Installing your VCCS300 Product
The VCCS300 power supply is designed to be used as part of an end-system in a restricted environment and therefore should only be accessible to qualified and
trained personnel. Persons attempting to install a unit must have the necessary knowledge and training before doing so. Incorrect installation may cause damage to
the power supply and may affect the warranty.
DO NOT use parts if any part of the product exhibits any kind of physical damage.
DO NOT connect any mains power before the installation is complete.
Once installation has been completed, operation of the unit should be verified.
Please contact Vox Power or your distributor for assistance in installing your power supply. Never assume, always ask.
Connecting units in series
VCCS300 units of the same type can be series connected to achieve higher output voltages. Below is an illustration of how-to series connect three units to give 900W
of output power.
When mounting multiple units ensure to maintain sufficient safety clearances between units. See installation clearances section for more details.
Isolation to Ground
Care must be taken not to exceed the output isolation to chassis ground when series connecting units. Each output is rated for 2200 Volts maximum between each
output terminal and chassis ground. Exceeding this voltage may damage the unit.
SELV Precautions
Where series combinations of units exceed 60V, the output can no longer be considered SELV (Safety Extra Low Voltage) and hence the final equipment manufacturer
must provide suitable protection for both users and service personnel.
Ripple
When outputs are series connected, the output ripple will increase and may contain frequencies in the audio spectrum.
WARNING!
•
Energy and voltage hazards may arise when individual units are series connected. When safe energy and voltage levels are exceeded ensure that
an appropriate warning label is affixed to the power supply in a manner that service personnel will always notice it. See the Safety section for
more details.
•
Leakage currents will increase when multiple units are installed in an end-system.
