T1000 Series UPS 5.6-6kVA Installation and Operation Manual – 91074-005

12.5 Cold Start (On Batteries)

The following illustration shows power flow during Cold Start. When the UPS must be started, and utility

power is not available, the UPS can be Cold Started (the UPS’s batteries supply DC voltage to the UPS’s

main inverter circuit.) This circuit changes (inverts) the DC power into AC power. The AC power is available

at the output of the unit.

NOTE: The default frequency mode is set to auto-detect. In auto-detect mode the default output frequency

at turn-on and cold-start is 60 Hz.

This battery discharge process will continue until either:

• Utility power is restored and the UPS auto-transfers to online mode,

• The UPS’s battery voltage drops below the Battery Shutdown voltage (Vmin) and the UPS shuts

down power to the load and turns itself off. The nominal minimum voltage Vmin is given in Table

12-1.

NOTE: The Battery-shutdown Voltage is automatically adjusted by the UPS based on load

percentage in order to maximize battery life.

The battery backup time and discharge process is explained in Section 12.7 – 12.9.

12.6 Frequency Conversion Mode (CVCF)

The default Frequency mode is Auto-detect; the Output frequency will be the same as the Input frequency:

60 Hz in and 60 Hz out, or 50 Hz in and 50 Hz out. In Auto-detect the parameter

CVCF is set to DISABLED.

NOTE: Only

ENABLE parameter CVCF if the desired output frequency is different that the input frequency.

To set the UPS for frequency conversion:

1. Access the menu parameter Settings > Status Config & Ctl > EN CVCS and select ENABLED.

2. Access the menu parameter Settings > Status Config & Ctl > CVCF Frequency and select the

desired output frequency - either

50.0Hz or 60.0Hz.

NOTE: Ensure the load is disconnected before changing the CVCF parameter value.

3. Cycle power to the UPS to save the new parameter settings.

Cold Start in Frequency Conversion Mode

The output frequency will be the selected output frequency

CVCF Frequency.
