This quick-start guide applies to the EDS440/441-L-CN, W-L-CN,
-S-CN, W-S-CN, EDS441-LAB-4-CN and W-CN devices. It does not
replace the operating manual.
The operating manual can be found on our homepage under
www.bender.de/manuals.
Intended use
The insulation fault locator EDS44… locates insulation faults in
ungrounded DC, AC and three-phase supplies (IT systems).
With an active test current generator (PGH), AC and three-phase
networks in the range AC 0…1000 V and DC networks in the
range DC 0…1500 V can, depending on the PGH type, be monitored. An AC residual current in the range 42 Hz…1 kHz, 100
mA…20 A (EDS440) or 50/60 Hz, 100 mA…2 A (EDS441) can be
displayed.
Network configuration, mains voltage, mains frequency, leakage capacitance and test current influence the
responsiveness of the EDS system. Please refer to the response sensitivity curve in the manual.
Make sure the system is de-energized before installing
the device. Otherwise there is a risk of electric shock. Furthermore, the electrical installation may be damaged
and the device may be destroyed beyond repair.
DIN rail mounting
1. Fix one of the mounting clips supplied, either manually or by
means of a tool, into position as shown in the illustration below.
2. EDS…-S-CN only: Attach the BB bus to the device. To do this,
refer to the BB bus mounting instructions supplied.
3. Snap the EDS… device onto the DIN rail.
Screw mounting
1. Fix the two mounting clips supplied, either manually or by
means of a tool, into position as shown in the illustration
below.
2. Drill the mounting holes for the M4 thread according to the
dimensioned drilling template.
对于 UL 应用:
仅使用 60/75 °C 的铜线 ! 对于 UL 和 CSA 应用,
电源电压必须通过 5A 的保险丝进行保护。
被监视网络的最大电压不得大于所有使用中组件
的额定绝缘电压。根据技术参数选择电缆和电缆长
度。
Connection
Connect the device according to the wiring diagram. Also refer to
the technical data. After connecting the device, install the upper
and lower terminal cover.
Risk of electric shock!
Make sure the system is de-energized before installing
the device. Otherwise there is a risk of electric shock. Furthermore, the electrical installation may be damaged
and the device may be destroyed beyond repair.
Provide line protection!
According to DIN VDE 0100-430, a line protection shall
be provided for the supply voltage.
For UL applications:
Use 60/75 °C copper wires only! For UL and CSA applications, the supply voltage must be protected via 5 A fuses.
The maximum voltage of the monitored network must
not be greater than the rated insulation voltage of all
components used. Select cables and cable lengths according to the technical data.
