Chapter 3: Basic connections
WARNING
If the disconnect 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.
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 the 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.
CAUTION
Disconnect power supply before servicing
3. From the Power source, follow the wiring diagram to connect the main voltage supply to the sys-
tem’s main inputs on the PSU 24V 20W.
4. Open the disconnecting switch or breaker before wiring.
5. Plug the wires (L1 to L1, L2/N to L2/N, Earth to Earth) from the PSU 24V 20W into a power source
(main voltage supply).
6. Correctly ground the system by using a Functional Earth configuration.
7. From The PSU 24V 20W, connect the “+” in the 24V input and connect the “-” in the GND input on
the EDGE Bin Scale.
8. Power on the system and make sure it is receiving Power from the power source.
NOTE: The working voltage range is between 90 Vac and 264 Vac. The system consumes a power
of 20W. Wire in accordance with local and national safety codes. The minimum wires
requirements are : use a minimum voltage rating of 300V and a minimum temperature rating
of 90°C.
IMPORTANT: Make sure to connect same signal identification together and use the same network
from one side to the other.
IMPORTANT: If redundancy supplies are not used, use the Automation bus
Connecting the EDGE Bin Scale to the communication network
The communication bus enables communication between the EDGE Main Controller and the EDGE Bin
Scale (terminal A and terminal B on the Automation network or the Safety network). There are two com-
munication networks available. One of them serves as a backup network.
1. Locate the terminals Automation or Safety on the EDGE Bin Scale you want to connect.
2. Connect the wires from the EDGE Bin Scale to the network.
IMPORTANT: Make sure to connect same identifications together and use the same network from
one side to the other.
