Chapter 2: Basic connections
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 relay 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 relay outputs. 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.
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 Technical Specifications, page 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 to
14AWG.
