The electrical rating is dependent on the microswitch fitted to the switch. The electrical rating is defined by each approval that the
microswitch complies with and is shown on the product nameplate, ie UL/CSA or IEC. It should be noted that the switch must be
used within the electrical rating specified from the approval you require. Table A lists the actual IEC ratings against the Designation
and Utilisation Category marked on the nameplate. If in doubt, seek guidance from factory.
Low Voltage Directive (LVD) – 2006/95/AC. Products with enclosure codes ‘W’ and ‘A’ supplied CE-
marked must be installed and used in accordance with the main instructions and this addendum supplied
with each product. Products rated lower than 50V ac and 75 V dc are outside the scope of the LVD. The
LVD does not apply to products with enclosure codes ‘H’ and ‘R’, for use in hazardous areas. Such
products are covered by the Explosive Atmospheres Directive ATEX – 94/9/EC and when CE-marked will
indicate compliance with this directive alone. The following directives do not apply to switch products
manufactured by Delta Controls:
Electromagnetic Compatibility EMC – 2004/08/EC.
Machinery Safety Directive MSD – 2006/42/EC.
WIRING
Junction box cable glands and adaptors. Optional Junction box code ‘C’ is supplied with an M20 x 1.5
tapped hole blanked with a red plug. Discard the red plug and fit a suitable proprietary brass or nylon M20
cable gland with thread length of 10 mm. Fit a fibre washer to the outside. See diagram 1.
Alternately the junction box may be supplied from the factory with a threaded adaptor ready to accept the
customer’s gland or conduit system.
Alternatives:
1) a metal or nylon adaptor may be used to accommodate other sizes of gland eg NPT, or conduit system.
See diagram 2.
Earthing / grounding – Use earthing point provided inside the junction box (when fitted). The user must
make suitable local earthing arrangement, if required, to ensure that metal glands / adaptors are earthed.
Pollution degree – all products are suitable for use in pollution degree 3.Ref EN60947-5-1
Electrical Isolation – these products are not suitable for electrical isolation. Always isolate circuit
separately to carry out any electrical work.
