3.1 Mounting and Electrical Connection
WARNING! Shock potential.
For applications with high work-
ing voltages, take measures to prevent accidental contact and en-
sure sufficient clearance or insulation between adjacent devices.
Do not connect the product power supply or apply measuring volt-
age until it has been professionally installed.
Installation Conditions
Install the product in a suitable housing (enclosure/distribution
box) that ensures pollution degree PD 2 or higher and protects
from mechanical impact. The housing may only be opened using a
tool (wrench).
The devices are snapped onto mounting rails in accordance with
EN 60715 with a width of 35 mm. They are secured on the side
using suitable end brackets.
Conductor cross-section: 0.2 mm

(AWG 24-12).
NOTICE!
Only use copper cables that are process temperature
resistant to at least 75 °C.
CAUTION! Install a two-pole disconnect device between the
product and the mains.
Isolation
Applications with a working voltage in one of the circuits in excess
of the specified reinforced insulation and the possible contact of a
person with a different circuit require an additional protective mea-
sure in accordance with the relevant codes and standards for the
installation of electrical equipment (e.g., VDE 0100 and NEC), such
as:
• Extra insulation
• Protective connection or shielding
• Automatic disconnection from the power supply
• Current or voltage limiting device
