Introduction
Congratulations on your purchase of a Powersafe TMC-500W thermal
management system. These units offer unsurpassed protection
against component over-temperature failure. The unit has been built
tough for indoor and outdoor use on a range of switchboard
enclosures.
If a switchboard generates too much thermal energy the operation of
circuit protection devices is adversely affected, creating a potential
safety risk. The TMC-500W has been proven to dissipate 500W of
heat losses at 20K (difference between internal and external
temperature, tested at 400C ambient) generated by internal
switchboard components. Many switchboard components need to be
de-rated in an environment above 400C or below 00C. Refer to
component manufacturer's specification for applicable
characteristics. Powersafe thermal management systems also
incorporate a heater for humidity and low-temperature control.
Powersafe thermal management systems have been designed
specifically with safety in mind ensuring no exposed conductive parts
and utilizing Extra-low voltage (ELV) fans. The TMC-500W has been
thoroughly tested in harsh working environments to measure
performance. The device must be installed and operated as per the
instructions in this manual.
It is the user's responsibility to ensure that the TMC-500W is used
and installed as per any Australian standards, local authority
requirements and all other standards or requirements to satisfy the
conditions of the location and functionality of the unit and its use.
Please refer to the standards that the TMC-500W has been designed
and manufactured to comply with and to ensure that it is
appropriate for its intended use.
Powersafe Thermal Management Systems are the industry leading solution for switchboard thermal
performance and safety

•The TMC-500W.1 must be installed, wired and tested by a
licenced electrician.
•Prior to installation, the assembly must be inspected for any
damage during transport. Check all connectors are firmly in
place and fasteners have not come loose.
•The enclosure to which the device is to be fitted must be in a
location that allows sufficient air flow i.e. not in a small
enclosed room.
•The assembly should be mounted horizontally on a flat, clean
surface without defects to ensure a sufficient seal. The
mounting surface may require reinforcing to prevent warping.
•To ensure optimal performance, the enclosure to which the
device is fitted should be completely sealed to minimum IP54.
•The 150W power supply unit has been selected for its technical
parameters. In case of replacement, replace only with like for
like product.
•Install power supply inside enclosure in a location away from
direct heat sources.
•Install heater in bottom corner of enclosure in a location
allowing sufficient air flow and away from combustible
materials.
Installation Precautions:

Installation Instructions:
Step 1: Isolate, test and lock out
power from the enclosure in which
the assembly is to be installed.
Step 2: Select a suitable location in
the top of the enclosure for
installation. Ensure there is
enough clearance inside to get the
mounting bracket in. The assembly
requires 150mm recessed height
inside the enclosure and 200mm
height above for air flow. Ensure
TMC controller is away from direct
heat source.
Step 3: Use mounting plate and
measurements provided to mark
out enclosure for cutting. Take
precautions to prevent swarf/
debris from falling onto internal
components. Debur any sharp or
proud edges. Treat any raw metal
surfaces for rust prevention.

Step 4: Ensure rubber seals are in place in
the bottom of heatsink plate and around the
base of orange cover and are in good
condition before inserting TMC 500W
assembly into enclosure. If internal access is
limited, the 24V supply to the TMC
controller will need to be connected prior to
insertion.
Step 5: Insert steel mounting plate from
inside enclosure into place on the 12x
grubscrews. Secure 11x grub screws with an
M5 panel washer, spring washer, and
standard nut. Do not use nyloc nuts as this
can force the grubscrews through the
aluminium heatsink plate. Torque nuts to
1Nm.
Step 6: Connect a minimum sized 4mm2
earth wire with ring terminal/ lug to the
remaining grub screw between a panel
washer and a standard M5 washer, secured
with a spring washer and standard nut. The
assembly should only be earthed at one
point.

Step 8: 240V and 24V field wiring is required to be made
during installation. Use appropriately rated cable and
circuit protection to relevant standards. Use cable
protection and segregation applicable to installation.
Assembly and Power Supply Unit must be connected to
earthing system. Ensure wiring and components are
away from sources of heat.
Step 9: Conduct and record electrical tests of field wiring
prior to powering up assembly. Check earth continuity of
exposed parts of assembly <0.5 Ohms. Do not apply test
voltages above operational voltage to assembly
components. Check polarity of all field wiring to prevent
damage to components.
Step 7: Mount the Power Supply Unit on DIN rail with
the brackets provided. Ensure location is not accessible
without the use of tools and/or key and is away from
sources of heat. Mount the heater on DIN rail in the
bottom corner of enclosure and clear of wiring, circuit
protection and other heat sensitive components.

Step 10: Test operation of assembly. Press and hold test
button while system cycles through internal and external
fan tests. Ensure all 4x fans are running to full RPM and
temperature and humidity readings are accurate. If
system fails, contact point of purchase for repair/
replacement.

User/ Owners responsibility: it is required the TMC-500W is tested
regularly as required by applicable regulatory and site standards.
Regular checking of the unit by a qualified person is mandatory to the
safe operation of the unit and the individual components. Powersafe
recommends 3 monthly intervals for inspections. Inspections may be
required more frequently in more adverse operating environments or
under Australian standards or laws.
It is recommended that switchboards are fitted with a breather drain to
allow air flow into the board and for moisture to escape. Inspect
breather drain regularly to ensure debris does not build up around the
drain.
