Disconnect Device

The AC mains plug is used as the disconnect device.

The disconnect device must remain readily operable.

Rack-mount Considerations

A. Elevated Operating Ambient

If installed in a closed or multi-unit rack assembly, the operating ambient tempera- ture 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 maxi- mum ambient temperature (Tma) specified by the manufacturer (see “Specifications” infor- mation in this document).

B. 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. Do NOT stack other equipment on the top of the PCS100R unit.

C. Circuit Overloading

Consideration should be given to the con- nection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.

D. Reliable Earthing

Maintain reliable earthing of rack-mounted equipment. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

E.Mains Outlet Earthing

The apparatus with Class I construction must be connected to a mains socket outlet with a protective earthing connection.
