4. CONNECTIONS
4.1 Terminal Board Arrangement
The terminal boards shown in the following figure are of recorders with the options (alarm
remote contacts and communications interface).
*The mechanical relay “c” contact output is consisted of three terminals of N.O, COM and N.C.
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.

Removed terminals have to be remounted to the recorder to which they were originally mounted.
Mounting them to other recorders may cause a malfunction in scaling.
The input terminal and alarm terminal blocks are removable.
