The cabinet is dust and water protected but is not suitable for outdoor installations where an integrity rating of at least IP65 or 66 should be sought. End users are responsible for the integrity of the cabinet once it has left our premises. If unsure please contact us.
The Zellabox cabinet has an integral cable management system built into the unit. Network cabling can be terminated at the cabinet at removable gland plates on the base of the cabinet (front or rear) or alternatively at a removable gland plate on the top of the cabinet. At each gland plate entry point, an internal compressed sponge panel is provided to assist with dust proofing of the cabinet. It is the responsibility of the cable installers to ensure that cabinet integrity is maintained when terminating cables into the cabinet. Special cable transit units can be supplied on request. These units allow the flexibility of adding cabling while maintaining integrity.
The unit should ideally be placed close to an external wall where the cooling system outdoor unit can be mounted. All installations will require a specialist installation of standard refrigeration pipe work, condensate drain, electrical interconnection and commissioning.
In most instances where the unit has been installed according to the prescribed guidelines, the customer may relocate the unit himself or seek a qualified agency to do so. Improper installations would render warranties null and void.
Generally the UPS systems are maintenance free but battery packs have a limited lifetime and should be tested regularly for efficiency.
The duration of UPS battery times should be selected dependent upon the critical nature of the equipment being protected as well as the source of the primary power. If power is being supplied to the cabinet via normal mains then longer battery times may be sought to ensure critical equipment maintains maximum uptime. It must be remembered that unless the Zellabox system is fed from an emergency generator power supply, the cooling system will not function in the event of a mains power failure. Generator supplies or emergency back-up fans are recommended on all installations. In the case where mains fail and there is no emergency supply, then the system will initiate alarm responses to designated addresses or mobile phones. It is recommended that cabinet doors be opened to assist with cooling. Equipment can also be interfaced with the UPS system to initiate emergency power down procedures.
All installations will require a specialist installation of standard refrigeration pipe work, condensate drain, electrical interconnection and commissioning. The unit should be mounted on the supplied mounting brackets and positioned according to the installation instructions supplied. The unit should be positioned in a well-ventilated area (preferably out of direct sunlight but this is not essential). Where it is unavoidable to place the outdoor unit in a location that exceeds the standard hose length then a professional retro-fit installation would be required. Your local Zellabox representative would be able to assist you in this regard. The unit should be positioned, as closely as possible, at the same elevation as the indoor unit or, at least, within the restrictions outlined in the manufacturer’s guidelines. If it is unavoidable that the unit has to be placed within a building, this should, as far as possible, comply with the above described conditions; well ventilated etc.
All cabinets come fitted standard with a condensate pump which will disperse condensate water to a maximum of 15m (up to an 8m lift), alarmed only where monitored. Given the relatively small volume of the conditioned space and the proposed recommendation to have the environment controlled as well as dust-free, there would be little or no condensate water generated under such conditions. Even in high humidity applications, the relative amount of condensate within a fixed, sealed volume would remain constant and negligible. A drain outlet is provided that can be run to an external wall should this be deemed necessary. An option is available; however, for a condensate pump to be installed in the base of the unit should users desire to do so. In most applications this is not necessary. A further precautionary measure is the standard deployment of a moisture sensor in the drain pan of the indoor unit which will initiate an alarm condition should the level of liquid rise abnormally for any reason.
The cabinet doors are intended to be kept closed for most of the unit’s lifetime. This would reduce both the incidence of dust accumulating on the evaporator coil of the indoor unit, as well as preventing humid air from being drawn into the enclosure thereby increasing condensate water generation. External conditions affecting outdoor units would vary from site to site, however. The requirement of keeping the cabinet doors closed would not impact, in any way, the normal access to the user equipment.
Under normal environmental conditions in most towns and cities thus far encountered, the cooling systems require minimal maintenance every three to four months. This is to ensure that the outdoor unit coil fins have not been clogged with dust and that the system gas charges are within acceptable norms. In the event of a system failure, the unit can be replaced within the constraints of the SLA in place for that particular customer. Response times and replacement deliveries would also be determined by the specific SLA in place with that particular customer.
