Chapter 5: Expansion Box and Virtual Expansion Box Installation
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
1. From the Power source, follow the wiring diagram to connect the main voltage supply to the relay
outputs.
2. Locate the “RELAY(x)” terminals on the Module.
3. Connect the voltage source (L1) wire needed to switch in the terminal block named “RELAY – COM”
4. Connect one load from the relay output: terminal - RELAY(x) - NO or terminal RELAY(x) – NC if it is
available.
5. From the load, connect to the main voltage supply return (L2/N).
IMPORTANT: The maximum voltage on the relay outputs is 240Vac. The maximum current allowed
is 12A with NO CONTACT. The maximum current allowed is 10A with NC CONTACT.
The minimum permissible load on the relay outputs is 0,2A.
See the Technical Specifications Appendix to know the resistive load, motor load, and relay 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.
AP/Cumberland recommends the use of fuse in series at the output of a relay with a circuit breaker.
NOTICE
For the terminal blocks connected on the power relays, use a tightening torque
from 0.7N*m (6.2lbf*in) to 0.8N*m (7lbf*in) to fasten a wire gage from 10AWG
(diameter of 2.58mm or cross sectional area of 5.26mm
2
) to 14AWG (diameter of
1.62mm or cross sectional area of 2.08mm
2
).
Connecting an EDGE Variable Output module (SSR)
Before You Begin
IMPORTANT: An external or circuit breaker and a disconnecting switch must be installed to interrupt
power to L1 and N/L2 electric power lines before connecting the system’s main sector
input on the variable outputs (SSR). 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 sector to the variable outputs
(SSR).
