2 Installation

DOL 53 should be installed at the centre of the area to be monitored. This ensures optimum measurements.

DOL 53 must be installed out of reach of animals, accessible for maintenance work. It must be suspended from

the lug at the end of the housing or alternatively with a mounting bracket on the wall.

DOL 53 must not be mounted near the fresh air supply, in front of windows or doors, large electri-

cal consumers (electromagnetic influences), in exhaust air ducts, behind air washers or behind

screens. DOL 53 must not be mounted in inaccessible areas. Protect against direct exposure to

dust or splash water. For wall mounting, unobstructed gas entry must be ensured.

DOL 53 must not be suspended from the electric cable.

Figure 2: DOL 53 must be mounted vertically with the sensor pointing down; ±30° at a location with low vibration and, as far

as possible, stable temperatures.

fied personnel in compliance with the applicable national and international standard EN 60204-1

and any other EU standards that are applicable in Europe.

The scope of delivery includes an approx. 2.5-

meter-long cable connection (5) for the electrical

installation up to the junction box (1). For the

electrical supply and signal transmission to the

control unit cables with adequate cross-section

must be used. Connect the cable from the instal-

lation kit to the connector (4) and in the junction

box (1). Connect the GND cable in the control

unit to protective earth.

The cable must be routed in a manner to obtain a

"water loop" (2) for water to drop off Insert the ca-
