Manual motor starter for potentially explosive areas
MS165
General description
The extended risks when using these devices in potentially explosive areas requires the consistent adherence to
the following notes and standards:
IEC/EN 60079-0 Explosive atmospheres – Part 0: General requirements
•
IEC/EN 60079-1 Explosive atmospheres – Part 1: Equipment protection by fl ameproof enclosure "d"
•
IEC/EN 60079-7 Explosive atmospheres – Part 7: Equipment protection by increased safety "e"
•
IEC/EN 60079-14 Explosive atmospheres - Part 14: Electrical installations design, selection and erection
•
IEC/EN 60079-17 Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
•
IEC/EN 60079-31 Explosive atmospheres – Part 31: Equipment dust ignition protection by enclosure
•
IEC/EN 50495 Safety devices required for the safe functioning of equipment with respect to explosion risks
•
The MS165 Manual motor starter is authorized under device group II, category (2) in the "G" area (areas with potentially
explosive gas, steam, smoke or air mixtures) and additionally for the "D" area (areas with combustible dust).

The MS165 Manual motor starter is not suitable for installation and/or operation in potentially explosive areas.
When using the devices in potentially explosive areas, preventive measures must be taken, e. g. within suitable enclosure.
Notes
For explosion-proof applications, the efficiency of the installed protection devices has to be verified prior to
•
commissioning!
The protection function of the device is the thermal overload protection and protection against short-circuits
•
in the motor. In case of an overload trip, the motor is switched off by opening the main contacts of the Manual
motor starter.
The safe state is the "tripped state", i.e., turning handle in 0-position or trip position.

Safety instructions
Attention! Hazardous voltage! Installation
•
by person with electrotechnical expertise
only.
Mounting and installation may only be done
•
by trained technical personnel, according to
the recognized technical rules, regulations,
and relevant standards!
Insufficiently tightened locking screws lead
•
to an inadmissible rise in temperature!
Always observe the permitted ambient
•
conditions (see technical data and catalog).
Devices with visible transport damage must
•
not be used.
