MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the PDM-8-MB power over Modbus module, read carefully
“Safety and Precautions”.
ATTENTION Do not disassemble the unit!
is unit is free-standing, but can also be surface mounted. If PDM-8-MB is to be
mounted onto a surface, choose a smooth mounting location e.g. a wall, a panel, etc.
(for dimensions between holes, see Fig. 1 Wall mounting) and follow these steps:

VERIFICATION OF THE INSTALLATION INSTRUCTIONS
After the module has been powered, the green LED on the enclosure should be on
meaning the power is appropriate (see Fig. 5 Operation LED indication).
Blinking green LEDs on the RJ connectors (RX and TX) show established
communication over Modbus RTU network (see Fig. 6 Communication LED
indications).
Fig. 5 Operation LED indication Fig. 6 Communication LED indications
ATTENTION After unplugging an RJ45 connector, wait minimum 60 seconds before reconnecting
another device to PDM-8-MB, otherwise you risk damaging your equipment.
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing at temperatures
-20— 40˚C .
WARRANTY AND RESTRICTIONS
Two years from the delivery date against defects in manufacturing. Any modifications
or alterations to the product after the date of publication relieve the manufacturer
of any responsibilities. e manufacturer bears no responsibility for any misprints or
mistakes in this data.
MAINTENANCE
In normal conditions these controllers are maintenance-free. If soiled, clean with a
dry or damp cloth. In case of heavy pollution, clean with a non-aggressive product.
In these circumstances, the unit should be disconnected from the main supply. Pay
attention that no fluids enter the unit. Only reconnect the controller to the main
supply when it is completely dry.
