7 – Operating Modes

This section provides a basic description of the UPS system’s operating modes. The one-line diagrams used are schematic representations. For more information about switching between operating modes, refer to Section 8 – Start-Up, Shutdown and Bypass.

7-1 Online (Normal) Mode (Single UPS—SUS)

In online (normal) mode, the UPS system’s rectifier converts incoming AC utility power to DC power that charges the batteries and supplies the inverter. The inverter transforms the DC power to precision-regulated, pure sine wave AC power that supports the operation of connected equipment. This dual conversion technology isolates connected equipment from all power problems and ensures that connected equipment receives ideal power at all times.

7-2 Battery Backup Mode (Single UPS—SUS)

When a power outage or other extreme power event occurs, the UPS system automatically switches from normal mode to battery backup mode. The UPS system’s batteries (internal and/or external) provide emergency DC power to the inverter. The inverter transforms the DC power to precision-regulated, pure sine wave AC power that supports the operation of connected equipment.

7-3 Auto Bypass Mode (Single UPS—SUS)

If the inverter malfunctions due to excessive temperature, overload, output short circuit, abnormal voltage or battery problems, the inverter will shut down. If the UPS system detects a bypass (reserve) power source that conforms to normal parameters, then the UPS system automatically switches to auto bypass mode to continue supplying power to connected equipment. When all problems are eliminated, the UPS system switches back to online (normal) mode automatically.

7-4 Manual Bypass Mode (Single UPS—SUS)

If UPS system maintenance or repair is required, you can bypass the UPS system and enable bypass (reserve) power manually. After confirming that the bypass source is present (input AC available and Q3 open), transfer to manual bypass mode by first pressing the off button to stop the inverter. This transfers the UPS to static internal bypass. Next, switch the UPS system into manual bypass mode. (See Section 8-5 for complete manual bypass procedure.) The one-line diagram illustrates the system status and flow of power after the manual bypass procedure has been completed. This allows service technicians to perform maintenance or repair procedures without interrupting the flow of AC power to connected equipment. Warning: After switching to manual

bypass mode to perform selected maintenance or repair procedures, the UPS may require complete shutdown to affect those repairs. Use of an external 3-breaker maintenance bypass panel can facilitate this and still maintain AC power to the connected equipment.

7 – Operating Modes (continued)

7-5 Online (Normal) Mode (Parallel UPS—MUS)

Parallel configuration provides UPS system redundancy or increased total capacity. Under parallel configuration, the

total load is shared by 2 to 4 UPS systems. If one of the UPS systems malfunctions, the total connected equipment load is supported by the remaining UPS systems. If the total load exceeds the capacity of the remaining UPS systems, the MUS

will switch all UPS units to auto bypass mode. The diagram illustrates the on-line mode for a 2x MUS.

7-6 Battery Backup Mode (Parallel UPS—MUS)

Similar to battery backup mode for a single UPS system (Section 7-2), except the total connected equipment load is

shared by the parallel UPS systems (2 to 4). The diagram illustrates the battery backup mode for a

2x MUS.

7-7 Auto Bypass Mode (Parallel UPS—MUS)

Similar to auto bypass mode for a single UPS system (Section 7-3), except with parallel UPS systems (2 to 4).

The diagram illustrates the auto bypass mode for a 2x MUS.

7 – Operating Modes (continued)

7-8 Manual Bypass Mode (Parallel UPS—MUS)

Similar to manual bypass mode for a single UPS system (Section 7-4), except with parallel UPS systems (2 to 4).

Note: All UPS systems must be switched into manual bypass mode.

The diagram illustrates the manual bypass mode for a 2x MUS.

7-9 External Maintenance Bypass Mode (Parallel UPS—MUS)

Utilizing the external parallel cabinet with system level maintenance bypass panel, the parallel UPS systems can be completely isolated for maintenance or repair procedures while the connected equipment remains powered.

Transfer to external maintenance bypass mode should only be accomplished once each individual UPS unit has been placed in auto or manual bypass first.

12-212-93-3141.indb 19 12/28/2012 11:17:29 AM

8 – Start-Up, Shutdown and Bypass

Warning: The UPS system’s output voltage and frequency are set at 220/380V, 50Hz by default. If you require output voltage of 230/400V or 240/415V, or a frequency of 60Hz, you must change the UPS system’s output voltage and/or frequency by accessing the output setup menu described in Section 10-5-2. You must place the UPS system in bypass mode before changing the output voltage. Do not connect your

equipment to the UPS system’s output until you have set the proper parameters.
