*Maximum voltage and current on pins 1, 7, 8 and 9 are 60VDC and 10.0 mA

10.2Pin 4 - Remote Shutdown on Battery

1.This pin is functional only when the UPS is in battery mode. If the UPS is being powered by utility power, Pin 4 will ignore any signal on this pin.

2.Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes from the serial port using Liebert's contact closure cable. It cannot be used with just a contact closure unless the relay is used to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or greater is required to signal a shutdown. Signals for less than 1.5 seconds will be ignored. After Pin 4 receives a shutdown signal for 1.5 seconds, the command cannot be canceled.

3.A battery shutdown signal on Pin 4 will NOT cause an immediate Shutdown. A shutdown signal will start a 2-minute shutdown timer. The timer cannot be stopped. After 2 minutes, the UPS will shut down.

4.If utility power returns during the 2-minute timer countdown, the shutdown timer will continue until the end of 2 minutes and the UPS will turn OFF. The UPS must remain OFF for at least 10 seconds even if AC input power Returns before the UPS turns OFF. This serves to reset and restart the server.

Whether the UPS turns back ON when power is restored depends on the auto-restart setting: enabled or disabled.

If the auto-restart is disabled, the UPS will not restart after performing the 2-minute shutdown delay.

GXT2-6000RTL630 specifications

The Emerson GXT2-6000RTL630 is a high-performance uninterruptible power supply (UPS) designed to safeguard critical equipment in various applications, including data centers, telecom systems, and industrial processes. This model is part of the GXT2 series, which is renowned for its reliability and advanced features.

One of the standout characteristics of the GXT2-6000RTL630 is its robust power capacity of 6000 VA/6000 W. This makes it ideal for protecting sensitive electronic devices against power disturbances such as surges, spikes, and complete power outages. The UPS is designed to deliver clean, continuous power with a sine wave output, ensuring that all connected equipment operates optimally.

A key feature of the GXT2-6000RTL630 is its double-conversion online technology. This ensures that the UPS provides uninterrupted power supply through its inverter, converting incoming AC power to DC and then back to AC. This process isolates connected devices from power fluctuations and increases the overall reliability of the power supply. With a wide input voltage range, the UPS can adjust to varying power conditions while maintaining a stable output.

The GXT2-6000RTL630 is equipped with an intuitive LCD display. This user-friendly interface provides real-time information about the UPS status, including input/output voltage, load level, battery capacity, and alarms. This allows users to monitor the system easily and take proactive measures if necessary.

In terms of battery management, the GXT2-6000RTL630 features advanced battery charging technology. It includes a hot-swappable battery design, allowing users to replace batteries without shutting down the system. This capability reduces downtime and increases operational efficiency. Additionally, the UPS employs intelligent battery management to maximize battery life and ensure reliable operation.

Another notable feature is its network management capability. The GXT2-6000RTL630 can be connected to a network through an optional SNMP/HTTP card, enabling remote monitoring and management. This is particularly beneficial for larger installations and organizations that require centralized control over multiple units.

Furthermore, the UPS supports multiple configurations, allowing for flexibility in installation according to space and power requirements. It can be rack-mounted or placed in tower mode, making it suitable for various environments.

In summary, the Emerson GXT2-6000RTL630 is a sophisticated UPS that combines high capacity, advanced technology, and user-friendly features. Its double-conversion architecture, real-time monitoring, and intelligent battery management make it an excellent choice for anyone needing reliable power protection for critical applications.
