Features of installation and connection of the UPS
When a power outage helps the uninterruptible power supply, especially necessary for continuous production, in stores and other service areas. It will not be superfluous to purchase it in a private house or apartment, if they have sensitive to power outage devices associated with life support systems.
Factors to consider when choosing a UPS:
- total power of connected devices;
- type of network and its voltage;
- the duration of the planned use of the device (its capacity depends on it)
The cost depends on the complexity of the device, its power, size and capacity and increases in proportion to these characteristics. In the case of the proposed expansion of the network, you need to purchase a more powerful device. You can find a wide range of UPSs here.
How to install
Available as a small low-power UPS in the form of a plastic box that fits anywhere, and larger models.The power source consists of the unit itself, included in the outlet, and only then the rest of the equipment is connected to it. Great difficulty connecting will not make. The main thing that needs to be done is to correctly sum up the power and the period of operation of the device in the event of a current supply shutdown. The three-phase large-size bespereboynik is a cabinet that weighs hundreds of kg. Such devices are mounted in the floor, which should be designed for the impact of this load. Installing and connecting powerful UPS is much more difficult.
How to connect
It will be more reliable that three-phase bespereboyniki connected and installed by certified professionals. The equipment is expensive, so you should ask the installer to present a certificate allowing to perform these works. The main requirement for connecting an uninterruptible power supply is the presence of a bypass. This is the conductive line in the event of a UPS failure. Small-sized turn off, and the "cabinets" has a handle on the back panel for connecting the bypass manually. It is possible to install an automatic switch for switching on the backup electricity supplyIn the event of an overload or other problem, he will switch to the reserve in automatic mode, and will also give a signal. Low-power devices are well equipped with an individual automatic switch (about 25 A). Enterprises often have their own individually designed connection scheme. It is not recommended to connect all indoor appliances to a single uninterruptible power supply. This is only necessary for equipment that is too sensitive to electrical surges. Such devices include personal computers, oxygen systems in operating hospitals. No need to connect to UPS TVs, lighting corridors, as the battery charging time may not be enough. If the total power of consumers exceeds the allowable, then there is a risk that the uninterrupted power supply will not turn on at all.
