INSTALLATION
STEP 1: MOUNTING THE DEVICE
1)Mountthedeviceinthedesiredlocaon(seestep1).
2)Openthelidandroutethecablethroughthestrainreliefandconnectthe
wirestotheterminalblock(s)(seestep2).
3)Thedeviceisnowreadyforconguraon.
WARNING!Applypoweronlyaerthedeviceisproperlywired.
1)Selectthemounnglocaon(duct,wall,panel).
2)Usethedeviceasatemplateandmarkthescrewholes.
3)Mountwithappropriatescrews.
