6.6.2 Directives and Standards
The product is designed according to the following directives.
− 2014/35/EU Low Voltage Directive (LVD)
− 2014/30/UE Electromagnetic Compatibility (EMC)
− DIRECTIVE 2011/65/EU RoHS II
Since this product is sold only as a sub-assembly of a chiller, it is out of the scope of Machinery Directive (2006/42/EC).
The product has been tested according to the following standards.
• EN 60204-1:2018 Safety of machinery - Electrical equipment of machines - Part 1: General requirements.
• EN 61439-1:2011 Low-voltage switchgear and controlgear assemblies - Part 1: General rules.
• EN 61439-2:2011 Low-voltage switchgear and controlgear assemblies - Part 2: Power switchgear and controlgear
assemblies.
• EN61000-6-2:2019 Generic EMC Immunity. Industrial environments.
• EN61000-6-4:2019 Generic EMC Emission. Industrial environments.
6.6.3 Panel Terminals
The input cable size is determined by the size of the machine (Chiller). Please refer to the databook informations.
The output terminals are factory connected to the compressor.
Permitted material for conductors: Copper.
6.6.4 Piping Connections
Cooling of the LHS VFDs is achieved using the refrigerant expanded liquid processed by the Chiller.
Refrigerant taken from the liquid line and released to the suction line of the machine, flows through input (IN) and output
(OUT) copper pipes connected to the back of the LHS Panel. (See fig.1)
Verify that pressure difference between access fitting 19 line L16 and access fitting 19 line L7 is lower than 2 bar, otherwise
provide to filter replacement.
If inverter panel disconnection is needed it is necessary to avoid that pressure is in these tubes before their removal.
To safely disconnect this line, follow the following steps.
• Close valves 23 line L16 (low armonic filter cooling line)
• Close valves 23 of the L16 line (low harmonic filter cooling line). Be sure that there is zero pressure in the lines
before proceeding with panel removal.
• Now it is possible to remove the piping from the inverter panel.
Failure to remove all refrigerant pressure from the whole refrigerant line can result in the pressure
ejection of components during disassembly operation and cause personal injury.
Any work on refrigerant lines has to be carried out only by trained technicians, please refer to DAIKIN
representative.
6.7 Maintenance
The maintenance of the product includes the interventions (inspection, verification, control, adjustment and replacement)
that are necessary following normal use.
For a good maintenance:
• Use only original spare parts, tools suitable for the purpose and in good condition.
• Comply with the intervention frequencies indicated in the manual for scheduled maintenance (preventive and
periodic). The distance (indicated in time or in work cycles) between one intervention and the other is to be
understood as maximum acceptable; therefore, it must not be exceeded; it can be abbreviated instead.
• Good preventive maintenance requires constant attention and continuous monitoring. To verify promptly the
cause of any anomalies such as excessive noise, overheating, etc. .... and remedy them.
• A timely removal of any causes of anomaly or malfunction avoids further damage to the equipment and ensures
operator safety.
The staff in charge of maintenance must be well trained and must have a thorough background knowledge of accident
prevention regulations; unauthorized personnel must remain outside the work area during operations. Even cleaning
activities are carried out only and exclusively during maintenance and with the product de-energized.
The product maintenance operations are divided, from the operational point of view, into two main categories:
