OTM-20 Installation and Operation Handbook
OPERATOR'S SAFETY SUMMARY
CAUTION — these instructions are for use by qualified personnel only. To reduce
the risk of electric shock, do not perform this installation or any servicing unless you
are qualified to do so. Refer all servicing to qualified service personnel.
To ensure 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.
