7.7 EQUIPMENT TESTING PROCEDURES AND CONNECTION AFTER THE
EQUIPMENT IS INSTALLED.
The same procedure can be used as for the acceptance tests once the system
input and output separation measurements have been taken. When equipment testing is
performed without extracting any module keep in mind that XTM test combs interrupt the
trip signals and close signals only. The rest of the contacts remain connected and can
operate, depending on the test performed To avoid this, the wiring for the related terminals
must be disconnected, making sure that when finished all wires are reconnected properly.
The external connections scheme of figures 3.1, 3.5, and 3.9 shows which logic and analog
inputs pass through the test block (indicated by the sign ><)
8. RECEPTION, HANDLING, AND STORAGE
CAUTION
This relay contains electronic components which could be damaged by
electrostatic discharge currents if those currents flow through certain terminals of
the components. The main source of electrostatic discharge currents is the human
body. Conditions such as low humidity, carpeted floors and isolating shoes are
conducive to the generation of electrostatic discharge currents. Where these
conditions exist, care should be exercised when removing and handling the modules
to make settings on the internal switches. The persons handling the module should
make sure that their body charge has been discharged by touching some surface at
ground potential before touching any of the components on the modules.
This relay is supplied to the customer in a special package, which adequately
protects it during transportation, as long as this is performed under normal conditions.
Immediately after receiving the relay, the customer should check whether it shows
any signs of transportation damage. If it is apparent that the relay has been damaged due
to inappropriate handling, it must be immediately reported in writing to the transportation
carrier, and the damage must be reported to the manufacturer.
For unpacking the relay, care should be taken not to lose the screws also supplied
in the box.
If you do not intend to install the relay immediately, it is recommended that the relay
be stored in its original packaging and kept in a dry, dust-free place.
It is important to check that the data on the name plate coincides with the data from
the order
