explosion-proof call station, 4 toggle
The explosion-proof stations have 4 integrated fastening holes for direct wall mounting. Apart
from the fastening screws, no further mounting material are necessary. The connection cable
is inserted through the cable gland and the wires are connected to the clamp terminals. There
are three cable glands available, one for the cable coming from the exchange DVS-21, a sec-
ond for the cable to the external loudspeaker, and the remaining one for Use of additional sig-
nalling units, e.g. indicator.
The required terminal connections for the above-mentioned applications are shown on the
circuit board, allowing the connection of wires even without the necessity of any drawings. The
terminals are accessible after removing the casing cover and the protective cover. In case of
service at the call station in areas with explosion risk the call stations must be made zero po-
tential during this process.
