4 Ingress Protection Ratings
Ratings quoted are for each Telecell type and also the dimming module correctly installed in suitable
mounting hardware, itself having appropriate ingress protection.
4.1 NEMA Telecell
This variant is entirely located outside the luminaire. It attaches to the luminaire using its moulded-in
electrical contacts. The NEMA employs an o-ring seal and shrouding skirt to achieve an IP rating of 65.
4.2 Conduit Telecell
This variant has the same external features as the NEMA but attaches to the luminaire via a Ø20 mm
hole. Ingress protection via this hole is provided by a rubber bung. The ingress protection around the
external surfaces and mounting hole is IP65.
The surfaces of the Conduit Telecell accessible from the inside of the luminaire are rated to IP55. It is a
requirement that the Telecell is always installed in a luminaire or other hardware with ingress protection
rated for safe electrical operation in the indoor or outdoor environment for which it is intended. This
provides a safe environment for the internal surfaces and connection of the Telecell.
