 Rear Panel Features and Cabling

 Operation

Installation Overview

To install and set up the IPL T CR48, follow these steps:

1. Turn all of the equipment off. Make sure that the input devices (such as motion

detectors and alarms), the IPL T CR48, and the output devices (such as projectors or
screen lifts) are all turned off and disconnected from the power source.

2. Mount the IPL T CR48 unit (see Mounting the IPL T CR48).

3. Attach the cables (see Connecting the Hardware in the “Connection and

Configuration” section.

4. Connect power cords and turn on the devices in the following order: output devices

(projector lifts, screen lifts, lighting system, and so on), IPL T CR48, serial controller or
computer (PC), then input devices (DSS, cable boxes, and so on).

5. Configure the IPL T CR48 through Telnet, then access the unit using an Internet browser.

Mounting the IPL T CR48

Optional rack shelves and an assortment of mounting kits (furniture and projector mount)
are available for use with the IPL T CR48 controller. See the Specifications and Part

Numbers section for the part numbers of these accessories. Read the instructions provided

with the rack shelf or mounting kit for installation procedures.

The IPL T CR48 includes rubber feet so that it can be set on a table. If you are going to
mount the unit to a rack shelf, furniture, or pole, and these feet were attached to the
controller, remove the feet before mounting.

IPL T CR48 • Installation and Operation 3

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of an
IPL T CR48 unit onto a rack.

1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consider installing the equipment in an environment compatible
with the maximum ambient temperature specified by the manufacturer [Tma = +32 to
+122 °F (0 to +50 °C)].

2. Reduced air flow — Installation of the equipment in a rack should be such that the

amount of air flow required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mounting of the equipment in the rack should be such that a

hazardous condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Consideration should be given to the connection of the

equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.

5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment

should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting

For optional rack mounting, mount the unit on an RSF 123 Rack Shelf
(part #60-190-20) (figure 1) or an RSU 129 Universal Rack Shelf (part #60-190-01)
(figure 2).
