manufacturers must provide protection to service personnel against inadvertent contact with these module output terminals.
If set such, that hazardous energy can occur, then the module terminals or connections must not be user accessible.
Disconnect device: An appropriate disconnect device shall be incorporated in the building installation wiring. Refer to the
user manual of the specific model for more details.
Rack mounting safety instructions:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - 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.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved
due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the
effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration
of equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - 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).
