POINTS OF CAUTION
■POWER INPUT RATING & OPERATIONAL RANGE
Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 50/60 Hz, ≤12VA
24V DC rating: 24V ±10%, ≤3.5W
110V DC rating: 85 – 150V, ≤3.5W
■GENERAL PRECAUTIONS
Before you remove the unit or mount it, turn off the power
supply and input signal for safety.

•How to remove the terminal block cover
Insert the minus tip of a screwdriver into each hole at the
four corners of the cover and pull it to the direction as
indicated below to separate the terminal block cover.
•How to remove the terminal block
The terminal block is separable in two pieces. Loosen two
screws on both sides of the terminal block to separate.
Be sure to turn off the power supply, input signal and
power supply to the output relays before separating the
terminal block.
