEMENT LE PERSONNEL QUALIFIÉ DOIT INSTALLER OU MAINTENIR CE
SYSTÈME. DES PRÉCAUTIONS DE SÉCURITÉ EN ÉLECTRICITÉ DOIVENT ÊTRE SUIVIS LORS DE
L’INSTALLATION OU DE LA MAINTENANCE DE CET EQUIPEMENT. POUR EVITER TOUT RISQUE DE
CHOC ÉLECTRIQUE, DÉBRANCHEZ ET VEROUILLER TOUTES LES SOURCES D’ ALIMENTATION DE
CET EQUIPEMENT AVANT DE LE BRANCHER OU LE MAINTENIR.
Proper installation is required for maximum system performance. Read the following information to
assure a quality installation. These instructions do not replace national or local electrical codes.
Environment –
For use indoors, in an ambient temperature of -40°C to +50°C, with a relative humidity
0% to 95% (non-condensing).
Maximum Current Capability –
The total current draw for all loads that a model may continuously
handle is given in the MODEL NUMBER CONFIGURATION table found on the next page. Overloading the
unit can permanently damage the device.
Nominal Voltage –
The nominal operating voltage for each model is given in the MODEL NUMBER
CONFIGURATION table found on the next page. Failure to use the unit at its rated voltage can permanently
damage the unit or provide inadequate surge protection.
Supplemental Enclosures -
All units provided with exposed terminal blocks must be installed inside an
enclosure and located so as to prevent accidental contact with terminals during maintenance or servicing.
Summary Alarm Contacts (Model 277 only) –
Summary alarm Form C (1 N.O. and 1 N.C.) relay contacts
rated 125VAC, 5A max. are provided for remote indication of protection status. Connections may be made
to these terminals on the unit using 18 AWG conductors.
Grounding -
Input and output ground terminals (if provided) must be connected for proper operation.
This grounding is not only required for safety, but also for equipment performance. Incorrect grounding
can reduce or impede the operation of the unit.
Line Cord Units (Model 275 only) –
Plug unit into wall outlet and turn on power switch (if provided). For
best results, plug equipment to be protected directly into the unit (do not use extension cords or power
strips). Keep data cables as far away from power cords as possible.
OPERATION
These products are designed for years of trouble-free operation and require little or no operator
intervention after installation. Should the unit not appear to be functioning properly and/or the indicator
LED (if provided) is extinguished, check all connections, and assure the voltage is correct and that the
total current draw on the unit from all loads does not exceed the rated current. If the unit still is not
functioning properly, call ASCO Surge Protection at 800-237-4567.
TROUBLESHOOTING
If any of the diagnostic indicators indicates a problem (i.e. red LED ON, and/or green LED OUT), check all
connections and voltages to the unit. If all connections are reliable, and proper voltages are supplied to
the unit, call ASCO Surge Protection, Inc at 800-237-4567.
