rail.

■ GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.

■ ENVIRONMENT

• Indoor use.

• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.

• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 0 to 90% RH
in order to ensure adequate life span and operation.

■ WIRING

• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).

• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

• Install lightning surge protectors for those wires connect­ed to remote locations. For 24V DC power supply line,
choose a surge protector with its maximum surge voltage
40V or less between lines. Recommended M-System mod­el: MDP-D24.
