5.3. Electrical
Electrical equipment inspections, routine inspection
Without prejudice to the considerations of the insurer/Operator, it is recommended that the
electrical equipment of the MX130. MX230 be inspected and documented together with the
heating/cooling unit no less than every 12 months (see also DIN EN 60204-1 2007).
Emergency- STOP / Emergency-OFF
To conform with directive 2006/42/EG an EMERGENCY-STOP facility is to be made available
during installation within 2 metres of the equipment. Preferably, use a grounded wall socket for
the power supply to the unit. The socket must stay accessible. If the unit is directly connected to
the power supply, make sure the power supply line is provided with:
• a high-sensitivity differential switch (30mA) (residual current device RCD)
• a mains isolator switch with a contact gap of at least 3 mm.
• Supply protected by 3A - 6A MCB.
When additional security measures with EMERGENCY-OFF devices are required according to the
design and operation of the heat generator, these are to be installed on-site.
Obvious misuse
• Operation at incorrect voltage and/or frequency.
• Use in inappropriate system designs.
• Use of unpermitted installation materials.
Other hazards
• Overload of construction parts by the presence of unpredictable extreme values.
• Operational continuity at risk in the case of changed, non-permissible ambient conditions.
• Operational continuity at risk in the case of safety-control parts being taken out of service or
malfunctioning.
5.4. Staff qualification
The unit must be handled by a qualified person. The definition can be found in Appendix 2: Staff
qualification
