4x4 POWER DISTRIBUTION UNIT Operation Manual PB 4X4 (FRONT) SP 4X4 (FRONT) PS 4x4 (FRONT) BACK (ALL UNITS) INTRODUCTION We congratulate you on choosing an ART 4x4 Power Distribution Unit. You will find that they have been designed for easy use. The latest advances in power technology have been utilized in the design of these units. Please read all instructions carefully before operating. All 4X4 Models (Power Base, Smart Power and Power Station) Feature: Front-Mounted Circuit Breaker Reset Switch Surge & Spike Protection EMI & RFI Filtering Unique 4X Distribution on the Back- Four of the Eight Rear Switched Outputs are wider for Wall Wart Devices Total Power Capacity of 1800 watts Rugged All-Steel Chassis Occupies 1u Rack Space Smart Power (SP) adds: 2 Front Shock-Mounted Light Posts Backlit Linear Meter to Monitor Input Voltage Separate On/Off Light Switch Adjustable Dimmer Dial Power Station (PS) has all SP features, and adds: Backlit Ammeter to Monitor Load Current The 4x4 POWER DISTRIBUTION UNITs protect your delicate electronic equipment with a high voltage varistor (MOV) surge and transient suppressor. The fast-acting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels. OPERATION MAXIMUM LOAD The eight circuit breaker protected outlets are rated at 15 amps, which is equivalent to 1800 watts at 120 volts. If the total load on the 4x4 POWER DISTRIBUTION UNITs outlets (and rack lights on the SP & PS) exceed 15 amps, the circuit breaker will trip, cutting off power to your rack. If this happens, reduce the load by unplugging one or more units from the 4X4 POWER DISTRIBUTION UNIT. Then push the circuit breaker button in to reset it. LAMPS (SP & PS) The 4x4 POWER DISTRIBUTION UNITs lamps pull out easily and may be aimed to provide the best illumination for your equipment. Each lamp is supplied with a 7-watt night light bulb. Replacements are readily available at most hardware stores, or wherever household light bulbs are sold. Adjust the DIMMER control for the desired brightness. The lights do not turn off automatically when the tubes are pushed in, so be sure to switch the RACK LIGHTS switch to the OFF position before pushing in the tubes. CAUTION-BURN WARNING: The caps and light tubes become hot during normal operation. Avoid burning your fingers by allowing the cap to cool completely before unscrewing it. Do not push the tubes in while the caps are unscrewed. If you find that the heat from the tubes is excessive, reduce the setting of the Dimmer control, or substitute a 4-Watt bulb. BULB REPLACEMENT (SP & PS) Bulbs are easily replaced without removing the unit from the rack. Simply unscrew the cap on the end of each light tube, remove the old bulb and replace. POWER SWITCHES The 4x4 POWER DISTRIBUTION UNIT has a master POWER switch for the rear outlets as well as the lights (SP & PS). This switch glows when the unit is on. Warnings 1.
