Insulation Resistance - Premium EDT-150 Manual Del Usuario

Method
Equipment disconnected from power, earthed, with the terminals of each group short-circuited together.
I/O groups formed:
AC power terminals.
-
DC power terminals.
-
Ethernet and Alarms.
-

Insulation resistance

> 100Mohm with ±500Vdc between each group and earth. Reading performed 5 seconds after applying voltage.
Note: The test is performed at the beginning and end of all isolation measures. Difference between the two
measures is <20%.
Dielectric strength
The voltage is applied for 1 minute without producing any disruptive discharge or a change in the insulation
resistance.
AC power terminal = 3kVac / 50Hz between active parts and GND (*) and 10 lightning pulses (±5kV 1.2/50μs)
-
DC power terminals = 2.5kVca / 50Hz between active parts and GND (*) and 10 lightning pulses (5kV
-
1.2/50μs) 5 in each polarity.
Test carried out by applying voltage to all points: GND, output s Vdc, other signals ... short circuited together
(in groups) with the AC power input earthed
(*) GND is considered to be a metallic sheet covering totally the outer part of the equipment connected to the
metallic parts of the enclosure.
