Symbio
210 Controller Power Wiring
The following section provides wiring guidelines for powering the Symbio
210 controller.
Wiring Requirements
To ensure proper operation of the Symbio 210 controller, install the power supply circuit in
accordance with the following guidelines:
•
The controller must receive AC power from a dedicated power circuit.
Important:
Failure to comply may cause the controller to malfunction.
•
A dedicated power circuit disconnect switch must be near the controller, easily accessible by
the operator, and marked as the disconnecting device for the controller.
•
DO NOT run AC power wires in the same wire bundle with input/output wires.
Important:
Failure to comply may cause the controller to malfunction due to electrical noise.
•
18 AWG (0.823 mm
2
) copper wire is recommended for the circuit between the transformer and
the controller.
Connecting the Wires
1. Disconnect power to the transformer.
2. Connect the 24 Vac secondary wires from the transformer to the XFMR 24 Vac and
terminals
on the Symbio 210 controller.
Power On Check
1. Verify that the 24 Vac connector and the chassis ground are properly wired.
2. Remove the lockout/tagout from the line voltage power to the electrical cabinet.
3. Energize the transformer to apply power to the Symbio 210 controller.
4. Observe the cleared Symbio 210 controller when power is applied to verify the power check
sequence as follows:
a. The Status LED blinks red or green while the controller is booting.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
WARNING
Electrocution and Fire Hazards with Improperly Installed and Grounded
Field Wiring!
Improperly installed/grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid
these hazards, the user MUST follow requirements for field wiring installation and grounding
as described in NEC and local/state electrical codes. All field wiring MUST be performed by
qualified personnel. Failure to follow these requirements could result in death or serious injury.
NOTICE
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Failure to use copper
conductors could result in equipment damage.
