Electrical Protection; Electrical Requirements - PerkinElmer PTP-1 User Manual

Warnings and Safety Information . 15
If the fuses need replacing, use only those with the required current rating and the specified
type. Do not use makeshift fuses and do not short-circuit fuse holders.
When the instrument is connected to the electricity supply, the terminals may be live.
Removing covers other than those which can be removed by hand is likely to expose live
parts.
Capacitors inside the instrument may still be charged even if the instrument has been
disconnected from all voltage sources.
Disconnect the instrument from all voltage sources before it is opened for any adjustment,
replacement, maintenance or repair. Any adjustment, replacement, maintenance or repair
must be carried out by a PerkinElmer Service Engineer or other responsible body who is
aware of the hazard involved.

Electrical Protection

Installation Category - the instruments are able to withstand transient overvoltages typically
present on the MAINS supply. The normal level of transient overvoltages is impulse withstand
(overvoltage) category II of IEC 60364-4-443.
Pollution Degree 2 – usually only non-conductive atmospheric pollution of the equipment
occurs; occasionally, however, a temporary conductivity caused by condensation must be
expected.
Insulation Class 1 – earthed appliances.
Only connect to other equipment that meets the requirements of IEC 61010-1, IEC 60950 or
equivalent standards.

Electrical Requirements

Supply Voltage 100 - 120 V, 220 - 240 V, AC 50/60 Hz
NOTE: See Figure 11 and Figure 12 on page 53 for instructions how to set the correct
voltage on the fuse block located on the back panel above the power switch.
Power consumption 100 VA
