necessary, the upper support screw can be fully tightened after hanging the device. In theory this is
only necessary in mobile applications. To access the upper support screw to fully tighten it, remove
the upper plastic grate.
Lower support screws: remove the lower plastic grate which gives access to the cabling
compartment. Carefully fix the device to the support with two screws (6-8 mm in diameter) using the
two mounting holes located at the bottom left and right of the cabling compartment.
3.4.2 VarioString VS-70
The VS-70 enclosure is fitted with a support plate to be mounted on
the back of the case using 4 screws M6, 8 mm long, and washers (see
fig. hereafter), before wall mounting. Mount it vertically with the
cable-glands downward.
The external cooling fan can be installed before or after the
equipment has been mounted on the wall.
The 4 mounting screws of the enclosure must be completely
tightened with a torque of (>3Nm - 10Nm<) in order to guarantee the
IP 54 protection index. Any unused cable glands should be closed in
a way that guarantees at least the same level of protection.
3.4.3 Assembling the cooling fan ECF-01
The VarioString VS-70 is supplied with an external cooling fan module (ECF-01). This module can be
installed before or after mounting the VarioString VS-70, on the wall.
This fan has a degree of protection IP54 and can be exposed to water spray without damage.
However, do not expose it to dirty water splashes in order to prevent mud or similar particles from
blocking the mechanism.
Assembly instructions:
1. Remove the plastic cap
and insert the connector
until the click sound.
2. Position the cover by
inserting the screws.
3. Fully tighten the two
screws.
