Warnings and instructions for mounting to the panel

Instructions for installation category II,
pollution level 2, double isolation.
The equipment is intended for permanent indoor
installations within their own enclosure or panel mounted
enclosing the rear housing and exposed terminals on the
back
• only for models with 11...27Vac/dc power supply:
supply from Class 2 or low voltage limited energy
source
• the power supply lines must be separate from the
controller input and output ones
• group the instruments together keeping them separate
from the powered part of the relay
• do not install high-power remote switches, contactors,
relays, thyristor power units (especially the "phase
angle" type), motors, etc. in the same switchboard
• avoid dust, humidity, corrosive gasses and heat
sources
• do not block the ventilation holes: the working
temperature must be between 0...50°C
• surrounding air: 50°C
• use 60/75°C copper (Cu) conductor only, wire size
range 2x N. 22 - 14AWG, Solid/Stranded
• use terminal tightening torque 0.5Nm

Nominal ambient conditions

Before supplying the Indicator with power,
make sure that the mains voltage is the same
as that shown in the last number of the order
code.
Example:
400 – x – x – x – 0 = 11...27Vac/dc
400 – x – x – x – 1 = 100...240Vac
