Installation
Installation for the equipment is by panel(panel drill 92
+0.8
x 92
+0.8
m.m., according to
DIN 43 700). All connections must remain inside the electrical board.
Bear in mind that when the equipment is connected, the terminals may be
dangerous if touched. Opening covers or removing parts may access parts
which are dangerous if touched. The equipment must not be used until it is
fully installed.
The equipment must be connected to a power supply circuit protected with gl (IEC
269) or type M fuses between 0.5 and 2 A. It must have an overload/short circuit
switch or equivalent device in order to disconnect the equipment from the power
supply. The power supply circuit and the voltage measurement circuit is connected
with a cable with a minimum cross section of 1 mm
2
.
The secondary line for the current transformer shall have a minimum cross section of
2.5 mm
