ADCP-80-524 • Issue 1 • November 2001 INTRODUCTION ® This manual describes the PowerWorx Type 70 Series Power Distribution Panels and provides installation, test, operation, and maintenance procedures. Two types of PowerWorx Type 70 power distribution fuse panels are available: the traditional power distribution fuse panel and the uninterrupted power distribution fuse panel. Within this manual, the fuse panels are referred to as the “traditional fuse panel” and “uninterrupted fuse panel.
ADCP-80-524 • Issue 1 • November 2001 General Safety Precautions - Caution: The fuse panel uses electrical voltage and amperage levels which, per GR-1089, may be considered an electrical hazard. Care should be exercised to assure that only qualified personnel are allowed to install, operate, maintain, or otherwise come in contact with this equipment when the panel is energized. Only insulated tools should be used on energized elements of the panel.
ADCP-80-524 • Issue 1 • November 2001 Standard Equipment Type 70 series fuse panels have two power buses (feeds). The capacity of each bus is eight fuse positions with up to 10 Amps per fuse position (within the maximum bus capacity). Each bus has Power-On and Alarm indicators on the front of the chassis and input, output, ground, and alarm contact connections on the rear of the chassis. The current capacity of each bus of the traditional power fuse panel is 65 Amps maximum (130 Amps per panel).

ADCP-80-524 • Issue 1 • November 2001 1.1 Power Buses Each fuse panel has two separate power buses (feeds). Each bus distributes the input power to the output power circuits. In each bus circuit, current flows from the input power bus, through the fuse, to the output power circuit. A typical fuse panel block diagram is shown in Figure 7. The current capacity of each bus of the traditional power fuse panel is 65 Amps maximum.

The wire is inserted into the connector and the set screw is tightened down, compressing the wire. The set screw barrel connectors can accept up to #6 AWG copper wire. 1.5 Output Voltage The output voltage will be the same voltage as the applied input voltage when the fuse does not fail. 1.
ADCP-80-524 • Issue 1 • November 2001 1.9 Power-On Indicator A visual power-on indicator (green LED) for each power bus is mounted on the front panel of the fuse panel. A lighted LED indicates that power is applied to the bus input connectors. An unlighted LED indicates that power is not applied to the bus input connectors. The LED can easily be replaced in the field if it fails. 1.10 Fuse Alarm Indicator A visual fuse alarm indicator (red LED) is provided on the front panel for each power bus.
ADCP-80-524 • Issue 1 • November 2001 1.14 Fused Equipment Designation Card and Holder Two fuse designation cards, shown in Figure 8, and a card holder with a clear plastic cover are provided with the fuse panel. The card holder may be attached to the fuse panel, the fuse panel mounting brackets, to the rack, or a location close to the fuse panel. One of the cards may be filled out with circuit information for each of the circuits and inserted in the card holder.
ADCP-80-524 • Issue 1 • November 2001 1.17 Cooling Vent openings are provided in the top and bottom of the fuse panel. The vent openings allow convection cooling of all components without the use of fans or blowers. 1.18 Protective Cover A smoked plastic protective cover is mounted over the input power connectors, the output power connectors, the chassis ground terminals, and the external alarm contact connections.

ADCP-80-524 • Issue 1 • November 2001 4.6 General Wiring Recommendations Route and connect ground, power, and alarm cables to the panel connectors according to local practice and the specified procedures. The connections to the fuse panel are shown in Figure 18. After routing the cables, tie them to the cable management bar (optional accessory). Replace the protective cover on the fuse panel after all the wiring connections are made and all tests are completed.
ADCP-80-524 • Issue 1 • November 2001 4.7 Chassis Ground Connection Mounting the fuse panel on a metal equipment rack using the metal mounting brackets provided with the fuse panel provides a sufficient return path to meet equipment grounding requirements. However, a separate grounding conductor is often required by local practice or local inspectors.
ADCP-80-524 • Issue 1 • November 2001 4.8 Output Power Connectors Note: Before connecting the output or input power wires, measure the resistance of each bus input connector as specified in Subsection 5.2, Resistance Test. Connect the output BATT and RTN terminals for each fuse circuit on each set of terminal strips as follows (see Figure 20): • Screw-down barrier terminal strip: Use #12 to #22 AWG wire.

Wire Wrap Alarm Contact Connection 4.10 Input Power Connectors Note: Before connecting the input or output power wires, measure the resistance at each bus input connector as specified in Subsection 5.2, Resistance Test.
ADCP-80-524 • Issue 1 • November 2001 • Set screw barrel connectors: Use only the barrel connectors on each connector assembly that are closest to the outside of the fuse panel. Use up to #6 AWG copper wire with insulation stripped back. Note: Do not loosen the set screws in the two barrel connectors that are closest to the center of the panel. Accessing these connectors may render the warranty void.
ADCP-80-524 • Issue 1 • November 2001 4.13 Voltage Designation Label Write the voltage used in the fuse panel on the voltage designation label (see Figure 9) and attach the label to the back of the panel. 5 TESTING Caution: This equipment employs electrical voltage and amperage levels which may be considered an electrical hazard.
ADCP-80-524 • Issue 1 • November 2001 5.5 Connection Polarity Test To verify that the input power wires are connected to the correct terminals, measure the voltage between the input return connector (RTN) and the chassis ground using a multi meter. The voltage should be less than 2.0 Vdc. If the voltage is more than 2.0 Vdc, reverse the input power wires and measure the voltage between the input return connector (RTN) and the chassis ground again to determine that the voltage is less than 2.0 Vdc. 5.
ADCP-80-524 • Issue 1 • November 2001 7.2 Cleaning If excessive dirt is found during the inspection, brush or wipe dust and dirt from the fuse panel with a soft bristle brush or soft cloth. Care should be taken not to damage the fuses or any wiring. 7.3 Adjustments No adjustments in the field are indicated or required. If a circuit is not operating properly, contact ADC Customer Assistance (see Section 8, Customer Information and Assistance). 7.
