2.10 PS70V Setting Line Voltage
The PS70V Power Supply has an AC Line Select Switch that allows you
to select the required line voltage range. This switch is accessed by re-
moving the plug-in power supply from the switcher, if the power supply is
already installed. Be sure to disconnect the AC power cord before remov-
ing the power supply from the switcher. A separate jumper, located under
the plastic safety cover surrounding the switch is used to add 15 volts to
each switch setting. Using only the switch, the nominal (± 10%) input AC
line voltages available are 100, 120, 140, 200, 220, and 240. If the jumper
is also moved, these voltages become 115, 135, 155, 215, 235, and 255.
Be sure the AC Line Select Switch and jumper are set to the correct
positions before powering up the video routing switcher.
Access is provided to the jumper by removing the two screws that secure
the cover. These screws also secure the PC board to the mounting tray.
Be sure to replace both screws. Tighten securely but avoid cracking the
plastic cover.
2.11 PS70V Power Supply Installation
The PS70V Power Supply(s) are installed in the upper right-hand portion
of the Cougar Video Routing Switcher. The Cougar Video Routing
Switcher is designed for the installation of up to two PS70V Power Sup-
plies. If only one PS70V Power Supply is to be installed in the Cougar
Video Routing Switcher, install it in the left-hand position.
To install the PS70V Power Supply or to install the PS70V Power Supplies
in the Cougar Video Routing Switcher take the following steps while refer-
ring to the Cougar Video Mainframe configuration drawing on page 6.2:
1. Align the primary power supply with the left-hand set of circuit card
guides in the upper right-hand side of the Cougar Video Routing
Switcher.
2. Carefully push the power supply into the switcher until the power
supply connector makes initial contact with backplane power connec-
tor. At this point, firmly but carefully continue pushing the power supply
into the switcher while making sure the connectors are properly
aligned. Continue pushing the power supply until it is in place and the
connectors are firmly mated.
