Electrical Connections

Usage:

The system should be installed per the National Electrical Code (NEC) and the local codes.

Input/Output Cabinet

The Input/Output cabinet receives following items for the system: the input cables for three-phase AC power, output cables for three-phase AC power, the ground cables and the neutral cables. Neutral cables are used only in systems that have four wires for the input power. The cabinet can accommodate the entry of the cable from the top of the cabinet or from the bottom of the cabinet.

There are six galvanized steel panels that are on the Input/Output Cabinet for the entry of the conduit. The panels are made of 12 gauge metal. The panels are removable. Three panels are located on top of the cabinet and three panels are located on the bottom of the cabinet. Each of the access plates that are located on the bottom of the Input/Output Cabinet can have a total of six holes with a diameter of 114.30 mm (4.50 inch). The panels that are located on the top of the cabinet are distributed in the following way: one panel for input one of the MMU, one panel for the bypass input of the MMU and one panel for the system output of the MMU. The panels that are located on the bottom of the cabinet are distributed in the following way: one panel for input one of the MMU, one panel for the bypass input of the MMU and one panel for the system output of the MMU. Holes must be punched in the field for the entry of the cable in order to accommodate the configuration of the system.

The Three-Phase AC Input Cables and the Three-Phase AC Output Cables are connected to a plated copper bus bar. The bus bar is drilled and tapped for 13 mm (0.5 inch) bolts. The holes are spaced for the following components: long barrel lugs with one hole and long barrel lugs with two holes.

The ground cable is connected to a plated copper bus bar. The bus bar is drilled for 13 mm (0.5 inch) hardware. The holes are spaced for NEMA lugs with one hole.

The torque for the wire connections is 56.5 N·m (42 lb ft).

Note: Only NEMA lugs should be used.

Note: The lugs and the cable are not supplied.

Route the ground cables into the system cabinet. Use the output holes that are punched in the system cabinet.

Refer to NEC Article 210-19 and refer to NEC Table 310-16 for the correct size of the cables.

Refer to NEC Article 250-95 for the correct size of the ground.

Refer to NEC Article 310-15 for the correct size of the neutral.

Note: A service disconnect device must be installed. This device must be rated properly for the output power.

Input/Output Cabinet to AC Power Connections in the System Cabinet

Show/hide table

Underwriters Laboratories Inc. requires that this system must be installed with an appropriately rated service disconnect device for the output power.

If required by local and/or national regulations, appropriately rated service disconnect devices must be provided for the input power and for the output power.

Overcurrent protection must be provided externally to the UPS. Overcurrent protection must comply with the national codes and the local codes.

Show/hide table

To reduce the risk of fire, connect only to a circuit provided with 2000 Amperes maximum branch circuit overcurrent protection in accordance with National Electrical Code, ANSI/NFPA 70.

The connections for the Input/Output cabinet to the System cabinet are made by using plated copper bus bars.

Note: The bus bar and the hardware are supplied.

UPS NET Connections

Initial Setup Procedure for UPS NET

Note: The main electrical connections that are between the System Cabinet and each MMU should be made by the contractor that is installing the system. The main electrical connections that are between the System Cabinet and each MMU must be made before performing the following procedures.

Place the key switch for the System Cabinet and the key switches for the MMU in BYPASS.

Remove the sheet metal panels and remove the panel for the System Input/Output board on each MMU and the System Cabinet. The System Input/Output board is located in the lower left side of the cabinet.

Primary Cable Connections for UPS NET

Note: "J8" is a single connector with two "RJ45" ports.

Connect a network cable from connector "J8A" on the System Input/Output board in the System Cabinet to connector "J8A" on the System Input/Output board in MMU 1.

Connect a network cable from connector "J8B" on the System Input/Output board in MMU 1 to connector "J8A" on the System Input/Output board in MMU 2.

Connect a network cable from connector "J8B" on the System Input/Output board in MMU 2 to connector "J8A" on the System Input/Output board in MMU 3.

Connect a network cable from connector "J8B" on the System Input/Output board in MMU 3 to connector "J8A" on the System Input/Output board in MMU 4.

Install a network cable terminator in the last MMU that is connected to the system. Verify the presence of a network cable terminator in the connector "J8B" of the System Input/Output board in the System Cabinet.

Secondary Network Setup

Note: "J8" is a single connector with two" RJ45" ports.

Connect a cable (network) from the connector "J8A" on the System Input/Output Daughter board in the System Cabinet to the connector "J8A" on the System Input/Output Daughter board of MMU 1.

Connect a network cable from the connector "J8B" on the System Input/Output Daughter board of MMU 1 to the connector "J8A" on the System Input/Output Daughter board of MMU 2.

Connect a network cable from the connector "J8B" on the System Input/Output Daughter board of MMU 2 to the connector "J8A" on the System Input/Output Daughter board of MMU 3.

Connect a network cable from the connector "J8B" on the System Input/Output Daughter board of MMU 3 to the connector "J8A" on the System Input/Output Daughter board of MMU 4.

Install a network cable terminator in the last MMU that is connected to the system. Verify the presence of a network cable terminator in the connector "J8B" of the System Input/Output Daughter board in the System Cabinet.
