DECOMMISSIONING AND DISPOSAL
De-commissioning
The supply input (auxiliary) for the equipment may include capacitors across the
supply or to earth. To avoid electric shock or energy hazards, after completely
isolating the supplies to the equipment (both poles of any dc supply), the
capacitors should be safely discharged via the external terminals prior to
de-commissioning.
Disposal
It is recommended that incineration and disposal to water courses is avoided.
The equipment should be disposed of in a safe manner. Any equipment
containing batteries should have them removed before disposal, taking
precautions to avoid short circuits. Particular regulations within the country of
operation, may apply to the disposal of the equipment.
6.
EQUIPMENT WHICH INCLUDES ELECTROMECHANICAL ELEMENTS
Electrical adjustments
It is possible to change current or voltage settings on some equipment by direct
physical adjustment e.g. adjustment of a plug-bridge setting. The electrical power
should be removed before making any change, to avoid the risk of electric shock.
Exposure of live parts
Removal of the cover may expose hazardous live parts such as relay contacts,
these should not be touched before removing the electrical power.
7. TECHNICAL
SPECIFICATIONS FOR SAFETY
Unless otherwise stated in the equipment technical manual, the following data is applicable.
7.1
Protective fuse rating
The recommended maximum rating of the external protective fuse for equipments is 16A,
high rupture capacity (HRC) Red Spot type NIT, or TIA, or equivalent. Unless otherwise
stated in equipment technical manual, the following data is applicable. The protective fuse
should be located as close to the unit as possible.
DANGER - CTS MUST NOT BE FUSED SINCE OPEN CIRCUITING THEM
MAY PRODUCE LETHAL HAZARDOUS VOLTAGES.
7.2 Protective
Class
IEC 60255-27: 2005
EN 60255-27: 2005
Class I (unless otherwise specified in the equipment
documentation). This equipment requires a protective
conductor (earth) connection to ensure user safety.
