3 Electrical Installation
There are three DIP switches, S1 to S3, located on the terminal board
SW1 Switches analog input A2 between voltage and current input
SW2 Enables or disables the internal RS422/485 comm. port terminal resistance.
Used to select sourcing (PNP)/sinking (NPN, default) mode for the digital inputs (PNP requires
SW3
external 24 VDC power supply)

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 EN954-1, safety category 3 and EN61508, SIL2. It
and can be utilized to perform a safe stop as defined by the EN60204-1, 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.
