3.1 Personnel
The use of the equipment is to be controlled and accepted by the operator. The personnel using
the unit have to be authorized by the operator or his representative. In case of further training of
using the equipment please contact the local supplier of the equipment.
3.2 Storage
SLAM Star units should be stored in a dry place within normal operating temperatures ie.
-20 °C
…
+40 °C. The units should not be stored in direct sunlight.
3.3 Before first use
Read this manual carefully before taking the product in to use. Archive the documents included
with the unit for further reference (manual, test report and declaration of conformity).
3.4 Visual inspection
As for all equipment to be used inside explosion hazardous area it is recommended that before
taking the unit into Ex –area, a visual re-inspection on the unit was taken and an analysis made
that the unit is not damaged (e.g. any part or wires are loose damaged or disconnected).
In case faults or defects on the unit are noticed, it is prohibited to take the unit into Ex –area until
corrective actions have been made.
3.5 Special attention on 2-pole use (24 V or 42 V)
Certain SLAM Star units are designed to be used together with step-down transformers. Using
SLAM Star unit with transformers of 2-pole socket outlets (without grounding / bonding) imposes
certain extra requirements for the unit itself.
Please inform us about your requirement for 2-pole use when placing the order. Products originally
manufactured for 3-pole use can not be modified later for 2-pole use by the operator. Such
modifications are only allowed to be carried out by the manufacturer or under supervision of the
manufacturer.
Note! Lack of equipotential bonding may cause danger in Ex –area, therefore please pay special
attention to all installations involving metallic parts. Static charging is especially noted on standards
referring to installations in explosion hazardous areas (e.g. EN/IEC 60079-14).
3.6 Connection to the supply
It is recommended that the unit is first connected to the mains / transformer before entering the
explosion hazardous area. Potential equalization should be arranged by the operator prior entering
explosion hazardous area.
SLAM Star units with 2-pole supply (without bonding connection) can be taken to explosion
hazardous area without connecting it to the supply first.
3.6.1 Requirements for supply (electricity)
Supply voltage
: Variation may be maximum ±10% from the value stated in the unit type label.
Current
: Maximum current of the system is 16 A.
