Control Circuit Terminal Functions
NOTICE: The terminals HC, H1, H2 are used for the Safe Disable function which cuts the output voltage in
less than 1 ms if at least one of the inputs H1 or H2 is opened. It is designed in accordance with the ISO/EN
13849-1, Safety Category 3, PL d, and IEC/EN 61508, SIL2. It can be utilized to perform a safe stop as
defined by the IEC/EN 61800-5-2, stop category 0. Do not remove the wire link between HC, H1, or H2
unless the Safe Disable function is used. Refer to the Technical Manual when using this function.
NOTICE: The wiring length to the terminals HC, H1 and H2 should not exceed 30 m.
