R40 MODEM EXPANDER MODULE p 17
Safety Precautions
The R40 module is a Class II equipment, i.e. the use of a protective earthing
is not required because of the insulation provided between the primary circuit
(mains/relay contacts) and the secondary circuit.
The R40 module is intended for Installation Category II (Overvoltage Category)
which defines the impulse withstand voltage. Installation Category II cor-
responds to normal local distribution level, or “Mains Plug” level.
Before any service of the unit is undertaken, the disconnect devices must
be operated to disconnect power to the unit.
All cables must be entered via cable glands that are adequately tightened to
prohibit the cords from being pushed into/pulled out of the unit. Glands must be
in compliance with the UL94 flame class 94V-0.
Cables connected to the mains supply must use dedicated cable glands in
order to prohibit mixing of signal and power cords.
Due to electric shock hazard, the cover must always be mounted during
normal operation.
