Reference The input terminal and alarm terminal blocks are removable.
The input terminal block and alarm terminal block (including the remote contacts terminal block) are removable for easy connections. Each terminal block can be taken out by removing two mounting screws. Each terminal block is connected to your recorder by a connector. For mounting or dismounting the terminal block, turn off the power switch to prevent the electric circuits from being damaged.
