2.2.11. External signal interface terminal

The UPS Module is equipped with a series of input/output terminals for external

annunciation of alarms and for remote access of certain UPS functions.

A. Terminals OUT 1 to OUT 6 are user programmable, with the default settings:

a. OUT 1: Load on Bypass

b. OUT 2: Load on Inverter

c. OUT 3: Battery Operation

d. OUT 4: Rectifier Operation

e. OUT 5: Battery Low Voltage

f. OUT 6: Overload

B. Terminals IN 1 to IN 5 offer the following remote functions:

a. IN 1: Remote Start

b. IN 2: Remote Stop

c. IN 3: Battery Temperature Abnormal

d. IN 4: Input Power Demand

e. IN 5: Remote Emergency Power Off) (EPO)

2.2.12. (OPTION) DiamondSync

The UPS manufacture shall offer a Sync circuit which shall allows any two or more

different UPS modules to sync into a master Sync source. The circuit allows both UPS

modules to operate in to a common output transfer cabinet and allows the load continue to

operate without any degradation to the load.

2.2.13. (OPTION) Common Battery

The customer is to advise if each UPS module is to have its own dedicated smaller battery

bank or if one large battery bank is required to operate the entire load.

2.3. CLC COMPONENTS

For additional information to below, refer to the Mitsubishi Electric CLC Specification.

2.3.1. CLC Power Section

Bypass Load Sharing Reactors (ACL1, ACL2 up to ACL8 depending on system

UPS Module quantity)

For equal load sharing, a load sharing reactor shall be incorporated in each UPS

Module circuit to ensure bypass line impedance balance and that each bypass line

supports an equal share of the total load current during bypass operation. Each

UPS Module circuit reactor will be located in the CLC. Refer to previous section

UPS MMS Bypass operation.
