D8. Install the Device Mounting Plate onto
the Access Door.
To fit the mounting plate and devices on the
access door:
a. Align and slide the device mounting plate onto
the two hinge pins located at the top of the
door frame.
b. Secure the plate into place with
the two mounting plate screws,
located at the bottom of the
door frame.
D9. Cable the Switcher.
a. Connect the cables to the switcher as shown
on pages 43.
CAUTION: The signal transmission method is
specific for PVS 405D switcher working with PVT
digital wallplates. DO NOT connect the input
ports to an MTP, DTP, or XTP system or to an LAN
or data transmission system.
NOTE: For cable connections to optional devices see
the relevant device guide or manual.
b. Plug in the fan controller cable to the switcher
power supply. The fan comes already pre-wired
to the controller in the enclosure.
NOTE: The fan is controlled automatically by the
internal temperature of the PVM 220. The fan can
also be turned on or off manually (see below for
wiring). Manually controlling the fan overrides the
automatic thermal control mode.
The fan can be wired to a control system for manual
On/Off as follows (see figure at right for connectors):
• For manual On, wire a latching relay to the On
and Ground connectors on the fan controller.
• For manual Off, wire a latching relay to the Off
and Ground connectors on the fan controller.
c. Connect and dress the other device cables as
needed, providing enough slack to open and
close the access door.
