3 PRODUCT OVERVIEW
The Ampcontrol Outlet Cassette System (OCS) is a major advancement in control and protection
technology. The OCS combines the outlet contactor, protection element, current transformers and outlet
test circuitry into a single replaceable unit. 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. In this manner, operators are not
exposed to potential electric shocks resulting from residual static charge on the cable. This also
eliminates a potential ignition source of an explosive atmosphere.

Page 12 of 72
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. The FCS is designed as a fully bolted, non-
withdrawable installation, whilst still minimising downtime by providing fast and easy removal of the
cassette protection components.

4 INSTALLATION
4.1 General Warnings
These instructions have been designed to assist users of the OCS with installation.
Before the OCS can be installed, there are a number of things that need to be considered and
understood to prevent incorrect or unsafe operation of the OCS or the system into which it is installed.
Along with relevant competence, and an understanding of the target application, the following points
should be considered:
4.1.1 Ensure that the information provided in this user manual is fully understood.
It is extremely important that the limitations and functionality of the OCS are understood to prevent
incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the nature of
the limitations or their implication, refer to the installation’s safety dossier or consult a competent
authority such as a supervisor or Ampcontrol technical representative.
4.1.2 Ensure that the application into which the OCS is being installed has been
properly defined, designed and approved.
Any system intended to mitigate the risk of injury needs to be properly designed and implemented.
Such a system must be the result of structured risk analysis with the outcomes used to define the
system requirements. These requirements, in turn, will guide the choice of instrumentation, logic
solvers and actuators needed to implement the system. Understanding the needs of the system will
ensure proper selection of equipment.
4.1.3 Ensure that the OCS will properly perform the required functions within the
system design.
It is important to understand how the OCS is intended to interact with other equipment within a system.
For safe and reliable use, it is crucial that neither the OCS’s logical operation nor its signalling be
compromised by incompatibilities with connected equipment.
4.1.4 Modifications of any form to the OCS are prohibited.
The OCS as supplied has been designed and manufactured to comply with the requirements of
protection standards. 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.

4.5 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.
4.5.2 Remote Termination Unit (RTX)
The RTX is a microprocessor based module that can be utilised to replace the diode at the end of the
trailing cable pilot conductor. It is powered by and communicates via the pilot line. Its non-volatile
memory stores the parameters to configure the outlet as appropriate for the connected machine. The
RTX Module is pictured in Figure 4.4.
All terminals are fully shrouded, with the pilot and earth terminals being segregated from the other
terminals.
The RTX provides remote start and stop facilities. The circuitry involved in these functions is self-
diagnostic and will cause the outlet to turn off if the circuits are earthed or interconnected. This reduces
the chance of the outlet operating when not required to do so due to wiring faults. It should be noted
that these functions are operational only, and that any emergency stops should be wired directly into
the pilot circuit.
PTC terminals are provided for a semiconductor ‘switching’ thermistor. These terminals are protected in
a similar manner to the stop and start circuits. If the remote start, stop and PTC functions are not
required, each set of terminals must be bridged in order to start the Protection Element.
Five RTD inputs are provided for PT100 RTDs. These terminals can also be used with resistor
networks to provide digital information back to the Cassette Protection Element.
A parameter dongle allows an RTX to be replaced without needing to re-program the parameters.
When installed, this dongle should be firmly secured to the machine/equipment.
Figure 4.4: Remote Termination Unit (RTX)
4.5.3 Parameter Dongle
Parameters important to the running of the Protection Element and the safe operation of the outlet onto
which it is connected are stored in the Protection Element Parameter Dongle. The Parameter Dongle is
exchangeable between Protection Elements, but it is intended to be physically tethered to the outlet
that it controls.
Although the Protection Element and the RTX use the same hardware parameter dongle the
parameters they store are different. As such the parameter dongle is not interchangeable between the
Protection Element and RTX.

5 COMMISSIONING AND CALIBRATION
Prior to being put into service, the electrical protection system must be correctly commissioned. This
manual does not cover system commissioning; the full scope of commissioning tests should be
determined during the risk assessment or FMEA covering the design of the electrical protection system.
The following test can provide guidance on checking the correct operation of the Cassette Protection
Element during commissioning. These tests should be performed on each individual Cassette within the
installed OCS.
This is not intended to provide an exhaustive commissioning checklist, but should be considered to be a
minimum set of tests.
5.1 Earth Leakage
Test the correct operation of earth leakage circuits by injecting a fault current through the Earth Leakage
CT. Ensure that all relevant tripping circuits operate successfully and that latched trips may be reset in
the appropriate manner.
Disconnect the toroid from the Cassette Protection Element and ensure that an EL CT fault trip is issued
with similar effect.
5.2 Residual Voltage
This is applicable to the Residual Voltage Protection Element Version only. Test the correct operation of
residual voltage detection circuitry by injecting a residual voltage onto the phases. Ensure that all
relevant tripping circuits operate successfully and that latched trips may be reset in the appropriate
manner.
These tests can be facilitated using residual voltage test relays, built into the Cassette Protection
Element. These relays are controlled using the Cassette Protection Element’s communications interface.
5.3 Earth Fault Lockout
Test the correct operation of Earth Fault Lockout protection by connecting suitably rated test resistors to
the power conductors. Attempt to energise the outlet and confirm that the Cassette Protection Element
trips on Earth Fault Lockout.
WARNING!
If the Earth Fault Lockout does not trip during this test, full system
voltage and power may be subsequently applied to the test
resistors.
5.4 Earth Continuity
Test that the Earth Continuity protection is operational by creating an open circuit on the pilot conductor.
Ensure that all relevant tripping circuits operate successfully and that latched trips may be reset in the
appropriate manner.
Repeat with a short circuit between pilot and earth.
These tests can be facilitated using earth continuity test relays, built into the Cassette Protection
Element. These relays are controlled using the Cassette Protection Element’s communications interface.
5.5 Insulation Test (High Voltage)
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.

Page 20 of 72
WARNING!
During this test the Cassette Protection Element will generate up to
2700VDC from the 24 VDC input supply and apply this voltage to the
phase conductors.
5.6 Over Current/Motor Overload Current Injection
Test the Over Current/Motor Overload protection by carrying out secondary/primary injection on the CT
inputs of the Cassette Protection Element.
Inject 2x Full Load Current (FLC) into one of the CT terminals and ensure that all relevant tripping
circuits operate successfully, in the time expected according to the settings employed, and that latched
trips may be reset in the appropriate manner. Repeat on the other CT terminals.
5.7 Short Circuit Current Injection
Test the Short Circuit protection by carrying out secondary/primary injection on the CT inputs of the
Cassette Protection Element.
Inject a current value relevant to the settings employed into one of the CT terminals and ensure that all
relevant tripping circuits operate successfully, in the time expected, and that latched trips may be reset in
the appropriate manner. Repeat on the other CT terminals.
5.8 Main Contactor Fail
While the Cassette Protection Element is stopped (that is, the MCR output is open), apply a voltage on
the load side of the contactor. The voltage must be greater than the selected trip level. Ensure that a
