4.4 Certificates and approvals
Explosion protection
The CYH112 holder may also be used in hazardous areas in Zone 1 and 2.
The holder does not fall within the scope of ATEX Directive 2014/34/EU as it does not
have a potential source of ignition of its own. Consequently, the holder does not bear
ATEX identification marking. Potential equalization must be implemented as described in
the "Installation conditions" section.

 3 Extension as a function of the suspended load
The maximum permitted load when mounting on a rail and using a pendulum holder with
a pendulum adapter is 5 kg (11 lb). Potential equalization must be implemented at the
place of installation. All electrically conductive parts must be interconnected.
Cable
The cable to the sensor is routed outside along the pipe. Hook-and-loop cable ties can be
ordered as accessories to secure the cable.
Cable routing for the power supply must be implemented by the customer onsite.

 The minimum distance between the bores and the basin rim is 40 mm (1.57 in).
2. Mark the securing holes for the base on the floor.
3. Drill the securing holes with a 12 mm drill.
4. Install the 4 chemical anchors.
5. Firmly screw down the base.
