2.4 Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
Transportation and Installation
CAUTION
Ensure that installation position and material can withstand the weight of the FC 3500
DC. Install according to the information in the Instruction Manual.
· Do not operate if the FC 3500 DC is damaged or has parts missing.
· Do not stand or rest heavy objects on the FC 3500 DC.
· Prevent screws, wire fragments or other conductive bodies or oil or other flammable
substance from entering the FC 3500 DC.
· Place during installation a covering plate over the FC 3500 DC to prevent metal powder,
from drilling activity, being fallen into the unit. Remove covering plate always after
finishing installation otherwise, it will give a negative effect on the ventilation of the unit.
And the unit can even be overheated by it.
· Do not drop the FC 3500 DC or subject it to impact.
· Use the FC 3500 DC under the environmental conditions given in the technical data.
Wirring
CAUTION
Use only cables and wiring capable of withstanding temperatures of ≥70
O
C.
· It is recommended to use insulation-sleeved solderless terminals for power supply, heater,
valve and fan wiring.
· Connect wires only when the unit is switched off.
· Any person who is involved in the wiring or inspection of this equipment should be fully
competent to do the work.
· Check if the nominal supply voltage from the FC 3500 DC is equal to the AC-supply
voltage. A incorrect power supply voltage can lead to fire, injury or failure.
· Place interrupters, capable of switching off frequency controllers, like automatic-MCCB-
fuses, between the power supply and the FC 3500 DC and take other safety actions to
prevent short-circuit in the external wiring. If no safety action is installed, this can lead to
fire, injury or failure.
· Take care for correct wiring which is firmly mounted otherwise measurement mismatch,
injury or damage to the unit can occur.
· Do not connect a AC supply to the outputs terminals of fan, heater or water valve. This can
lead to damage or failure of the unit.
