Mitsubishi Electric MELPRO S Series Operation Manual page 3

[Installation, wiring work]
The equipment must be correctly grounded using the designated grounding terminals where they exist.
Failure to do so may lead to the risk of electric shock, equipment failure, malfunction or failure to
operate.
Be sure to return all terminal covers, protection covers to their original positions once any work is
complete. If they remain uncovered there is a risk of electrical shock.
 Ensure that the equipment is mounted and connected correctly. Otherwise, there are risks of failure,
burning, or mal-operation.
 Securely tighten the terminal connection screws. Otherwise, there are risks of failure and burning.
 Ensure that the equipment is connected correctly in accordance with the details shown on the
connection terminals. Otherwise, there is the risk of failure, burning, malfunction, or maloperation.
 Ensure that the equipment is connected correctly in accordance with the phase sequence details shown
on the connection terminals. Otherwise, there is the risk of failure, burning, malfunction, or maloperation.
 All power supplies to the equipment must be of suitable capacity and rated load to avoid the risk of
malfunction and maloperation.
 The appropriate connectors must be used to ensure compatibility with the connector terminals to avoid
the risks of failure or fire.
[Operating and Setting the equipment]
The equipment must only be operated and handled by qualified personnel. Otherwise, there are risks of
electric shock, injury, failure, malfunction, and maloperation.
Handling and maintenance of the equipment must only be carried out after gaining a thorough
understanding of the instruction manual. Otherwise, there is the risk of electric shock, injury, failure,
malfunction, or maloperation.
The equipment must be used within the following range limits. Otherwise, there is a risk of reducing the
performance and life of the product.
• Variation range of control power supply voltage
• Frequency variation
• Ambient temperature
• Altitude
• The state where abnormal vibration, shock, inclination, magnetic field are not applied
• The state where it is not exposed to harmful smoke/gas, saline gas, water droplet or vapor,
excessive dust or fine powder, explosive gas or fine powder, wind & rain.
While energized, do not tamper with or remove any components other than those which have been
designated. Otherwise, there is a risk of failure, malfunction, or maloperation.
When changing the setting value during the energized state, ensure that all trip circuits are locked in
order not to operate. Otherwise, there is a risk of malfunction.
