A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Xantrex Technology Link 2000, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Xantrex Technology Link 2000 one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.

Unfortunately, only a few customers devote their time to read an instruction of Xantrex Technology Link 2000. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of Xantrex Technology Link 2000 should contain:
- informations concerning technical data of Xantrex Technology Link 2000
- name of the manufacturer and a year of construction of the Xantrex Technology Link 2000 item
- rules of operation, control and maintenance of the Xantrex Technology Link 2000 item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Xantrex Technology Link 2000 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Xantrex Technology Link 2000, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Xantrex Technology service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of Xantrex Technology Link 2000.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Xantrex Technology Link 2000 item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

    7 SETUP The LINK 2000 has been set up with default values chosen to work with a typical system. Normally the only values that must be changed are: 1) Battery capacity (page 9) 3) Battery type (liquid or gel) (F02 page 1 1). 2) Ambient T emperature (F03 page 11) 4) Peukert's exponent (F08 page 13). The SETUP BUTTON is used to access the functio[...]

    8 INVERTER SETUP IDLE MODE: The default value is 4 watts. This means it takes a 4-watt AC load to turn the inverter on from its low power idle mode. Setting a value of 0 watts means the inverter is always on. The low power idle current is about 0.25 amps. When idle mode is set to 0 W the current consumption goes up to about 0.9 amps. Range = 0 W , [...]
