The recommendations of European standardEN 60204-1 (machine safety - electrical machine components - part 1: generalregulations - corresponds to IEC 60204-1) are specifically taken into account,when designing the electrical unit equipment.NOTES:• Generally the recommendations of IEC 60364 are accepted as compliancewith the requirements of the installation directives. Conformance with EN60204-1 is the best means of ensuring compliance with the Machines Directive§ 1.5.1.• Annex B of EN 60204-1 describes the electrical characteristics used for theoperation of the machines.1. The operating environment for the 30RW and 30RWA chillers is specifiedbelow:Environment* - Environment as classified in IEC 60364 § 3:- ambient temperature range: +5°C to +40°C, class AA4- humidity range (non-condensing)*:- 50% relative humidity at 40°C- 90% relative humidity at 20°C- altitude: ≤ 2000 m (see note for table 4.4 - Electrical data, hydronic module)- indoor installation*- presence of water: class AD2* (possibility of water droplets)- presence of hard solids, class AE2* (no significant dust present)- presence of corrosive and polluting substances, class AF1 (negligible)- vibration and shock, class AG2, AH2- competence of personnel, class BA4* (trained personnel - IEC 60364)2. Power supply frequency variation: ± 2 Hz.3. The neutral (N) conductor must not be connected directly to the unit (ifnecessary use a transformer).4. Over-current protection of the power supply conductors is not provided withthe unit.5. The factory-installed disconnect switch(es)/circuit breaker(s) is (are) of a typesuitable for power interruption in accordance with EN 60947.6. The units are designed for simplified connection on TN(s) networks (IEC 60364).For IT networks provide a local earth and consult competent local organisationsto complete the electrical installation.7. Derived currents: If protection by monitoring of derived currents is necessary toensure the safety of the installation, the control of the cut-out value must take thepresence of leak currents into consideration that result from the use of frequencyconverters in the unit. A value of at least 150 mA is recommended to controldifferential protection devices.NOTE: If particular aspects of an actual installation do not conform to theconditions described above, or if there are other conditions which shouldbe considered, always contact your local Carrier representative.* The protection level of the control boxes required to conform to this class isIP21B (according to reference document IEC 60529). All 30RW and 30RWAunits with correctly installed casing panels fulfil this protection condition.
