2. Safety instructions
This instrument is produced in accordance with Class II of IEC 348 and VDE 0411.
When delivered the instrument has been tested to meet all functions described. Befo-
re installing the instrument please read the mounting and servicing instructions.
We have no liability or responsibility to customer or any other person or entity with re-
spect to any liability, loss or damage caused or alleged to be caused directly or
indirectly by equipment or software sold or furnished by us. Read the installation in-
struction carefully. No liability will be assumed for any damage caused by improper
installation.
Inspect the instrument module carton for obvious damage. Be shure there are no
shipping and handing damages on the module before processing. Do not apply po-
wer to the instrument if it has been damaged.
ERMA’s warranty does not apply to defects resulting from action of the buyer, such as
mishandling, improper interfacing, operation outside of design limits, improper repair
or unauthorized modifications.

4.1. General instructions
•It is forbidden to plug or unplug connectors with voltage applied
•Attach input and output wires to the connectors only without voltages
applied
•Cords must be provided with sleeves
•Attention must be paid that the power supply voltage applied will
agree with voltage noticed at the name plate.
•The instrument has no power-on switch, so it will be in operation as
soon as the power is connected.
4.2. Hints against noisy environment
All inputs and outputs are protected against noisy environment and high voltage
spikes. Nevertheless the location should be selected to ensure that no capacitive or
inductive interference can have an effect on the instrument or the connection lines.
It is advisable:
•To use shielded cables.
•The wiring of shields and ground (0V) should be star-shaped.
•The distance to interference sources should be as long as possible. If
necessary, protective screen or metal enclosures must be provided.
•Coils of relays must be supplied with filters.
•Parallel wiring of input signals and AC power lines should be avoi-
ded.
