MicroLogix™ 1500 Programmable Controller Base Units 5 Overview Install your controller using these installation instructions. ATTENTION ! Do not remove protective debris strips until after the base and all other equipment in the panel near the base is mounted and wiring is complete. Once wiring is complete, remove protective debris strips and install processor unit. Failure to remove strips before operating can cause overheating.

MicroLogix™ 1500 Programmable Controller Base Units 7 Hazardous Location Considerations This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous locations only. The following WARNING statement applies to use in hazardous locations. WARNING ! EXPLOSION HAZARD • Substitution of components may impair suitability for Class I, Division 2. • Do not replace components or disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
MicroLogix™ 1500 Programmable Controller Base Units Environnements dangereux Cet équipement est conçu pour être utilisé dans des environnements de Classe 1, Division 2, Groupes A, B, C, D ou non dangereux. La mise en garde suivante s’applique à une utilisation dans des environnements dangereux. MISE EN GARDE DANGER D’EXPLOSION • La substitution de composants peut rendre cet équipement impropre à une utilisation en environnement de Classe 1, Division 2.
MicroLogix™ 1500 Programmable Controller Base Units 9 Mounting the Controller General Considerations Most applications require installation in an industrial enclosure (Pollution Degree 2) to reduce the effects of electrical interference (Over Voltage Category II) and environmental exposure. Locate your controller as far as possible from power lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and AC motor drives.
MicroLogix™ 1500 Programmable Controller Base Units Mounting Dimensions A B C Table 6 Dimensions Dimension 1764-24AWA 1764-24BWA Height (A) 138 mm (5.43 in.) Width (B) 168 mm (6.62 in.) Depth (C) 87 mm (3.43 in.) 1764-28BXB Controller Spacing The base unit is designed to be mounted horizontally, with the Compact™ expansion I/O extending to the right of the base unit. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown below.
MicroLogix™ 1500 Programmable Controller Base Units 11 Using a DIN Rail The base unit and expansion I/O DIN rail latches lock in the open position so that an entire system can be easily attached to or removed from the DIN rail. The maximum extension of the latch is 15 mm (0.67 in.) in the open position. A flat-blade screw driver is required for removal of the base unit. The base can be mounted to EN50022-35x7.5 or EN50022-35x15 DIN rails. DIN rail mounting dimensions are shown below.
MicroLogix™ 1500 Programmable Controller Base Units To remove your base unit from the DIN rail: 1. Place a flat-blade screwdriver in the DIN rail latch at the bottom of the base unit. 2. Holding the base unit, pry downward on the latch until the latch locks in the open position. This releases the base unit from the DIN rail. Using Mounting Screws Mount to panel using #8 or M4 screws.
MicroLogix™ 1500 Programmable Controller Base Units 13 To install your base unit using mounting screws: 1. Remove the mounting template from the inside back cover of this document. 2. Secure the template to the mounting surface. (Make sure your base unit is spaced properly, see “Controller Spacing” on page 10). 3. Drill holes through the template. 4. Remove the mounting template. 5. Mount the base unit. 6.
MicroLogix™ 1500 Programmable Controller Base Units Wire Requirements Table 8 Wire Type Recommendation Wire Type Wire Size (2 wire maximum per terminal screw) Solid Cu-90°C (194°F) #14 to #22 AWG Stranded Cu-90°C (194°F) #14 to #22 AWG Wiring torque = 1.13 Nm (10 in-lb) rated; 1.3 Nm (12 in-lb) maximum ATTENTION ! Be careful when stripping wires. Wire fragments that fall into the controller could cause damage.
MicroLogix™ 1500 Programmable Controller Base Units 15 Spade Lug Recommendation The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and output terminals of the MicroLogix 1500 base unit are designed for the following spade lugs. The terminals will accept a 6.35mm (0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.
MicroLogix™ 1500 Programmable Controller Base Units Grounding the Controller ATTENTION ! All devices connected to the RS-232 channel must be referenced to base unit ground or floating. Failure to follow this procedure may result in property damage or personal injury. In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI).
