further evaluation by Certification Agencies. The following items must be considered.

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
Check nameplate ratings to assure there is no overloading of supply circuits that could have an
effect on overcurrent protection and supply 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.
