Wiring Installation

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.
Unless otherwise indicated, all 115 volt control circuits use, as
a minimum, #16 AWG, 600 volt wire. Be sure to use existing
conduit wherever possible and separate all
115V wiring from any low voltage circuits.
Most wiring will use the existing wires removed and marked
from the original panel and moved to the terminal block in the
new panel. Some wires may need to be connected directly on
a LLID terminal. For all control panel wiring, refer to wiring
diagrams shipped with the kit and to the connection and
schematic diagrams listed in
additional detail.
For 50 Hz applications, the control power transformer (1T1) is
supplied as a 60 Hz application. To convert from 60 Hz to 50Hz,

the following step must be performed: move wire 2H from H3
on 1T1 to H2.
If you have wired a temporary thermostat and 115 volt power
source to the oil heater leads, wait to connect these wires until
the Symbio™ retrofit is complete to avoid too much cooling of
the oil.

Motor Temperature Devices

The new Symbio™ panel comes with the motor winding
temperature input LLID (IA26). This is used for motors that
have RTD-type sensors embedded in the motor windings. If
the motor does not have RTD-type sensors, motor
temperature protection can be accomplished a temperature
sensor which installed in the bulb well of the motor, and
connect to the IPC bus.

Mount Display Arm and Display

1. Secure the arm to the control panel using the
5/16 - 18 x 1-inch hex bolts, 5/16 - inch lock washers, and
5/16 - 18 hex nuts provided. There are pre-drilled holes on
the left and right sides of the control panel; select the side
that's most suitable for your specific application.
Note: There is a production display arm bracket
for
BRK04345 provided that where applicable can be
mounted to the existing control panel mounting
arms. When used, the holes on the unused side(s)
should be plugged.
