ASCO SURGE PROTECTIVE DEVICE
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The ASCO Model 310 surge protective device is a high quality, high energy surge current diversion system
designed to protect sensitive equipment from damaging transient voltage surges resulting from load switching, lightning strikes and other sources. The Model 310 is a modular product designed to be easily installed in existing AC panelboards and control panels using standard DIN-rail mounting brackets.
The installer should perform the following steps to assure a quality installation. Please read all instructions before starting the installation of this product. These instructions do not replace national or local electrical codes.
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.
Environment — For use indoors, in an ambient temperature of -40°C to +85°C, with a relative humidity of 0% to 95% (non-condensing).
Mounting — Unit mounts to standard 35mm symmetrical Din rail (EN50022/DIN46277-3). Connections — Unit should be connected in parallel with the power source (see Diagram 1 on page 3).
The length of wire is critical to the performance of this device; therefore the connection wires should be as short as possible. If installation cannot accommodate short wires the Kelvin method of wiring should be used to improve performance of the SPD (see Diagram 2 on page 3). Wire Sizing/Routing — Wire connection terminals accept wire with the cross sectional area of 6 ­35mm2. To reduce the wire impedance to surge currents all conducts should be twisted together and routed in the same conduit raceway. All sharp bends in conductors should be avoided. Over Current Protection — External over-current protection is required. A 50A rated fuse or a 32A circuit breaker is to precede the incoming terminals of the SPD. Remote Status Connections — Unit is provided with remote status contacts located on the base of the device. The contacts may be wired using either the normally open “NO” or normally closed positions depending whether there is a need to monitor if the unit is in ok or failed status. After all modules are installed and operating normally the contacts are open. If modules are removed or failed the contacts are closed (see Diagram 3 on page 3).
OPERATION
CAUTION – For proper and safe operation, neutral and ground MUST be reliably connected. Failure to operate this unit from a
solidly grounded power source of the proper configuration will reduce or impede operation, and may result in unit failure.
ATTENTION - Pour un fonctionnement correct et sûr, le neutre et la mise à la terre doit être connectés de manière fiable. Défaut de faire fonctionner cet appareil à partir d'une source d'alimentation solidement mise à la terre va réduire ou même empêcher le fonctionnement correct et peut entraîner une défaillance de l'unité.
This product is designed for years of trouble-free operation and requires little or no operator intervention after installation. If a green indicator appears in the window of the module, the device is operating normally. If the red indicator appears, the module has reduced protection and must be replaced. Prior to replacing module assure the voltage supplied to the unit is correct and that the modules are not loose in the base causing a false failure. Replacement modules are available for this device; see MODEL NUMBER CONFIGURATION on next page.
TROUBLESHOOTING
If any diagnostic indicators indicate a problem, 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 607-721-8840.
