SRMON Printed Circuit Board Bushings All I O on the SSRMON is available with screw terminal connectors for ease of harness assembly The screw connectors can accept up to 14 AWG wire The power alarm and ground wires are wired to the screw terminal block In the case of the interrupted input version the control input is wired to the screw terminal connector located at the top left hand corner of the board The AC Load Side and Signal connections should be wired as shown in Figure 2 below It is good practice to keep the AC Load Side wires away from the Control and Alarm wires to prevent any power line noise from coupling into them 3 3 Wiring Diagram Figure 2 Interrupted Input Version Continuous Input Version 1 SOLINOR ISS Eg HOLNOW HSS 0 0 ODI J Oo inal Exe ODI Oo ACI ANN cA 39VL10A HOIH a CI O Z N AC 04 O am zi lt ap CONTROL i Ya CAS 3 Sef bi OSA ko ll CONTROL e INPUT ils JIVLTOA HSIH ONE AC LOAD e SIDE 4 S x aaa amp A y LO he SIDE INPUT A AC2 Se E 2ISNVA 5 sei d c Am LO a z PASO __ AC2 Zz FA NO 9 Ld 0 MO NUI 2 GND vA gt x 20 A zZ d m com amp a gt z LARI E lt 3 4 Limited Warranty Copyright 1998 NUWAVE TECHNOLOGIES SSRMON User Manual Page 4 NuWave Technologies Inc warran
