Installation
18 SO-SVN037A-EN
Connect Input Power Wiring to 1A2 Power
Supply
Notes:
• Proceed directly to the next stage of the installation
process if the 1A2 power supply was already in place as
part of the previous CH530 control system.
• The full schematic wiring diagram can be found in
Figure 69, p. 36 of this manual.
1. Attach a Red 16 AWG wire between J2-1 on the 1A2 power
supply and 1T1-X2.
2. Attach a Red 16 AWG wire between J2-2 on the 1A2 power
supply and 1T1-X1.
3. Attach a Green 16 AWG wire between J2-3 on the 1A2
power supply and any available ground terminal on the
1X1 terminal block.
Notes:
• Gn Green wire
• R Red wire
Routing New Wire Into and Out of the
Control Panel Enclosure
• Make use of the spare factory knock-outs that are available
on the right-hand end of the control enclosure, for routing
all required wiring runs from the Symbio 800 controller and
the 1A2 power supply out to the connection points on the
display.
• Plastic grommets are provided in the upgrade kit to line the
edges of the knock-outs used.
Note: If a specific retrofit situation has made it necessary to
mount the display arm on the left-hand panel bracket or
the left-hand end of the enclosure, please note that all
of the cables provided within the display upgrade kit
are long enough to allow utilizing the spare factory
knock-outs that already exist on the back of the control
panel enclosure.
Wiring Connections to the Display and
Symbio 800 Controller
Note: Also refer to the full schematic wiring diagram located
in Figure 69, p. 36 of this manual.
1. Ethernet communication cable installation:
a. Attach the head of the Ethernet cable to the display.
b. Route the cable through the wire channel on the display
arm.
Important: Leave enough slack in the cable to allow the
display arm to be moved through its full range
of motion without placing a strain on the cable
or the terminal connections.
c. Take the cable around the back side of the control
enclosure and feed it into the cabinet through one of the
spare factory provided cable knock-outs.
d. Insert the cable end into the Ethernet port on the
Symbio 800 controller.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state/national electrical codes.
