Unpacking
Unpack all the parts of the delivered system. Avoid sharp-edged tools
that may damage the contents of the packaging.
Compare your order with our delivery note to check that you have received
all products in full. The article numbers printed on the nameplates simpli-
fies the identification of the devices.
Check all parts supplied for any evidence of damage in transit. Equip-
ment damaged in transit must not be used. If a device has sustained
damage, please contact BENDER. Details of who to contact are indi-
cated on the delivery documents.
When storing the devices in a cold environment as it is in winter the fol-
lowing is to be considered: Leave the devices to stand for 3 to 4 hours
at room temperature before connecting the power supply. When the
devices are moved from a cold to a warm environment, condensation
will be evident on all parts. Putting damp devices into operation risks
damaging electrical components and there is a danger of electric shock
on contact.

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 the
use of 6 A fuses.
Please note: The maximum voltage of the monitored system must not
exceed the rated insulation voltage of the measuring current trans-
former used in the EDS system and the IRDH575 or PGH...
Select the cables and cable lengths in accordance with the technical data
on page 62. If you use cables that are longer than those specified here,
BENDER cannot guarantee that the equipment will function safely.
