Electric Shock Hazards; Moving Machinery Hazards - Trox Technik X-CUBE X2 compact 2 Operating Instructions Manual

Leaks
CAUTION!
Risk of injury from slipping on a contaminated
floor!
If a machine or component leaks, liquids may be
getting onto the floor. People could slip and injure
themselves.
– Remove any liquids on the floor quickly.
– Wear non-slip safety shoes.
– Note the safety data sheets provided by the
liquid manufacturers.
– Attach warning notices and mandatory action
signs wherever liquids may get onto the floor.

1.7.2 Electric shock hazards

Electric current
DANGER!
Danger of death due to electric current!
Danger of electric shock! Do not touch any live com-
ponents! Damaged insulation or damaged parts are
a life threatening hazard.
– Have work on the electrical system carried out
only by skilled qualified electricians.
– Have work on the electrical system carried out
only by skilled qualified electricians.
– If the insulation is damaged, disconnect the
power supply immediately and have the insula-
tion repaired.
– Before you start working on electric systems and
equipment, switch off the supply voltage and
secure it against being switched on accidentally.
Comply with the following safety rules:
– Use the mains isolator to switch off the unit.
– Secure it against being switched on acciden-
tally.
– Disconnect the AHU from the mains power
supply for the building.
– Ensure that no voltage is present.
– Connect to the earth; short circuit connection.
– Either cover nearby parts that carry a voltage
or install barriers.
– Do not bypass or disable any fuses. Be sure
to maintain the correct current rating when you
replace fuses.
– Ensure that live parts do not come into contact
with moisture. Moisture can cause a short circuit.
Dangers when handling the AHU > Moving machinery hazards
Stored charges
DANGER!
Risk to life from charges stored in capacitors!
Many components contain capacitors, which may
hold electrical charges even after power is turned off.
Contact with these components can result in serious
or fatal injuries.
– Before you start working on any component that
contains capacitors, disconnect the component
from the power supply. Then wait for 10 minutes
to ensure that the capacitors have become fully
discharged.

1.7.3 Moving machinery hazards

Rotating parts of a fan
WARNING!
Risk of injury from rotating parts!
Rotating parts in the fan can cause severe injuries.
– Do not reach into the moving fan or tamper with
it.
– Do not open any covers or inspection access
panels while the unit is in operation.
– Make sure that the rotor is inaccessible while in
operation.
– The fan does not stop immediately! Check that
no parts are moving before you open an inspec-
tion access door.
– Switch off the system before you start working on
movable fan parts and secure it against acciden-
tally being switched on again. Wait until all parts
have come to a standstill.
Switch off the AHU before you start working
on movable fan parts and secure it against acci-
dentally being switched on again,
1.4 'Securing the unit against being switched
on accidentally' on page 8 . Wait until all parts
have come to a standstill.
Movable parts of multileaf dampers
WARNING!
Crushing hazard from movable parts!
Closing multileaf dampers may crush your hands
and arms.
– Do not reach between the damper blades.
– Prevent access to crush points: Either install
dampers on ducts or use fixed guards.
– Before you open an inspection access door,
switch off the air handling unit and secure it
against being switched on accidentally.
