ATTENTION
• Ensure that the device is not live (power supply and signals) before
wiring work is completed. .
CAUTION
The device must be connected to the equipotential bonding system at the
place of use and earthed. Use the equipotential bonding connection (PA)
on the underside of the housing.
Check the voltage used at the place of use to ensure it is correct and suitable as
described in the following instructions. Ensure that the same earthing potentials are
always connected to each other.
The device will not work if the connections are reversed (polarity reversal
protection). In some cases, the fuse also triggers and must be replased. This
protective equipment (thermal trips and electrical fuses) cannot be
accessed without opening the housing. Please contact your TAC if you are
not authorized to open the housing and replace the protective equipment.
ATTENTION
When making the contact and selecting the fastening materials, comply with the
appropriate regulations, for example IEC/EN 60079-14.
ATTENTION
When connecting the earthing cable, check that it has a good, permanent,
stable electrical contact. Use earthing points outside the device as
discriped bevore
ATTENTION
Tighten the screws on any unused terminals.
Check that the connectors are secure when all the work has been
completed.

In addition to the wiring work, special parameterization may be required
e.g. for Modbus communication. Detailed information is given in the
software manual.
