Electrical Safety requirements:
1. This product is to be installed Only in Restricted Access Areas
(Dedicated Equipment Rooms, Electrical Closets, or the like).
2. DC products shall be installed with a readily accessible disconnect device in
the building installation supply circuit to the product.
3. This product shall be provided with a maximum 10A DC Listed fuse or circuit
breaker in the supply circuit when connected to a DC centralized source.
4. The external power supply for DC units shall be Listed, Direct Plug In power
unit, marked Class 2, or listed ITE Power Supply, marked LPS, which has
suitably rated output voltage (i.e. 24VDC or 48VDC) and suitable rated output
current.
5. Use minimum 18 AWG size wiring for connection to a Centralized DC power
source.
6. For earthing wiring, use minimum 14 AWG size wiring.
7. Product does not contain user replaceable fuses. Any internal fuses can ONLY
be replaced by GarrettCom personnel through the RMA process.
Installation requirements:
1. Elevated Operating Ambient Temperature- If installed in a closed or multi-unit
rack assembly, the operation 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 manufacturer’s
maximum rated ambient temperature (Tmra).
2. 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.
3. Mechanical Loading – Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading – consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might
have on over current protection and supply wiring. Appropriate consideration
of equipment nameplate ratings should be used when addressing this concern.
5. Reliable Earthing – Reliable earthing of rack mounted equipment should be
maintained. Particular attention should be given to supply connection other
than direction connections to the branch circuit (i.e. use of power strip etc…)
