IMPORTANT: The maximum voltage on the discrete outputs is 240Vac. The maximum current allowed is
0.5A at 240Vac. For each discrete outputs group, the maximum current is 2A.
WARNING
High voltage discrete output (OUT-Ax / OUT-Bx and COMM-A / COMM-B) terminal
blocks accept a gage range from 12AWG (diameter of 2.05mm or cross sectional
area of 3.30mm
2 ) to 16AWG (diameter of 1.29mm or cross sectional area of
1.30mm 2 ). Only copper wire can be used with EDGE 4IN-2V-8DO. The conductor can be stranded
or single-stranded.
WARNING
Do not use stranded wire with the J23A, J24A terminal block plug-in type 1832552:
GMVSTBR 2,5/ 5-ST-7,62.
See the Technical Specifications page to know the EDGE 4IN-2V-8DO ratings according to the load used
and the possible load configuration. Refer to your local building code to determine the type and quality of
cable required. A minimum voltage rating of 300V and a minimum temperature rating of 90°C is used for
the wires at 240Vac. See the EDGE 4IN-2V-8DO wiring diagrams to know how to manage the use of
many phases from the main voltage supply and how to wire loads in parallel.
NOTICE
For the terminal blocks used for discrete outputs, use a tightening torque from
0.5N*m (4.43lbf*in) to 0.6 N*m (5.2lbf*in) to fasten a wire gage from 12AWG (diameter
of 2.05mm or cross sectional area of 3.30mm
2 ) to 16AWG (diameter of 1.29mm or
cross sectional area of 1.30mm 2 ).
Connecting the Current Sensors of Discrete Outputs
The EDGE 4IN-2V-8DO has 8 current sensors (CS_Ax, CS_Bx) to read the current on the relay or the
contactor contact. The maximum current allowed by these outputs is 16A at 415Vac.
IMPORTANT: This module cannot read DC voltage
IMPORTANT: A disconnect switch must be installed to interrupt Power to L1 and N/L2 electric Power
lines before connecting the system’s main inputs on the discrete outputs. It must be in
close proximity to the equipment and within easy reach of the operator. It must be marked
as the disconnecting device for the equipment. From the Power source, follow the wiring
diagram to connect the main voltage supply to the EDGE 4IN-2V-8DO. AP/Cumberland
recommends using a DPST disconnecting switch in series with a breaker. In the case of
the use of a SPST disconnecting switch, connect SPST disconnecting switch to cut the
Hot line with a Neutral circuit case.
IMPORTANT: The SPST disconnecting switch circuit is allowed only in North America under 120Vac.
Over 120Vac in North America and whatever the voltage in International markets, only the
DPST disconnecting switch is allowed.
