Removal Of Existing Panel; Installation Of New Control Panel; Wiring Installation - Trane Symbio CVRF Installation Instructions Manual

Figure 3. Typical UCP2 before retrofit

Removal of Existing Panel

Remove the existing UCP2 panel. The existing brackets on the
chiller will be reused to mount the new control panel.

Installation of New Control Panel

Install the new control panel using existing hardware to mount
it to the UCP2 brackets.

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. Table 6, p. 13
details the "before and after" of wires from the original panel to
the new panel. Also refer to the connection and schematic
diagrams listed in "Wiring Diagram Matrix," p. 46
detail.

For 50 Hz applications, the control power transformer (1T1) is
supplied as a 60 Hz application. To convert from 60 Hz to 50
Hz, the following step must be performed: move wire 2H from
H3 on 1T1 to H2.
If you have wired a temporary thermostat and 115 Vac power
source to the oil heater leads, wait to connect these wires until
the Tracer® AdaptiView™ retrofit is complete to avoid too
much cooling of the oil.
The information in Table 6, p. 13
that exited the old control panel is to be rewired in the new
factory panel. Also refer to the connection and schematic
diagrams listed in "Wiring Diagram Matrix," p.
