5. COMMISSIONING
5.1. Safety instructions
DANGER!
High voltage! Danger!
Do not touch live components.
Ensure that the switchgear is only operated by qualified personnel who are familiar
with the operating instructions and observe the warnings.
ATTENTION!
Risk of injury! During operation of electrical equipment and switchgear, parts of this
equipment are under dangerous electrical voltage. Mechanical components may move
quickly, even remotely controlled.
Do not remove covers.
Do not reach into openings.
Do not touch circuit breaker poles and operating rods.
The perfect and safe operation of this switchgear is conditional on:
• Correct assembly and installation
• Diligent operation Installation and operation of this switchgear are conditional on observance
of the following standard of electrical installations in buildings: IEC 60364-5-53
5.2. Preliminary work
5.2.1. Instructing the operating personnel
The operating personnel should be given the operating instructions in good time.
Instruct operating personnel in theory and practice of switchgear operation.
Ensure that the operating personnel are familiar with all operational details when
commissioning takes place.
5.2.2. Drying dampness
If the switchgear becomes damp by condensation or high humidity, e.g. prevailing during
erection, the switchgear must be dried. Use several electrical heaters of 1000 to 2000 W each.
Alternatively switch on the anti-condensation heater if such is part of the switchgear.
The warm air has to flow through all compartments of the switchgear until it is completely
dried. Withdraw the truck out of the panel to support the air flow.
5.2.3. Checking the installation work and the accessories
Make sure that the following accessories are ready to hand:
• Operating instructions
• Hand crank for truck operation
• Operating lever for the feeder earthing switch
• Hand crank for the spring energy store
• Double-bit key for the racking mechanism
• Double-bit key for the door of the low-voltage compartment
• Circuit diagrams
• Warning signs
• Earthing and short-circuiting facility (optional)
• Voltage tester or detecting system (optional)
• Lower shutter opening tool (optional)
Ensure that the installation work has been performed properly.
