Intrinsically Safe Installation Ex "i"
The sections "Screwed fittings" and "Terminals" in
also apply to the intrinsically safe installation.
•
The housing cover (metal lid) covers the entire terminal com-
partment (see
, top).
•
Take the weight (approx. 1.5 kg) of the housing cover into con-
sideration when open and closing it so that it doesn't smash
down.
•
Install all four Allen screws (cylinder screws
ISO 4762 M5 x 20 - A4 - 70) for the housing cover with a tor-
gue of 4 Nm. Use Nord-Lock-washers (NL SS).
•
Seals of the screwed fittings must be designed in such a way
that the separation between intrinsically safe and non-intrinsi-
cally safe terminal room is not voided.
•
The semicircular plastic cover (Ex-e cover) covers the
non-intrinsically safe terminals (see
, bottom).
•
The Ex-e cover must prevent access to non-intrinsically safe
circuits with IP30 protection.
•
After installation, the Ex-e cover must completely cover the ter-
minal compartment for the power supply and RS485 interface
again.
•
Both screws (flat head screw ISO 7045 - M3 x 8 - 4.8) for fixing
the Ex-e cover must be mounted.
•
The housing cover is mounted correctly only if the pin on the
Ex-e cover smoothly clicks into the blind hole of the housing
cover.
•
With intrinsically safe versions
–
the metal cover to the terminal compartment may be
opened only for a short time for testing and adjustment.
–
the semicircular cover in the terminal compartment may be
opened only if the terminal compartment is no longer ener-
gized and no explosive atmosphere is present.
•
Devices with intrinsically safe circuits must not be connected to
intrinsically safe circuits any more if they have not been used
intrinsically safe before.
