2.3 Improper use
Improper use will cause all claims for liability and warranties to be forfeited. Improper use
is defined as usage for purposes deviating from those mentioned above, especially:
●connection to mains supplies, which do not confirm to the regulations IEC 61010 or
IEC 60950
●connection to units which have exposed voltage-carrying parts
●connection to pumps or units which are not suitable for this purpose according to their
operating instructions
●operation of the devices in areas with ionizing radiation
3 Transport and storage
Units without external protection must not come into contact with electrostatically charge-
able materials and must not be moved within electrical or magnetic fields.
In rooms with moist or aggressive atmospheres, the unit must be airproof shrink-
wrapped in a plastic bag together with a bag of desiccant.
NOTICE
EC conformity
The manufacturer's declaration of conformity becomes invalid if the operator modifies
the original product or installs additional components.
Following installation into a plant and before commissioning, the operator must check
the entire system for compliance with the valid EU directives and reassess it accord-
ingly.

5.1 Assembly
Rack installation The unit is fitted in a casing that is suitable for installation in 19"/3HE rack modules.
Insert the unit in the guiderails of a 19"/3HE rack and screw on the front panel secure-
ly with four fixing screws provided as part of the scope of supply.
5.2 Connecting to the mains power supply
The DPG 202 is equipped with an universal power supply with an input voltage range of
95 ... 265 V AC.
NOTICE
