Hazard of electrical shock, explosion, and arc flash WARNING ! PRODUCT APPLICATION LIMITATION: Senva products are not designed for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support. Senva is not liable, in whole or in part, for any claims or damages arising from such uses. INSTALLATION 1. This device shall be installed on an enclosure via a 1/2” NPT nipple. 2. Secure relay to enclosure by screwing the provided conduit nut to the 1/2” NPT nipple threads. 3. Connect relay coil to control system by connecting the common (white and yellow conductor) to the control systems common or negative (-) terminal. Then choose either the High (white and black conductor, 120VAC) or Low (white and blue conductor, 24-30VDC/24VAC) depending on control system voltage being sent to the relay coil and connect to positive (+) terminal of the control system. 4. Connect relay contact wires to the application load being controlled by this relay. This will differ between SPDT and SPST contact arrangements. See wiring diagrams at the end of this guide. 5. For relays with status output (PRU1CM and PRU1SM), con- nect (gray conductors) to control system terminals that will be monitoring status of application load. 6. For relays with the Hand/Off/Auto (HOA)(PRU1S and PRU1SM) switch, leave switch in AUTO to control application load from control system driving relay coil. Put HOA in HAND to bypass control system and turn on application load. Putting the switch in OFF will not allow application load to turn on. Disconnect, lock out and tag out all power supplies during installation 3PZS Revised 07/06/2020 Document #152-0415 IMPORTANT WARNINGS • Equipment monitored/operated by this device may start without warning.
