7400 Series UPS User Manual Single Module and One plus One Systems Chapter 1 - General Description Introduction 12 Pulse Rectifier The UPS basically operates as an a.c.-d.c.-a.c. converter (see figure 1-1). The first conversion stage (from a.c. to d.c.) uses a 3 phase 12 pulse (2 x 6 pulse), fully-controlled SCR bridge rectifier system to convert the incoming mains supply into a regulated d.c. busbar (432V d.c. for a 380V a.c. input; 446V d.c. for a 400V a.c. input or 459V d.c. for a 415V a.c. input).

Chapter 1- General Description One Plus One System 7400 Series UPS User Manual Single Module and One plus One Systems 6310018a.02.doc 1.3 One Plus One System The one-plus-one system comprises two standard 7400 series UPS modules which are modified to allow their outputs to be connected in parallel. These can then be used in a "redundant" or "non-redundant" configuration as explained below. 1.3.1 Redundant vs Non-Redundant configuration 1.3.
7400 Series UPS User Manual Single Module and One plus One Systems Chapter 1 - General Description One Plus One System 6310018a.02.doc Redundancy configuration: A link in the parallel control logic determines whether the one-plus-one system operates in a "redundant" or "non-redundant" configuration. If a non-redundant mode is selected the two static switch sections are effectively locked together in that both static switches are turned off or on by a single control signal.

7400 Series UPS User Manual Single Module and One plus One Systems Chapter 2 - Operating Instructions Introduction 6310018a.02.doc 2. 2.1 Chapter 2 - Operating Instructions Introduction The UPS can be considered to be in one of three operating conditions: • • Shutdown - All power isolators and circuit breakers open - no load power. On Maintenance Bypass - UPS shut down but the load connected to the unprotected mains via the Maintenance Bypass Supply line.
When the first module is stopped its static bypass is inhibited because the load will be fully maintained by the inverter of the second module.
Chapter 2 - Operating Instructions One plus One 7400 Series UPS User Manual Single Module and One plus One Systems 6310018a.02.doc When shutting down the second module, the static bypass lines of both modules will be turned on as soon as its inverter is stopped. That is, both modules will provide load power through their paralleled bypass lines. 2.2.
Chapter 2 - Operating Instructions One plus One 7400 Series UPS User Manual Single Module and One plus One Systems 6310018a.02.doc How to turn on the system from a maintenance power-down condition This procedure should be followed to start the UPS from a MAINTENANCE power-down condition - i.e. where the load is being initially powered through the internal maintenance bypass supply. Note: For a one plus one system, complete these actions on one module at a time. Step 1. 2. 3. 4. 5. 6. 7.
7400 Series UPS User Manual Single Module and One plus One Systems Chapter 2 - Operating Instructions One plus One 6310018a.02.doc How to turn off the system but continue to provide load power through the maintenance bypass This procedure should be followed if the UPS is to be powered-down while continuing to supply the load through the maintenance bypass line. Note that during this procedure the load will be unprotected against mains supply disturbances once the inverter(s) has been switched off.
Chapter 2 - Operating Instructions One plus One 7400 Series UPS User Manual Single Module and One plus One Systems 6310018a.02.doc How to totally power-down the system This procedure should be followed only if the UPS AND LOAD are to be completely powered down. Step 1. 2. 3.
