ity.
•Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 1W
■GENERAL PRECAUTIONS
•Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■ENVIRONMENT
