Warnings and Cautions:
If Secure Racked units are installed in a closed or multi-unit rack assembly,
they may require further evaluation by Certification Agencies. The
following items must be considered.
1. The ambient within the rack may be greater than room ambient.
Installation should be such that the amount of air flow required for
safe operation is not compromised. The maximum temperature for the
equipment in this environment is 45°C. Consideration should be given
to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not
achieved due to uneven loading.
1. Check nameplate ratings to assure there is no overloading of supply
circuits that could have an effect on overcurrent protection and supply
2. When installing 48 VDC rated equipment, it must be installed only per
the following conditions:
A. Connect the equipment to a 48 VDC supply source that is
electrically isolated from the alternating current source. The 48
VDC source is to be connected to a 48 VDC SELV source.
B. Input wiring to terminal block must be routed and secured in such
a manner that it is protected from damage and stress. Do not
route wiring past sharp edges or moving parts.
C. A readily accessible disconnect device, with a 3 mm minimum
contact gap, shall be incorporated in the fixed wiring.
Reliable earthing of this equipment must be maintained. Particular
attention should be given to supply connections when connecting to power
strips, rather than direct connections to the branch circuit.
