4 U X 8 8 0 0 I N S TA L L AT I O N4 . 1 P h y s i c a l I n s t a l l a t i o nCAUTION: The UX8800’s operating temperature range is 32 F to 104 F degrees / 0 C to 40C degrees. The UX8800 may not function properly in temperatures below this range and maybe damaged in temperatures above this range.4.1.1 MOUNTINGThe UX8800 is designed to mount in a standard, 19 in equipment rack occupying one EIA rack space (1.75in). When rack mounting, use screws with mating plastic washers to help protect the finish of the UX8800.The UX8800 weighs approximately 10 lb / 4.5 kg.4.1.2 VENTILATIONAn integral fan is used to properly ventilate theUX8800. The fan is located to the rear of the leftside of the chassis. The air intake grilles are locatedon the right side and on top of the chassis. Maintainclearances around the left and right sides of thechassis as shown in the drawing.It is recommended to leave one empty rack spaceabove the UX8800 to provide 1.75 in / 45 mmclearance above the top air intake holes foradditional ventilation.4 . 2 A C M a i n s C o n n e c t i o n s4.2.1 AC MAINS VOLTAGEThe UX8800 has a universal, auto-ranging power supply that operates from 100 V to 240 V, 50 Hz to 60 Hz.The UX8800 is compatible with these nominal ac mains:100 V, 110 V, 115 V, 120 V, 127 V, 220 V, 230 V, and 240 V at 50 Hz to 60 Hz.CAUTION: To maintain compliance ratings, keep the ac mains voltage between 100 V to 240 V.4.2.2 IEC POWER CORD RECEPTACLEAn IEC-320 ac mains inlet on the rear panel accepts the detachable power cords supplied with the unit. Usethe power cord appropriate for these nominal ac mains supply voltages.120 V ac mains: use the power cord with the NEMA 5-15 plug, EAW part # 640-01-00220 V ac mains: use the power cord with the Schuko plug, EAW part # 640-02-02CAUTION: It is the user’s responsibility to provide a proper ac mains plug for anyac mains outlet configuration that differs from those supplied with the product.4.2.3 GROUNDINGThe chassis of this product is grounded through the grounding conductor of the power cord. To avoidelectric shock, plug the power cord into a properly wired and grounded receptacle before making anyconnections to or operating the product.DANGER: This equipment must be operated with the power cord grounding conductorconnected to a properly grounded ac outlet. Do not disconnect, “lift,” or otherwise remove thisground connection. Without this connection, accessible parts, including knobs and controlsthat may appear to be insulated, can render an electric shock that can cause injury or death tooperating personnel.Page 5MAINTAIN 1 in / 25 mmCLEARANCE AROUNDSIDE AIR INTAKE GRILLESRECOMMENDED:MAINTAIN 1-3/4 in / 45 mm CLEARANCEABOVE TOP AIR INTAKE GRILLESMAINTAIN 2 in / 50 mmCLEARANCE AROUNDFAN EXHAUST GRILLEAIR FLOWVENTILATION CLEARANCESPOWER~100-240 VAC50-60Hz 75W
