Important Safety Instructions
CAUTION! To reduce the risk of electric shock and re, do not remove the cover of this device. There are no
user serviceable parts inside. Please refer all servicing to licensed service technicians.
CAUTION! The international symbol of a lightning bolt inside a triangle is intended to alert the user to
uninsulated “dangerous voltage” within the device’s enclosure. The international symbol of an exclamation
point inside a triangle is intended to alert the user to the presence of important operating, maintenance and
servicing information in the manual accompanying the device.
CAUTION! To prevent electrical shock, match wide blade of plug to wide slot, fully insert.
CAUTION! To reduce the risk of electrical shock, do not expose this equipment to rain or moisture.
1. Read Instructions—All safety and operating instructions should
be read before operating the device.
2. Retain Instructions—The safety and operating instructions
should be retained for future reference.
3. Heed Warnings—All warnings on the device and in the
operating instructions should be adhered to.
4. Follow Instructions—All operating and safety instructions
should be followed.
5. Water & Moisture—The device should never be used in, on or
near water for risk of fatal shock.
6. Ventilation—The device should always be located in such a
way that it maintains proper ventilation. It should never be
placed in a built-in installation or anywhere that may impede the
ow of air through its ventilation slots.
7. Heat—Never locate the device near heat sources such as
radiators, oor registers, stoves or other heat-generating
devices.
8. Power Cord Protection—Power cables should be routed so they
are not likely to be stepped on or crushed by items placed on
them or against them. Special attention should be paid to areas
where the plug enters a socket or fused strip and where the cord
exits the device.
9. Periods Of Non-Use—The device should be unplugged when
not being used for extended periods.
10. Dangerous Entry—Care should be taken that no foreign
objects or liquids fall or are spilled inside the device.
11. Service—The device should always be serviced by
licensed technicians. Only replacement parts specied by
the manufacturer should be used. The use of unauthorized
substitutions may result in re, shock, or other hazards.
12. Damage Requiring Service—The device should be serviced by
licensed technicians when:
• The plug or power supply cord has been damaged.
• Objects have fallen or liquid has spilled inside the device.
• The device has been exposed to moisture.
• The device does not appear to be operating properly or exhibits
a marked change in performance.
• The device has been dropped or the enclosure becomes
damaged.
13. Do not position the equipment so that it is difcult to operate
the disconnecting device (power cord).
14. If the equipment is used in a manner not specied by the
manufacturer, the protection provided by the equipment may be
impaired.
15. The power switch should be in the “off” position when
connecting or disconnecting equipment from a Torus Power unit.
16. CAUTION Some units can be very heavy, please use safe
practices when lifting.
Please keep the original shipping box and all packing material.
This will ensure the unit is protected in future transport.
In the unlikely event you have a problem and must return it for
service you must use the original packing material.
Ship the unit only in the original packing material, as the unit is
not insurable by carriers otherwise.
Shipping Carton & Packing Material
Torus power PIUs (Power Isolation Units) are extremely efcient
yet very high power devices, and must be adequately cooled.
Wall Mount units have ventilation slots on the side panels near
the top of the unit. Maintain at least 5” distance from each of
these surfaces to anything else.
Do not install the unit directly above heat generating equipment.

Torus Power WM Series Description
The input fuses prevent excessive current from
entering the PIU.
Circuit Protection Thermal Protection
The Torus Power PIU will shut down if internal
unit temperature reached excessive levels.
Transient Voltage Surge Suppression (TVSS)
All WM Series models are available with a Transient Voltage Surge Suppression (TVSS) device
built into its signal path. The UL certied panel TVSS responds in under 5 nano-seconds and
manages surges up to 80,000 Amps. The TVSS also offers additional noise ltration of EMI and
RFI (40 dB typical).
Torus Power PIUs (Power Isolation Units) combine the best surge suppression with unique
toroidal transformer technologies from PLITRON to provide the ultimate performance and
protection for sensitive audio and video equipment applications.
Balanced input power from two 120V phases provides high input power and noise cancellation.
Using balanced input power provides the benets of symmetrical power without the requirement
to use GFCI (ground fault circuit interruption) outlets. GFCIs are prone to nuisance trips. The
toroidal isolation transformer steps down the 240V input to 120V to power equipment. (Where
240V balanced input is unavailable, units may be congured for 208V operation.)
PIUs use ZeroSurge patented series-mode surge removal lters to absorb dangerous voltage
surges and safely dissipate them without using failure prone MOVs (metal oxide varistors). Also,
unlike MOV based protection, voltage surges are not shunted to ground.
Isolation is combined with proven proprietary technologies from PLITRON in the oversized
toroidal transformer. NBT works as a low pass lter using the controlled leakage inductance
and capacitances within the transformer to cancel common mode and differential mode noise.
LoNo technology has been used for years by high end audio companies who demand silent
transformers. Imin technology reduces inrush currents. UST provides additional common mode
ltering using a highly efcient Faraday screen.
Low-impedance output with balanced high power primary input provides the most unconstrained,
yet protected, energy source available to your equipment.
Power Sharing Outputs
Each output circuit breaker protects an individual circuit. However, all circuits share a single
winding (output) on the isolation transformer. This “Power-Sharing” allows huge excursions of
current, up to and beyond the full power of the unit, to be available at any individual circuit, for
instantaneous bursts of power.
