Packaginng, transportation, storage
Description The module is packed in a paper box. This documentation is also part of the package. The outer packaging is carried out according to the scope of the order and the method of transport in a transport package provided with labels and other data necessary for transport. The product must not be exposed to direct weather conditions during transport and storage. Malting of the product is only allowed in clean rooms without conductive dust, aggressive gases and vapors. The most suitable storage temperature is 20 ° C
Description The module does not require any maintenance under general installation conditions. The operations in which a part of the module has to be dismantled must always be carried out with the supply voltage disconnected.
Notice Because the module contains semiconductor components, it is necessary to follow the principles for working with electrostatic sensitive components when handling the removed cover. It is not allowed to directly touch the printed circuit boards without protective measures !!!
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Notice You must meet all the conditions of this documentation before turning on the system. The system must not be put into service unless it has been verified and confirmed that the machinery meets the requirements of Directive 89/392 / EEC, in so far as it applies to it. Documentation subject to change.
