6.1 Preparation for use
6.1.1
Preparation for connection::
-
unpack the device and check the product for damage after transportation; in case of their detection,

".
ALL CONNECTIONS MUST BE PERFORMED WITH THE DEVICE BEING DEENERGIZED
.
An error in installation work may result in damage of the device and instruments connected to it.
To ensure reliability of electrical connections, flexible (multi-wire) conductors should be used with insulation
for voltage of at least 450 V, the ends of which must be stripped of insulation by 5 ± 0.5 mm and crimped with
bushings. It is recommended to use a wire with a cross-section of at least 1 mm
2
. The fastening of the wires
should exclude mechanical damage, twisting and abrasion of wire insulation.
DO NOT LEAVE BARE SPOTS OF WIRE EXTENDING OUTSIDE THE TERMINAL.
For reliable contact, it is necessary to tighten the terminal block screws with the force specified in
Table 1.
