For reliable and safe-to-touch contacts, strip the cable ends as follows: Screw connection (PSR-SCF-.../URM/4X1/2X2): 7m m Spring-cage connection (PSR-SPF-.../URM/4X1/2X2): 10 mm © PHOENIX CONTACT 05/2006 – During operation, parts of electrical switching 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 may only be carried out by a skilled electrical engineer. – 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. – According to EN 50205, only one N/O contact and one N/C contact may be used as positively driven contacts. 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. /G41 /G31 /G41 /G31 /G41 /G32 /G41 /G32 /G31 /G33 /G31 /G34 /G32 /G33 /G32 /G34 /G33 /G33 /G33 /G34 /G34 /G33 /G34 /G34 /G35 /G31 /G35 /G32 /G36 /G31 /G36 /G32
