2.3. POWER REQUIREMENTS
2.3.1. Selecting the Correct Mains Voltage
The VITS Inserter has one or two universal power supplies that automatically sense the input voltage.
(Redundant supply is optional) The 9531 operates on either 115 Volt / 60 Hz or 230 Volt / 50 Hz AC. The
PSU STATUS LEDs on the front panel indicate if the power supplies are operating normally.
Power should be applied by connecting a 3-wire grounding type power supply cord to the power entry
modules on the rear panel. The power cord should be minimum 18 AWG wire size; type SVT marked VW-
1, maximum 2.5 m in length. The power entry module combines a standard power inlet connector, two 5 x
20 mm fuse holders and an EMI line filter.
2.3.2. Changing the Fuse
The fuse holder is located inside the power entry module. To change the fuses, pull out the fuse holder
from the power entry module using a small screwdriver. The fuse holder contains two fuses, one for the
line and one for the neutral side of the mains connection. Pull out the blown fuse and place a fuse of the
correct value in its place. Use slo blo (time delay) 5 x 20 mm fuses rated for 250 Volts with a current
rating of 1 amp. Carefully reinsert the fuseholder into the power entry module.
!Never replace with a fuse of greater value.
2.4. CONNECTING THE DIGITAL VIDEO
The 9351 VITS Inserter can have up to 3 independent processing units installed. Each unit operates
