Rack mounting instructions

Note that rack mounting is not mandatory for the unit. When the unit is mounted in a 19” rack ensure that the following instructions are observed:

•The unit is supported at the rear;

•If installed in a closed or multi-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 (Tmax) specified;

•Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipement is not compromised;

•Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading;

•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;
