Installation Recommendations

DANGER
hazard of electric shock, explosion, or arc flash Read and understand all safety messages before performing installation, start up, and maintenance of the equipment. Under no circumstances should the characteristics of the apparatus itself be altered or modified. Disconnect power to the cooling unit before opening the enclosure, and ensure that the enclosure is closed before reconnecting power. Follow all national and local electrical codes applicable in the country of use. Comply with all instructions and prohibitions set forth in this manual. Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising from the use of this material. The supply voltage must not exceed the value on the product nameplate. Failure to follow these instructions will result in death or serious injury.

DANGER

hazard of electric shock, explosion, or arc flash

Read and understand all safety messages before performing installation, start up, and maintenance of the equipment.
Under no circumstances should the characteristics of the apparatus itself be altered or modified.
Disconnect power to the cooling unit before opening the enclosure, and ensure that the enclosure is closed before reconnecting power.
Follow all national and local electrical codes applicable in the country of use.
Comply with all instructions and prohibitions set forth in this manual.
Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel.
No responsibility is assumed by Schneider Electric for any consequences arising from the use of this material.
The supply voltage must not exceed the value on the product nameplate.

Failure to follow these instructions will result in death or serious injury.

NOTICE
COMPRESSOR AND SEAL DAMAGE Improper sealing of the enclosure (minimum IP55 for side-mounted cooling units or IP54 for roof-mounted cooling units) may result in excessive condensation. Use the air inlet filters if the cooling unit is exposed to airborne contaminants and/or aggressive chemicals. Allow sufficient external and internal clearance for air flow into, within, and out of the cooling unit. Failure to follow these instructions can result in equipment damage.

NOTICE

COMPRESSOR AND SEAL DAMAGE

Improper sealing of the enclosure (minimum IP55 for side-mounted cooling units or IP54 for roof-mounted cooling units) may result in excessive condensation.
Use the air inlet filters if the cooling unit is exposed to airborne contaminants and/or aggressive chemicals.
Allow sufficient external and internal clearance for air flow into, within, and out of the cooling unit.

Failure to follow these instructions can result in equipment damage.

CAUTION
hazard of enclosure collapse Check that the side, the door or the roof of the enclosure can support the weight of the cooling unit. Install supports if necessary. Failure to follow these instructions can result in injury or equipment damage.

Check that the external environment does not show any concentration of solid contaminants and/or excessive amounts of aggressive chemicals, according to IEC 62208. If there is a concentration of solid contaminants and/or excessive amounts of aggressive chemicals, use the air inlet protection filters.

Check that the air flow inlet and outlet are not blocked by walls or objects that are too close.

Maintain at least 1 m (3.26 ft) between the cooling unit and walls or adjacent enclosures.
Maintain at least 1.5 m (4.92 ft) between the cooling unit and ceiling.
Maintain at least 100 mm (3.93 in) between the cooling unit and any device mounted on the inside of the enclosure.

Before drilling or cutting the enclosure, check that the fasteners and coupling do not impede or interfere with the switch gear located on the enclosure.
Install the cooling unit with the air intake from the enclosure located at the highest possible point.
For indoor cooling units, check that the ambient temperature in the area of the enclosure installation is not above 55 °C (131 ºF) or below 5 ºC (41 ºF).

For outdoor cooling units, check that the ambient temperature in the area of the enclosure installation is not above 55 °C (131 ºF) or below -20 °C (-4 °F). In any case, respect the ambient temperature specified in the technical data.

For indoor and the outdoor cooling units, check that the relative humidity does not exceed +95 %.
Place the cooling unit away from sources of heat and hot airflows.
Check that the sealing of the enclosure is IP55 or higher for side-mounted cooling units and IP54 or higher for roof-mounted cooling units to avoid excessive condensation.
Seal properly the cable holes and other openings in the enclosure, especially the floor and cable entrances.
Install the cooling unit in the correct position. The maximum deviation from the perpendicular is 2°.
Any modifications to the cooling unit that are not listed in this guide or in other Schneider Electric documentation are prohibited.
