Chapter 5: Expansion Box and Virtual Expansion Box Installation
WARNING
If the fixture has an earth connection, connect it directly to the electrical distribution
panel.
Connecting Discrete Outputs
The EDGE 4IN-2V-8DO has 8 discrete outputs (OUT-Ax / OUT-Bx and COMM-A / COMM-B) to control
relay or contactor coils. The maximum current allowed by these outputs is 0.5A from 24Vac to 240Vac.
IMPORTANT: This module cannot control DC coils.
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.
WARNING
Installation must only be performed by qualified service personnel.
WARNING
If the disconnecting switch or the circuit breaker is used as a sectioning device, the
device must be correctly identified with which function of the controller opens the
circuit. The Off or Stop and On position must be clearly identified on the sectioning
device.
CAUTION
Disconnect supply before servicing
WARNING
Lock the enclosure when wiring is complete or when servicing.
1. From the Power source, follow the EDGE 4IN-2V-8DO wiring diagram to connect the main voltage
supply to the EDGE 4IN-2V-8DO.
2. Locate terminal COMM-A or COMM-B on the EDGE 4IN-2V-8DO.
3. Connect the voltage sources (L1) to each input (COMM-A and COMM-B).
4. From each output OUT-Ax / OUT-Bx, connect one side of the relay or the contactor coil.
5. From the other side of the relay or the contactor coil, connect to the main voltage supply return (L2/
N).
