figure below.
Mounting the Terminal Blocks
The insulation of the removable terminal blocks protect against direct contact. If you
replace the terminal blocks, observe the rated insulation voltage. If the rated voltage
greater than 50 V AC, proceed as follows:
1.
Switch off the voltage.
2. Connect the terminal blocks or disconnect the terminal blocks.
CORRECT: Device snapped on vertically. INCORRECT: Device snapped on from the side.
