Note: Check if the DC mains source voltage (-36 - -58 V dc) corresponds to the
appropriate power input voltage for the unit. This voltage is noted on the back of the
chassis.
WARNING:
Pay attention to the DC power source connection, wrong polarizing the DC
power source may result in damage to the PSU module.
CAUTIONS:
When a Continuum DVP XDQA component is brought from a cold into a warm
environment, the component should be acclimated to the environment
temperature and humidity conditions for at least 30 minutes. Non-acclimated
components may not meet the technical specifications as described.
Powering up a non-acclimated component may result in damage to the
component and/or chassis.
