1. Safety information
1.1 Installation and commissioning
When laying wires, please ensure that no damage occurs to any of the constructional
fire safety measures presented in the building.
The controller should not be installed in rooms where easily inflammable gas mixtures
are present or may occur.
The permissible environmental conditions can’t be exceeded at the site of installation.
Before connecting the device, please make sure that the power supply matches the
specifications that controller requires.
All devices connected to the controller must conform to the technical specifications of
the controller.
