ArmorPoint 24V dc Output Modules, Series A ATTENTION 3 Environment and Enclosure This equipment is intended for use in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
ArmorPoint 24V dc Output Modules, Series A Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment.
ArmorPoint 24V dc Output Modules, Series A 5 Install the mounting base as follows: 1. Lay out the required points as shown above in the drilling dimensions drawing. 2. Drill the necessary holes for #8 (M4) machine or self-tapping screws. 3. Mount the base using #8 (M4) screws. 4. Ground the system using the ground lug connection. The ground lug connection is also a mounting hole.
ArmorPoint 24V dc Output Modules, Series A Install the ArmorPoint Digital Output Module To install the ArmorPoint digital output module, proceed as follows. 1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number 1 aligns with the notch in the base. 2. Position the module vertically above the mounting base. The module bridges two bases. Module bridges two bases. 1738-OB8EM12/A 24V dc Out 0 2 1 3 MOD NET 0 1 2 3 4 6 5 7 4 5 6 7 43771 3.
