CHAPTER 4: INSTALLATION SUMMARY
4. INSTALLATION SUMMARY
4.1 Mounting
NOTE: If the UCrypt unit is to be mounted in a rack, it is essential to attach the rear mounting
ears of the unit to rear mounting rails to provide support or alternately install the equipment on a
well supported shelf
Rack mount brackets are provided with the UCrypt device for mounting in a standard EIA 19” rack. Brackets are also provided
for mounting the UCrypt device to a vertical backboard for sites where no rack mounting facilities exist.
4.2 Equipment Safety Grounding
It is imperative that the UCrypt device housing be connected to a permanent building ground in a manner that will ensure that
the exposed metal parts are constantly connected to ground even when the power cord may be disconnected temporarily. A
grounding lug is provided on the rear panel to conveniently effect such a connection. The following guidelines are provided to
clarify the requirements for the installation to meet UL, CUL and CB standards. The use of the words “Ground” and “Earth” as
well as “Grounding” and “Earthing” may be used interchangeably and in this context, have the same meaning.
1. The supplementary equipment grounding conductor is to be installed between the UCrypt device rear panel ground
connector and earth, that is, in addition to the equipment ground conductor in the power supply cord.
2. The supplementary equipment grounding conductor may not be smaller in size than the branch-circuit supply
conductors or a minimum #14 AWG. The supplementary equipment grounding conductor is to be connected at the
rear panel terminal provided, and connected to earth in a manner that will retain the earth connection when the power
supply cord is unplugged. The connection to earth of the supplementary grounding conductor shall be in compliance
with the appropriate rules for terminating bonding jumpers in Part V of Article 250 of the National Electrical Code,
ANSI/NFPA 70, and Section 10 of Part I of the Canadian Electrical Code, Part I, CSA C22.1.
3. Termination of the supplementary equipment grounding conductor may be made to building steel, to a metal electrical
raceway system, or to any grounded item that is permanently and reliably connected to the electrical service
equipment earth.
4. Bare, covered or insulated grounding conductors are acceptable. A covered or insulated grounding conductor shall
have a continuous outer fi nish that is either green, or green with one or more yellow stripes.
4.3 Ambient Environment
The UCrypt device is designed to operate to specifi cation in an ambient room temperature of 0°C to +50°C (+32°F to +122°F)
however it is recommended that it is installed in an environment that approximates normal room temperature to ensure proper
long term operation.
