Warning
：
●
Ensure the right setting of brake unit and brake resistor.
●
Do not make v
oltage resistance test
on the brake unit, or it will lead
semiconductor spares damaged in the main circuit of the brake unit.
●
Fix the srew when connecting, or the loose connection will lead fire
or creepage.
●
Do not touch the brake unit, the internal spares and printing board
after the brake unit is connected, otherwise it will lead to electric
shock. There is high voltage direct current inside.
●
Do not touch the heat sink of the brake unit and the brake resistors,
otherwise it will lead to scald or electric shock. There is high
temperature and heated spares inside after the brake unit is connected.
●
The brake resistor should be with temperature and other protection.
Because the brake unit is defective when the brake resistor keeps
heated, it should have been isolated itself. Powtran will not take the
responsibility of such accident caused by no automatic isolation.
●
The unit and brake resistor should be installed on the medium
with
flame retardancy
.
●
Connection is allowed only when the power is switched off
and completely out of power.
●
Only well-trained personnel are allowed to use this unit.
