Chapter 5: Expansion Box and Virtual Expansion Box Installation
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 CS_Ax or CS_Bx on the EDGE 4IN-2V-8DO.
3. Connect the voltage sources (L1) at one side of CS_Ax or CS_Bx.
4. From another side CS_Ax or CS_Bx, connect one side of the load.
5. From another side of the load, connect to the main voltage supply return (L2/N).
IMPORTANT: The maximum voltage on the current sensor is 415Vac. The maximum current allowed is
16A at 415Vac.
WARNING
High voltage current sensor (CS_Ax, CS_Bx) terminal blocks accept a gage range
from 12AWG (diameter of 2.05mm or cross sectional area of 3.30mm
2
) to 14AWG
(diameter of 1.62mm or cross sectional area of 2.08mm
2
). Only copper wire can be
used with EDGE 4IN-2V-8DO. The conductor can be stranded or single-stranded.
See 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 600V and a minimum temperature rating of 90°C is used for
the wires at 415Vac. 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 connected on the current sensors, use a tightening torque
from 0.7N*m (6.2lbf*in) to 0.8N*m (7lbf*in) to fasten a wire gage from 12AWG
(diameter of 2.05mm or cross sectional area of 3.30mm
2
) to 14AWG (diameter of
1.62mm or cross sectional area of 2.08mm
2
).
