XYCOM XVME-260 Channel temperature module

For a more secure installation, the floor mounted units can be bolted to the floor. Four anchoring holes are provided for this purpose. The term “more secure” does not imply seismic. The charger/rectifier is not meant for seismic installations. For such installations, an appropriately designed charger/rectifier must be purchased. If you are to install a charger/rectifier that was kept in the cold environment, let the charger/rectifier warm up for 24 hours, to avoid damaging the components and/or condensation on the live components. If the charger/rectifier is to operate in the temperature range above the specified upper limit, the output has to be de-rated by 0.83% / o F from 122o F to 140o F (1.5% / o C from 50o C to 60o C. Also, if the charger/rectifier is to be installed above 3300ft (1000m) of the sea level, its output has to be de-rated by 7% per 3300ft (1000m).

VENTILATION AND COOLING 

The rectifier/charger/rectifier is rated for the temperature range from 32°F (0°C) to 122°F (+50°C). To calculate the required air displacement (exchange) volume use the following equation: V = BTU x e (0.125 x H x Tk/To) / (Tr -Tk) V = air flow: [cubic meter/hour] BTU: Total dissipated heat Tr: Maximum allowed room temperature [°K] {i.e. 50°C = 323°K] Tk= Temperature of input cooling air To= 273 °K H = Altitude [km] Do not place the system in direct sunlight. In order to ensure the adequate ventilation and safe access, respect the following clearances: • 3 in. (10 cm) on each side and the top. • 3 feet (1 meter) in front of the unit or 1.5 charger/rectifier width, whichever is greater.

ELECTRICAL CONNECTION AND WIRING

 The AC and DC ratings are provided for each charger/rectifier on the nameplate. The nameplate is located on the front panel. The AC wire size ampacity should match the current specified on the nameplate or the current rating of the AC breaker or fuse(s), whichever is greater; unless otherwise specified by the local or national electrical code and/or standards. The DC wire size should be chosen based on two factors – the first is the output current rating of the charger/rectifier, and the second is less than 0.5V total voltage drop at the rated current between the battery and the charger/rectifier output terminals. Keep the DC leads together and as short as possible to get the lowest impedance.
