4.2 Fuses, max. voltage, cable lengths
Equip the supply voltage of all system components with fuses so that
they are protected in the event of a short circuit. We recommend that
you use 6 A fuses. For UL and CSA applications, the use of 5 A fuses
is mandatory.
Please note: The maximum voltage of the monitored system must not
exceed the rated insulation voltage of the measuring current transfor-
mer used in the EDS system and the IRDH575 or PGH…
Select the cables and cable lengths in accordance with the technical
data on Seite 70. If you use cables that are longer than those specified
here, Bender cannot guarantee that the equipment will function safely.
4.3 Notes on mounting
The devices are suitable for the following types of installation:
standard distribution panels according to DIN 43871 or
DIN rail mounting according to IEC 60715 or
screw mounting using M4 screws.
Mount the measuring current transformers in accordance with the notes in
the "Transformer installation" technical information. When connecting the
measuring current transformers, it is essential that you observe the maximum
cable lengths.
Before mounting the device and working on the device
connections, make sure that the power supply voltage has
been disconnected. Failure to comply with this requirement
will expose personnel to the risk of electric shock.
Furthermore, the electrical installation may sustain
damage and the device may be destroyed beyond repair.
