[X09] Transmission supply voltage 24 VDC and STO

Note only for devices with rev.<4.00:

NOTE
Material damage!	Material damage due to overvoltage! An overvoltage at the connections X08 and X09 (24 VDC) is not monitored and damages the device¹⁾. ( Steps to prevent: Comply with the specifications for the electronics supply voltage 24 VDC. (24 VDC ± 15 %, ripple max. 5 %)

NOTE

Material damage!

Material damage due to overvoltage!

An overvoltage at the connections X08 and X09 (24 VDC) is not monitored and damages the device¹⁾. (

Steps to prevent:

Comply with the specifications for the electronics supply voltage 24 VDC.
(24 VDC ± 15 %, ripple max. 5 %)

1)	Devices with Rev. <4.00 do not have STO certification (no TÜV logo on the nameplate) and do not have overvoltage monitoring. An overvoltage > 24 VDC ± 15% at 24V or STO will destroy the device.
