Battery Installation

2.3.2Temperature Considerations

Valve-regulated, lead acid battery cells are sensitive to ambient temperature and should be operated between 15°C and 25°C (59-77°F). Battery capacity is increased by 1% for every 1°C (2°F) increase in temperature up to 25°C (77°F). Battery life is reduced at temperatures above 25°C (77°F).

When batteries are mounted in the same room as the UPS unit, it is the battery that dictates the designed maximum ambient temperature, not the UPS. — i.e. in the case of valve-regulated cells, the ambient room temperature should be kept between 15°C and 25°C (59-77°F), and not between 0°C and 40°C (32-104°F) (which is the specified main equipment operating temperature range). Tempera- ture deviations are permissible for short periods, provided the average temperature does not exceed 25°C (77°F).

2.3.3Dimensions

The external dimensions are shown in Table 8. These are the same height and depth as the UPS module and provide a matching appearance when bolted together. All cabinets are fitted with doors, which must be fully opened in order to fit or remove the batteries. The door swing must therefore be taken into consideration when planning the positioning of the cabinets.

2.3.4Weight

The unladen weight is shown below in Table 8. When designing the battery installation the weight of the batteries and cables must be added to the unladen weight. This is particularly important when placing the NX on a raised floor.

2.3.5Circuit Breaker Features

In 30 to 40kVA models fitted with internal battery and in all models fitted with a Battery Start kit, the UPS is fitted with an internal contactor for automatic connection and disconnection of the batter- ies. External battery banks connected to such models generally are protected by a standard battery circuit breaker (with status contacts and without undervoltage trip coil). Refer to 2.5 - Battery Con- trol for details.

When no internal contactor for automatic disconnection is installed in the UPS module, the external battery disconnection is performed by fitting a Circuit Breaker Controller Board and an undervoltage coil to the battery circuit breaker.

The circuit breaker can then be manually closed once the DC busbar is above the ‘low battery; trip voltage. Once closed, the circuit breaker can be opened manually at any time and is tripped automat- ically by the UPS module following certain fault occurrences, an emergency power off command or if low/high DC busbar voltage is detected. Refer to 2.5 - Battery Control for details.
