DEFINITIONS Table 1: Definitions Term Definition A Cassette is the unit that is installed within Outlet Cassette System (OCS) or Fixed Cassette System (FCS). There are two types: FCS Cassettes and OCS Cassettes. Cassette Each Cassette houses a Protection Element, phase current transformers and main contactor components.
1.1.5 Operation As safety depends on the OCS functioning correctly it is highly recommended that all safety functions of the OCS be periodically tested to ensure correct operation.

Equipment that is found to be damaged or has been modified away from its published specification must not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or if it does not match the published specifications.
This has the advantage of resulting in minimal down-time in the event of a fault. The Ampcontrol OCS is available in two types: the standard OCS and the Fixed Cassette System (FCS). The OCS provides isolation and earthing of individual outlets via integrated actuators that are controlled at the touch of a button via a Human Machine Interface (HMI) screen.
MAG-182 Version 5 – FEB/2020 The FCS (1.1kV systems only) sacrifices the remote isolation and earthing functionality of the OCS to provide a higher outlet density. Due to the compact nature of the FCS, 10 outlets are able to be installed in the same area used by a conventional 8 outlet system.

If modifications of any form are made to the OCS, the equipment may no longer be fit for purpose. If any modifications or damage to the OCS is evident, do not use the equipment and contact Ampcontrol for advice.
4.3 Mechanical Arrangement 4.3.1 OCS Dimensions The OCS is available in two sizes: the 2-Way OCS and the 3-Way OCS. These modules are designed to be stacked on top of each other, allowing the best utilisation of the installation area.
The FCS has a very high outlet density, allowing more outlets to be installed with a smaller footprint. 1160 Figure 4.3: FCS Dimensions (Pictured with 5 Cassettes Installed) 4.4 Electrical Installation Information Refer to drawing OCSE002in APPENDIX B: DRAWINGS for electrical installation information.

4.5 External Accessories 4.5.1 Earth Leakage CT The Outlet Cassette Protection Element uses an Ampcontrol EL500 series current transformer for earth leakage measurements. For the purposes of outlet identification tests during operation, the earth leakage toroid is installed separately to the Cassette.
If the Earth Fault Lockout and Earth Continuity tests are successful, check that an automatic HV insulation test is initiated by the Cassette Protection Element when the module is started. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 19 of 72...
NOTE A Main Contactor Fail (MCF) trip can be reset by pressing the MCF Reset Pushbutton on the front of the OCS Protection Element or through the communications protocol. While the Cassette Protection Element is stopped, close the MCI digital input. Ensure that a CBR trip is initiated by the Cassette Protection Element.

The time and date are not used for any control functions. 6.7 Cassette Isolation & Earthing (OCS Only) Through the use of remotely controlled actuators, the OCS allows individual Outlet Cassettes to be moved between the service and earth positions. This provides both a break between the outlet phase conductors and the incoming supply, as well as visual earthing of the outlet cable without the requirement of a separate earthing outlet.

Earth Leakage current displayed as 0-150% of selected trip level 7.1.2 Operation Summary The earth leakage protection function uses an Ampcontrol EL500 series toroid to measure the earth fault current. This function is tested to AS/NZS 2081:2011. A definite time operating characteristic is provided with adjustable trip sensitivity and an adjustable time delay.

The Protection Element can be configured to operate in either diode or RTX mode. This determines what terminating device the relay is expecting on the pilot. NOTE The RTX will only be recognised by an OCS Protection Element and will not be seen as a diode by other earth continuity devices. CAUTION! Cable parameters are important to the correct operation of the Pilot E/C function.

A number of external system based checks should be completed on a regular basis. These ‘routine inspections’ must be carried out by suitably trained people with knowledge of the OCS and the systems into which it is fitted. Routine inspections may take the form of either visual-only checks, or visual and ‘hands-on’...
Cassette can seriously compromise the safety of the unit and voids product warranty. It is recommended that the electrical protection system incorporating the OCS be subject to regular functional tests at intervals determined by risk assessment or FMEA. These intervals typically coincide with periodic maintenance checks and will cover (but not limited to) tests such as: ...
