Ensuring Safety
•
The unit should not be exposed to dripping or splashing, and no objects filled with
liquids, such as vases, shall be placed on the unit.
•
When the unit is to be permanently cabled, connect the protective ground conductor
before making any other connections.
•
Operate built-in units only when they are properly fitted into the system.
•
For permanently cabled units without built-in fuses, automatic switches, or similar
protective facilities, the AC supply line must be fitted with fuses rated to the units.
•
Before switching on the unit, ensure that the operating voltage set at the unit
matches the line voltage, if appropriate. If a different operating voltage is to be set,
use a fuse with the appropriate rating. Refer to the Installation Instructions.
•
Units of Protection Class I with an AC supply cable and plug that can be
disconnected must be operated only from a power socket with protective ground
contact:
•
Do not use an extension cable—it can render the protective ground
connection ineffective.
•
Do not intentionally interrupt the protective ground conductor.
•
Do not break the protective ground conductor inside or outside the unit or
loosen the protective ground connection; such actions can cause the unit to
become electrically hazardous.
•
Before opening the unit, isolate it from the AC supply. Then ensure that:
•
Adjustments, part replacements, maintenance, and repairs are carried out by
qualified personnel only.
•
Safety regulations and rules are observed to prevent accidents.
•
Only original parts are used to replace parts relevant to safety (for example,
the power on/off switches, power transformers, and fuses).
•
Replaceable fuses can be hazardous when live. Before replacing a fuse, disconnect
the AC power source.
•
Use caution when cleaning the equipment; isopropyl alcohol or similar solvents can
damage or remove the labels.
•
Observe any additional safety instructions specified in this manual.
