Installation
The unit is only allowed to be installed and operated within the permissible temperature range. Please
ensure an adequate ventilation and avoid all direct contact between the unit and hot or aggressive
gases and liquids.
Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it
must be ensured that no danger can arise by touching the disconnected voltage-sources.
Units which are supplied by AC-voltages, must be connected exclusively by switches, respectively
circuit-breakers with the low voltage network. The switch or circuit-breaker must be placed as near as
possible to the unit and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated from
dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conformed to the provided voltage- and temperature-ranges.
Further all country- and application-specific standards, which are relevant for structure, form and
quality of the wires, must be ensured. Indications about the permissible wire cross-sections for wiring
are described in the Technical Specifications (see chapter
16)
.
Before first start-up it must be ensured that all connections and wires are firmly seated and secured in
the screw terminals. All (inclusively unused) terminals must be fastened by turning the relevant
screws clockwise up to the stop.
Overvoltages at the connections must be limited to values in accordance to the overvoltage category
II.
