OSRAM POWERTRONIC PT-FIT I ECG for HID lamps, with cable clamp - Manual (Page 8)

THE SYSTEM HID LAMP AND ECG
1.2.5.2. Installation of devices in luminaires or moun t-
ing the types with cable clamp in suspended ceilings
POWERTRONIC
® ECGs are available in two different
ver sions – each tailor-made for the requirements of the
light ing application they are being used in. Thus there
is a basic distinction between:
• ECG for (indoor and outdoor) installing in luminaires
• ECG with cable clamp for mounting independently,
for example, in suspended ceilings (indoors)

HID ECGs for installation in luminaires are each given the
abbreviation "S" in OSRAM terminology. The circuit-board
versions are distinguished with a B (for "Board"). Devices
equipped with a cable clamp are distinguished with an "I"
(for "Independent"), and those with an integrated plug-in
system are marked "SNAP".
ECGs for indoor installation generally have a metal casing
(aluminum or sheet steel) to facilitate the best possible
thermal coupling with the luminaire they are fi tted into.
Devices with cable clamp for independent mounting must
have the following properties:
1.) Protection against electric shock conforming to
IEC/EN 60598-1. An effective option for fulfi lling this
requirement would be to use casings made of non-
conducting materials, such as plastic (e.g. polyamide)
2.) Relief of push and pull strains on connection cable
It is possible to fasten all POWERTRONIC ® PTis to wood,
as it complies with the temperature requirements required
for certifi cation in accordance with VDE 0710-14 and
DIN VDE 0100-559. The devices carry the MM mark.
