Power Supply Transformer Requirements Sites in the United States of America, Canada, Japan, and other countries that require the use of a transformer (step-up or step-down), must ensure that the transformer meets local and national authority electrical regulations. For example, in North America the transformer must be of the Listed Type.

If not reduced, these microsecond pulses can disrupt system operation. • Voltage transients must be tested when all machinery and air-conditioning equipment are operating normally and the FB10000 system is turned on. Voltage spikes should not exceed +5 or -10%. • All potential noise-generating equipment (e.g. fans, fluorescent lighting and airconditioning systems) must be kept separate from the power source used for the FB10000 press. 36 HP Scitex FB10000 Site Preparation Guide, Rev. 2
