1. Introduction

European Regulations

This equipment complies with European Regulations EN 55022 Class A: Limits and Methods of Measurement of Radio Disturbance Characteristics of Information Technology Equipments and EN50082-1: Generic Immunity.

USA Federal Communications Commission (FCC)

This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to part 15 of the FCC rules.

1.1. Safety

All plug-in modules and blank plates are part of the fire enclosure and must only be removed when a replacement can be immediately added. The system must not be run without all modules in place.

Permanently unplug the unit if you think that it has become damaged in any way and before you move it.

•The enclosure can weigh up to 32kg (70.4lb). Do not try to lift it by yourself.

•Do not lift a populated enclosure by the module handles or those on the front of the enclosure, they are not designed to support the weight of the populated enclosure.

•In order to comply with applicable safety, emission and thermal requirements no covers should be removed and all bays must be fitted with plug-in modules.

•The enclosure must only be operated from a power supply input voltage range of 100-120VAC or 200-240VAC.

•The power supply is used as the main disconnect device.

Ensure that the socket outlets are located near the equipment and are easily accessible.

•The equipment is designed to be operated with two working power supply modules.

•To prevent overheating do not operate the enclosure with one power supply removed for more than 30 minutes.

•Disconnect all supply power for complete isolation.

•The power connection should always be disconnected prior to removal of the Power Supply module from the enclosure.

•A safe electrical earth connection must be provided to the power cords. Check the grounding of the enclosure before applying power.

•Provide a suitable power source with electrical overload protection to meet the requirements laid down in the technical specification.

1.2. Rack System Precautions

The following safety requirements must be considered when the unit is mounted in a rack.

•The rack design must incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.

•To avoid the danger of the rack tipping over, do not slide more than one enclosure out at once.

•When loading a rack with the units, fill the rack from the bottom up and empty from the top down.

•The rack design should take into consideration the maximum operating ambient temperature for the unit, which is 40°C.

•The system must be operated with low pressure rear exhaust installation (back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5mm water gauge)).

•The rack must have a safe electrical distribution system.

It must provide over-current protection for the unit and must not be overloaded by the total number of units installed in the rack. Consideration of the electrical power consumption rating shown on the nameplate should be used when addressing these concerns.

•The electrical distribution system must provide a reliable earth for each unit in the rack.

•Each power supply in each unit has an earth leakage current of 1.5mA max at 60Hz, 264VAC per PSU. The design of the electrical distribution system must take into consideration the total earth leakage current from all the power supplies in all the units. The rack may require labelling with “HIGH LEAKAGE CURRENT. Earth connection essential before connecting supply”.

•The rack when configured with the units must meet the safety requirements of UL 60950-1 and IEC 60950-1.
