Appendix B Safety and Regulatory Compliance
Information
Choose a site with a dry, clean, well-ventilated and air-conditioned area.

Choose a site that maintains an ambient temperature of 32 to 104

2. Creating a Safe Environment
Connect AC-powered systems to grounded power outlets or as per local regulations.

Do not move or ship equipment unless it is correctly packed in its original wrapping and

shipping containers.
Only allow Harmonic trained personnel to undertake equipment service and

maintenance. Do not permit unqualified personnel to operate the unit.
Wear ear protection when working near an NSG Pro platform for a longer period of time.

3. Rack Mounting the Unit
Install the system in an open rack whenever possible. If installation in an enclosed rack is

unavoidable, ensure that the rack has adequate ventilation.
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). This unit should be mounted at the bottom of the rack if it is the
only unit in the rack.
When mounting this unit in the partially filled rack, load the rack from the bottom to the

top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or

servicing the unit in the rack.
The rack must be anchored to an immovable support to prevent it from tipping when the

unit is mounted on it. The rack must be installed accoring to the rack maufacturer's
instructions.
Disconnect all power and external cables before lifting the unit. Depending on the weight

of the unit, more than one person might be required to lift it.

Adding to the system a UPS (Uninterrupted Power Supply) and an AVR (Automated
Voltage Regulator) is highly recommended.
Installing the main power supply by a qualified electrician, according to power
authority regulations. Make sure all powering are wired with an earth leakage,
according to local regulations.
It is recommended to install the encoder within 1.5m (approximately 5 feet) from an
easily accessible grounded AC outlet.
When the encoder is rack-mounted, ensure that the rack is correctly grounded.
Ensure a suitable overcurrent device is in-line between the equipment and the power
source.
Connect DC-input power supplies only to a DC power source that complies with the
safety extra-low voltage (SELV) requirements in the UL60950-1, CAN/CSA-C22.2
No. 60950-1-03, AS/NZS 60950-1, EN/IEC 60825-1, 21 CFR 1040, EN 60950-1,
and IEC 60950-1 standards.
Ensure that power is removed from the DC circuit before installing or removing
power supplies
