The SIG7404 module is to be installed in a 19" rack. Do not cover the device's ventilation grids; therefore, give
some space for the future presence of other modules to be kept at the correct distance (both above and below
the SIG7404 module). Install the device, connect the input and output cables and, if necessary, connect the
Ethernet port (use the description of the inputs/outputs of Chapter 2. PRODUCT DESCRIPTION).
ATTENTION: Before connecting the power supply cable, switch the encoder off by means of the power switch
(OFF).
