Mounting the SCS 300

the SCS 300

The SCS 300 can be mounted on a 1U rack shelf, under or

through a desk, or attached to the projector pole.

UL requirements for rack mounted devices

nted devices

The following Underwriters Laboratories (UL) requirements

pertain to the safe installation of the SCS 300 in a rack.
1

.

Elevated operating ambient temperature

— If installed in

a closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than

room ambient temperature. Therefore, install the SCS in

an environment compatible with the maximum ambient

temperature (Tma = +122 °F, +50 °C) specified by Extron.

2

.

Reduced air flow

— Install the equipment in a rack so that

the amount of air flow required for safe operation of the

equipment is not compromised.

3

.

Mechanical loading

— Mount the equipment in the rack

so that a hazardous condition is not achieved due to

uneven mechanical loading.

4

.

Circuit overloading

— Connect the equipment to

the supply circuit and consider the effect that circuit

overloading 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)

— Maintain reliable

grounding of rack-mounted equipment. Pay particular

attention to supply connections other than direct

connections to the branch circuit (e.g. use of power strips).

Mounting the SCS 300 on a rack shelf

helf

For optional rack mounting, mount the SCS 300 on a standard

9.5" deep Universal or Basic rack shelf (Extron part #60-190-01,

RSU 129,

or #60-604-01, RSB 129) (figure 2-1), or on a 6" deep

Universal or Basic rack shelf (Extron part #60-190-10, RSU 126,

or #60-604-10, RSB 126) (figure 2-2). On the standard 9.5" deep

rack shelf, the SCS 300 can be mounted in one of four locations

at the rear of the rack or the front of the rack shelf:
1

.

If the SCS 300 has feet installed, remove them.

2

.

Align the SCS 300 over the shelf so that the two threaded

holes in the base line up with two holes in the shelf.

3

.

Use two 4-40 x 3/16" screws to mount the SCS 300 to the

shelf.
