POINTS OF CAUTION

GENERAL
• 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 and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +60°C (23
to 140°F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.
WIRING
• Do not install cables (power supply, input and output) 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.

INSTALLATION

DIN RAIL MOUNTING

WALL MOUNTING
Refer to the External Dimensions in the next page.

TERMINAL CONNECTIONS

Connect the unit as in the diagram below or refer to the
connection diagram label on the unit side.
Do not interconnect negative sides of input and output
terminals (via grounding terminals e.g.) as they are not of the
same potential level.
Ground the terminal 6 for RFI protection if necessary. When
grounded, dielectric strength between output signal line and
ground is of 50V DC, though it is of 500V AC when not
grounded.
