The conditions of safe use:
a.
The equipment shall be installed in an enclosure that provides a
degree of protection not less than IP 54 in accordance with
IEC/EN 60079-15 and accessible only by the use of a tool.
b.
Devices are for use in an area of not more than pollution
degree 2 in accordance with IEC/EN 60664-1.
c.
Provisions shall be made, either in the equipment or external to

exceeded by the transient disturbances of more than 140% of
the peak-rated voltage.
Installation instructions
a. When wiring the relay contact (R), digital input (DI), and power
inputs (P1/P2), we suggest using AWG (American Wire Gauge) 12-28
(0.0804-3.31 mm²) as a cable and the corresponding pin-type cable
terminals. The connector can withstand a maximum torque of 4.5 inch-
pounds.
b. Conductors suitable for use in an ambient temperature of 85°C must
be used for the power input terminal block.
c. The cross-sectional area of the earthing conductors shall be at least
3.31 mm²
C1D2 Information
