OVERVIEW Description The PRG Series 400® 400 Amp Disconnect is a safety device containing a three-phase, 400 Amp circuit breaker serving as a Main Breaker for high current AC power distribution systems. A Disconnect unit is required when 5-wire, 4/0 AWG feeder cables greater than 10 feet in length are connected from a house service greater than 400 Amps per phase to a portable power distribution system.
Controls and Indicators The S400 Disconnect contains the following connections and LED indicators. Voltmeters - measures phase voltages to ensure supply voltage is correct. Voltage input to the Cam-Loks is measured before the breakers and will show the input voltage even when the Main Breaker is off. INPUT VOLTAGES 600A MAX Voltmeter Rocker Switch - allows connection of the meters between the three phases (Ø-Ø) or between each phase and neutral (Ø-N).

INSTALLATION Installing S400 Disconnect The S400 Disconnect is installed between the house service and a portable power distribution system, such as the PRG Series 400 Power and Data Distribution System. It may also be used to protect a dimmer installation. CAUTION: Before installing, refer to "Proper Use and Operation" on page 3. WARNING: Ensure house service main breaker and S400 Disconnect breaker are OFF before connecting mains power cables. Ground should always be connected first. To install: Step 1.
Step 5. Ensure that Main Breaker is switched OFF (Figure 4). Step 6. At INPUTS, connect input power cable Cam-Loks in the following order: 1) Ground, 2) Neutral 3) X Phase, 4) Y Phase, and 5) Z Phase.
Set the Inrush Current Limit: Some loads, such as incandescent lamps or electric motors, can draw a large surge of current through the Main Breaker when they are quickly energized with voltage. When the Inrush Current Limit of the Main Breaker is exceeded, the Breaker will trip within a half cycle of the AC line. It is important that the Inrush Current Limit be properly adjusted so that these normal, but large surges do not cause nuisance tripping of the Main Breaker.
Power Up Sequence Use the following procedure to power up unit: Step 1. At house service main breaker, turn power ON. Step 2. At rear of Disconnect, verify all phase indicators are lit (Figure 6).

MAINTENANCE Cleaning/Replacing Rack Air Filters The air filters, located in the interior rack assembly, will require periodic cleaning. The frequency will depend on the amount of use and/or exposure to dusty environments. Parts: 40.7155.0120.0 FILTER, FAN 120MM, MESH ALUMINUM Tools: #2 slotted screwdriver WARNING: Remove power from rack before performing any maintenance procedures. To clean/replace rack air filters: Step 1. Disconnect ALL power from rack. Step 2.
