2 [A] Ambient operating temperature [°C] – During operation, parts of electrical sw itching devices carry hazardous voltages. – Before working on the device, disconnect the power. – Please observe the safety regulations of electrical engineering and industrial safety and liability associations. Disregarding these safety regulations may result in death, serious personal injury or damage to equipment. – Startup, assembly, modifications, and upgrades m ay only be carried out by a skilled electrical engineer. – For emergency stop applications, the machine must be prevented from restarting automatically by a higher-level control system. – Protective covers must not be removed when operating electrical switching devices. – In the event of an error, replace the device immediately. – Repairs, especially if the housing must be opened, may only be carried out by the manufacturer or authorized persons. Otherwise the warranty is invalidated. When operating relay modules, the operator must meet the requirements for noise emission for electrical and electronic equipment (EN 61000-6-4) on the contact side and, if required, take appropriate measures.

9 A1, A2: Supply voltage connection

10 65-66: Alarm contacts Function When the 24 V DC operating voltage is applied at terminal blocks A1-A2 or is led via the DIN rail connector, the "Power" LED lights up. When a 24 V DC voltage is applied at input K1-K2 (or via the DIN rail connector), both relays are activated. The LEDs light up and the contacts for enabling current paths 27-28, 37-38, 47-48, and 57-58 close. Alarm contacts 15-16 and 65-66 open. If the voltage is switched off at input K1-K2, the enable contacts open and the alarm contacts close after the set time has elapsed.
