Installation and Operating Instructions
For additional safety instructions about DWM 1000 devices, refer to page 5
Use one safety device per fuse (In = 100mA) in the power supply circuit. Use a switchgear device
(switch, circuit-breaker) to disconnect the signal converter adjacent to the device. Switchgear must
fully isolate the device (disconnect the 2 power lines), agree with the IEC 60947-1 and IEC 60947-3
standards and be identified as switchgear for this device.
Make sure that the electrical cable diameter is between 8 and 12 mm. Make sure that the cable gland
holds the cable tightly. Electrical cables must have a temperature rating that agrees with the operating
conditions.
Use a damp cloth to clean the device. Do not use aggressive or corrosive cleaning agents.

Do not open the device when it is energized. There is a risk of injury or death from dangerous
voltages if you touch internal components after the device is connected to power supply. Do
not operate the device without its cover.

De-energize the device and disconnect the power supply before you do work on the electrical
connections. Refer to the voltage data on the nameplate!

The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.

Obey the national regulations for electrical installations!

Risk of injury (burns) to personnel who touch the device, depending on the environmental and
operating conditions.

Obey fully the local occupational health and safety regulations. Only approved personnel can
do work on electrical components of the measuring device.
