WARNING
Death or severe injury caused by high voltage possible
The terminal adapters have blank ends.
► Before connecting the terminal adapters, press the Emergency stop button on the
COMPANO's front panel and secure the test set against reactivation (→ Wiring and
Safe Connection on page 9).
► Always insert the terminal adapter with its blank end first into the terminal strip, and
fasten it before connecting it to a test lead.
3.4.3 Grounding COMPANO 100
In a substation environment, do not operate COMPANO 100 without an additional connection to
ground. That connection should have a diameter of at least 2.5 mm
2
(→ side view on page 18).
Ground COMPANO 100 as close as possible to the operator.
COMPANO 100 is of protection class II. Therefore, grounding is not as critical as with devices that are
grounded via a power cord. Nevertheless, due to internal capacities you could still sense some
coupled voltages at the housing. Grounding is therefore recommended.
3.4.4 Setting COMPANO 100 into operation
• Follow the instructions in chapter Product Startup on page 19 that describe how to properly and
safely set COMPANO 100 into operation.
• The warning symbol on the COMPANO 100 front panel indicates that the device is activated,
and that its outputs may carry dangerous voltages.
Even if the test set does not indicate dangerous output voltage, it's safe to always consider the
outputs live. The indicator could be defective. Also a software error or remote command could
accidentally start the test set. You may assume the outputs to be free of dangerous voltage when
the
emergency stop button is pressed (→ Wiring and Safe Connection on page 9).
