Chapter 2: Basic connections
NOTICE
For the small terminal blocks used for inputs and low voltage outputs, use a
tightening torque from 0.5N*m (4.43lbf*in) to 0.6 N*m (5.2lbf*in) to fasten a wire gage
from 14AWG to 16AWG.
WARNING
If rigid metal tubes are used, ensure the rigid tubes are correctly grounded.
Connecting the power supply
Before You Begin
IMPORTANT: Install a disconnect switch to interrupt Power to L1 and N/L2 electric Power lines before
connecting the system’s main input on the power supply. It must be in close proximity to
the equipment and within easy reach of the operator. It must be marked as the disconnect-
ing device for the equipment.
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.
CAUTION
Disconnect supply before servicing
1. From the Power source, follow the wiring diagram to connect the main voltage supply to the sys-
tem’s main inputs on the power supply.
2. Open the disconnecting switch or breaker before wiring.
3. Plug the wires (L1 to L1, L2/N to L2/N, Earth to Earth) from the power supply into a Power source
(main voltage supply).
4. Correctly ground the system by using a protection Earth configuration.
5. 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 120 W (6-Slot Expansion Box) or 60 W (3-Slot Expansion Box). Size your circuit breaker
and the wires in accordance with local and national safety codes. A minimum voltage rating
of 300V and a minimum temperature rating of 90°C is used for the wires.
NOTICE
For the black terminal blocks used on the power supply, use a tightening torque
from 0.9N*m (7.96lbf*in) to 1.13N*m (10lbf*in) to fasten a wire gage from 14 AWG
to 18AWG.
