5 Commissioning
Maschinenfabrik Reinhausen GmbH 2016 64 5163667/00 EN TRAFOGUARD® ISM®
Commissioning
You need to set several parameters and perform function tests before com-
missioning the device. These are described in the following sections.
NOTICE Damage to device and system periphery
An incorrectly connected device can lead to damage to the device and sys-
tem periphery.
► Check the entire configuration before commissioning.
Performing tests
Please contact Maschinenfabrik Reinhausen GmbH (MR) if any aspect of
the tests is not clear.
Ground test
For commissioning, carry out a ground test (check of the impedance of the
protective bonding) in accordance with IEC 61010-1. Note the following in-
formation:
▪
Test current: 2 times the measurement current of the overcurrent pro-
tection device of the supply line.
▪ Test duration: 1 minute for each measurement point.
▪ The measured voltage between the measurement point and the protec-
tive conductor must be smaller than 10 V.
Proceed as follows to carry out the ground test:
1.
Feed the test current at the fixing screw of assembly DIO 28-15 or DIO
42-20 using a constant current source and measure the voltage be-
tween the measurement point and the protective conductor.
ð
The measured voltage must remain less than 10 V over a duration
of 1 minute.
