Single Module UPS Installation

1.3Location

1.3.1UPS Room

The UPS and its internal battery is intended for indoor installation and should be located in an envi- ronment with clean air and with adequate ventilation to keep the ambient temperature within the specified operating range (see Table 33).

All models in the Liebert NX UPS range are air-cooled with the aid of internal fans. Cold air enters through ventilation grilles at the front of the cabinet for NXa 30-120kVA and through ventilation grilles located at the front and bottom of the cabinet for NXa 140-200kVA. Hot air is released through grilles at the top. Do not cover the ventilation openings.

If necessary to avoid room temperature build-up, install a system of room extractor fans. Optional air filters are available if the UPS is to operate in a dusty environment.

The UPS heat dissipation detailed in Table 34 can be used as a guide for air conditioning sizing, depending on the selected mode of operation:

Normal Mode (VFI SS 111 Double Conversion UPS)

ECO Mode (VFD SS 311 Stand By UPS)

If in doubt use Normal Mode figures.

NOTE

The UPS is suitable for mounting on concrete or other non-combustible surface only.

1.3.2External Battery Room

Batteries should be mounted in an environment where the temperature is consistent and even over the whole battery. Temperature is a major factor in determining the battery life and capacity. Typical battery manufacturer performance data are quoted for an operating temperature between 20 and 25°C (68 and 77°F). Operating above this range will reduce the battery life while operation below this range will reduce the battery capacity. In a normal installation the battery temperature is main- tained between 15°C and 25°C (59 and 77°F). Keep batteries away from main heat sources or main air inlets etc.

Where the batteries are located externally to the main UPS cabinet, a battery protection device

(e.g., fuses or circuit breakers) must be mounted as close as possible to the batteries themselves, and connected using the most direct route possible.

1.3.3Storage

Should the equipment not be installed immediately, it must be stored in a room for protection against excessive humidity and or heat sources (see Table 33).

! CAUTION

An unused battery must be recharged periodically per battery manufacturer recommendation. Temporarily connecting the UPS to a suitable AC supply mains and activating it for the time required for recharging the batteries can achieve this.
