Wire Temperature Rating
The supply wiring to the power supply terminal blocks must have a minimum temperature rating of
75ºC.
mu
Circuit Protection
The building installation must provide overcurrent and short circuit protection in the non earthed supply
conductor.
-48V DC PSU: USA and Canadian Safety Requirements
Wiring Methods
Wiring method must be code compliant in the field.
Wiring methods must be in accordance with the U.S. National Electric Code, Article 300.
Earthing
This equipment is designed to permit the connection of the earthed conductor (+) of the DC supply circuit
to the earthing conductor at the equipment.
Protective Earth Conductor Size
The protective earth conductor size must be suitable for the maximum fault current that the installation
can provide. U.S. National Electric Code, Article 250-122
Branch Circuit Protection
The PSU must be connected to a Branch circuit that is protected by a LISTED Branch Protector. The
rating of the LISTED Branch Protector >= 125% of the product rating and the rating of the LISTED Branch
Protector =< current rating of wire supplying the equipment. U.S. National Electric Code, Article 210-3,
Article 240.
Rack System Precautions
The following safety requirements must be considered when the unit is mounted in a rack.
• The rack design should incorporate stabilizing features suitable to prevent the rack from tipping or
being pushed over during installation or in normal use.
• When loading a rack with the units, fill the rack from the bottom up and empty from the top down.
• 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 design should take into consideration the maximum operating ambient temperature for the
unit, which is 35°C with a single Power Supply/Cooling module fitted and 40°C when dual Power
Supply/Cooling modules are fitted.
• The rack should have a safe electrical distribution system. It must provide overcurrent protection for
the unit and must not be overloaded by the total number of units installed in the rack. Consideration
of the units nameplate rating should be used when addressing these concerns.
• The electrical distribution system must provide a reliable earth for each unit and the rack.
