POINT I/O 5V DC and 24V DC Very High Speed Counter Module Install the Mounting Base To install the mounting base on the DIN rail, proceed as follows: ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.
POINT I/O 5V DC and 24V DC Very High Speed Counter Module 9 1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number required for the type of module being installed aligns with the notch in the base. Turn the keyswitch to align the number with the notch (position 3 is shown). 44009 2. Make certain the DIN rail locking screw is in the horizontal position. You cannot insert the module if the locking mechanism is unlocked.
POINT I/O 5V DC and 24V DC Very High Speed Counter Module Install the Removable Terminal Block A removable terminal block (RTB) is supplied with your wiring base assembly. To remove, pull up on the RTB handle. This allows the mounting base to be removed and replaced as necessary without removing any of the wiring. To reinsert the removable terminal block, proceed as follows: 1. Insert the end opposite the handle into the base unit. This end has a curved section that engages with the wiring base. 2.
POINT I/O 5V DC and 24V DC Very High Speed Counter Module 11 Remove a Mounting Base To remove a mounting base, you must remove any installed module, and the module installed in the base to the right. Remove the removable terminal block, if wired. 1. Unlatch the RTB handle on the I/O module. WARNING: When you connect or disconnect the Removable Terminal Block (RTB) with field side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations.
