POINT I/O 4 Channel High Density Current Input Module Installation Instructions
Install the Module
The module can be installed before or after base installation. Make sure that the mounting base is correctly keyed before installing the module into the mounting base. In addition,
make sure that the mounting base locking screw is positioned horizontal reference to the base.
1.
Using a bladed screwdriver to 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.
2.
Verify that the DIN rail locking screw is in the horizontal position. if the locking mechanism is unlocked, you cannot insert the module.
3.
Insert the module straight down into the mounting base and press to secure. The module locks into place.
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 wirings. 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.
Rotate the terminal block into the wiring base until it locks itself in place.
3.
If an I/O module is installed, snap the RTB handle into place on the module.
WARNING:
When you insert or remove the module while backplane power is on, an electric arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.
Turn the keyswitch to align the
number with the notch.
