CStripping the wires to expose less than the recommended amount may cause them to slide out of the connector too easily, even if they are tightly pinched by the captive screws.

CDo not tin the stripped power supply leads before attaching the captive screw plug to them. Tinned wires are not as secure in the captive screw connectors and can be easily pulled out. They may also break after being bent several times.

3.	Slide the leads into the supplied 2-pin captive screw plug
	and secure them, using an Extron Tweeker or other small
	screwdriver.
4.	Use the supplied tie wrap to strap the power cord to the
	extended tail of the connector.

Rack mounting

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the PS 123 into a rack.

•Elevated operating ambient temperature — If the equipment is installed in a closed or multiunit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature.

Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. For the PS 123, the Tma is 122 °F (50 °C).

•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.

•Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not created due to uneven mechanical loading.

•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.

•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 (e.g. use of power strips.

Rack mounting procedure

For optional rack mounting, mount up to four PS 123s on an RSU 129 9.5" 1U Universal Rack Shelf (part #60-190-01) (figure 8) or an RSB 129 9.5" 1U Basic Rack Shelf (part

#60-604-01).
