CE Compliance Requirements
Must be installed inside a metal enclosure rated at IP20
minimum.
Energy Management Applications
For energy management only (low voltage Class 2), the
TC Compact may be mounted on a flat surface.
Applications Requiring a Secure Enclosure
Mount the TC Compact inside a listed enclosure along
with a Service Box and Sidewall Kit, if needed.
Smoke Control Application
Requirements
CAUTION:
The 115V or 230V PX Series Service Box is
required for UL864 and NFPA92A compliant
installations. For more information, see the
PX Series Service Box Assemblies
Installation Instructions (553-131).
For non-UL864 and non-NFPA92A
applications, any 24 Vac UL Listed Class 2
transformer may be used.
For smoke control applications, the TC
Compact must be connected to the
Automation Level Network (ALN) through an
Ethernet switch that is UL Listed for Fire
Signaling. ALN and FLN circuits are
supervised.
For smoke control applications, mount the TC Compact
inside a 19" or 34" PX Series enclosure (PXA-ENC19 or
PXA-ENC34). For more information, see the 19" and 34"
PX Series Enclosure Assemblies Installation Instructions
(553-130).
Service Modem Kit (538-915) is required for remote
connection to the HMI of a TC Compact running smoke
control applications. The modem, serial cable, and surge
suppressor must be installed inside the 19" or 34" PX
Series Enclosure with a Service Box.
Installation Instructions
WARNING:
Turn OFF AC power at the circuit breaker
panel.
CAUTION:
UL Listings require that NEC Class I and
Class II wiring be kept separate from each
other. Use separate conduit and cable tie bars
to separate Class I Digital Output (DO) wires
from all other Class II wiring.
Securely fasten the TC Compact so that it
does not come loose when point connectors
are removed...
If you need to reinsert one of the mounting
tabs, see the TC Compact Series Owner’s
Manual (588-682) for instructions.
The TC Compact may be mounted either vertically (with
24 Vac and DOs on the right) or horizontally (with 24
Vac and DOs at the top).
Options for Mounting the TC Compact
Select one of the following options for installation:
• Mount the controller on a DIN rail by using the
four slide-out mounting tabs.
• Fasten the controller to a surface or enclosure
backplane with screws
Option 1: Mounting the Controller on a DIN
Rail
To provide a minimum clearance for wiring,
allow 6 inches (15 cm) from the center of the
DIN rail to obstructions on either side.
Installing the DIN Rail
Do the following if the DIN rail is not already installed:
1. Align and level the DIN rail on the mounting surface
or the backplane of the enclosure.
2. Mark the position of the mounting holes at either end
of the DIN rail.
3. Using wall anchors, if necessary, attach the DIN rail
to the surface or the backplane.
For longer DIN rails, use one mounting
screw per running foot of DIN rail.
