Warnings and Cautions:
INSTALLATION INSTRUCTIONS
Secure Racking
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.
Input Supply
1. Check nameplate ratings to assure there is no overloading of supply
circuits that could have an effect on overcurrent protection and supply
wiring.
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.
Grounding
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.
