Sierra Video Yosemite - Manual (Page 9)

INTRODUCTION

 Only an authorized Sierra video technician should service the
switchers. Any user who makes changes or modifications to the unit
without the expressed approval of Sierra video will void the
warranty.
 If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than the
room ambient temperature. Therefore, consideration should be given
to installing the equipment in an environment compatible with the
manufacturer’s maximum rated ambient temperature (TMRA).
 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.
Power Supply Cords
Use only power cord(s) supplied with the unit.
If power cord(s) were not supplied with the unit, select as follows:
 For units installed in the USA and Canada: select a flexible, three-conductor
power cord that is UL listed and CSA certified, with individual conductor wire size
of #18 AWG, and a maximum length of 4.5 meters. The power cord terminations
should be NEMA Type 5-15P (three-prong earthing) at one end and IEC
appliance inlet coupler at the other end. Any of the following types of power cords
are acceptable; SV, SVE, SVO, SVT, SVTO, SVTOO, S, SE, SO, SOO, ST,
STO, STOO, SJ, SJE, SJO, SJOO, SJT, SJTOO, SP-3, G, W.
 For units installed in all other countries; select only a flexible, three-conductor
power cord, approved by the cognizant safety organization of your country. The
power cord must be Type HAR (Harmonized), with individual conductor wire size
of 0.75 mm². The power cord terminations should be a suitably rated earthing-
type plug at one end and IEC appliance inlet coupler at the other end. Both of the
power cord terminations must carry the certification label (mark) of the cognizant
safety organization of your country.
North American Power Supply Cords
This equipment is supplied with North American power cords with molded grounded plug (NEMA-
15P) at one end and molded grounding connector (IEC 320-C13) at the other end. Conductors
are CEE color coded, light blue (neutral), brown (line), and green/yellow (ground). Operation of
the equipment at voltages exceeding 130VAC will require power supply cords that comply with
NEMA configurations.
International Power Supply Cords
If shipped outside North America, this equipment is supplied with molded ground connector (IEC
320-C13) at one end and stripped connectors (50/5mm) at the other end. Connections are CEE
color coded, light blue (neutral), brown (line), and green/yellow (ground). Other IEC 320-C13 type
power cords can be used if they comply with safety regulations of the country in which they are
installed.
