Bronson WTI Series
Step-up/Step-down Toroidal Core Voltage Converter
Instruction Manual
c. Switch on the converter
(1) If the voltage converter is connected to a 230 volt power supply via the 230 volt connection,
first switch on the 230 volt circuit breaker. Vice versa, if the voltage converter is connected to a
110 volt power supply via the 110 volt connection, first switch on the 110 volt circuit breaker.
(2) If you connect devices via the screw terminals, you must now also switch on the corresponding
output, i.e. the other circuit breaker. This step is omitted if devices are only connected to the sockets.
(3) Switch on the connected appliances one by one.
3. Caution
a. Always connect converter and connected appliances to ground
You can use your Bronson WTI transformer to connect Class I as well as Class Il appliances.
Class I appliances are electrical appliances that must be connected to the earth by means of a
ground wire. Class Il appliances are double insulated electrical appliance that do not require a
safety connection to electrical earth. Plugs that have a ground connection (e.g. Type B, E, F, G plugs)
are typically used to connect Class I appliances. Always make sure that your connected Class I
appliance are connected to the ground of your converter. Always use an appropriate plug for connecting
your equipment to the converter. If you are using adapters in order to connect other types of plugs,
make sure they have a ground connection.
If you connect devices with an earth connection to the voltage converter via the screw terminals, the
earth connection of the device must be connected to the earth connection of the voltage converter.
Your Bronson WTI converter is a Class I appliance and therefore should only be connected to the electric
grid with a ground connection, regardless of the devices you connect to your converter.
b. Avoid Overloading
Do not connect to any appliance whose total wattage rating is beyond the maximum power rating of
the converter (or to multiple appliances whose combined wattage ratings are greater than the maximum
converter rating.)
Make sure that the total starting power of all connected appliances does not exceed the listed
maximum output power of the converter. When connected to an appliance with a built-in motor
compressor, the starting power is generally several times that of the appliance's listed power rating.
For colour TVs, calculate twice the listed capacity.
Devices that can generate internal induction voltage or static charge should not be used with a WTI
transformer.
