Caution Statements
ASTAT XL Service Manual
1.2
Power-up procedure
Always apply control voltage before (or with) mains voltage.
QLxxB0023D to QLxxB0105D: After transportation, mechanical shock or rough handling there is a
possibility that the bypass contactor may have latched into the on state. To prevent the possibility of
the motor starting immediately, on first commissioning or operation after transportation, always
ensure that the control supply is applied before the power, so that the contactor state is initialised.
1.3
Stored charge
The starter contains capacitors that remain charged to a potentially dangerous voltage after the AC
supply has been disconnected. If the starter has been energised, the AC supply must be isolated at
least two minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual fault conditions,
the capacitors may fail to discharge. Do not assume that the capacitors have discharged. To
protect the user and the equipment, take due care when carrying out any work on the starter.
1.4
Short circuit
The ASTAT XL is not short circuit proof. After severe overload or short circuit, the operation of the ASTAT
XL should be fully tested by an authorised service agent.
1.5
Disposal Instructions
Equipment containing electrical components may not be disposed of together
with domestic waste.
It must be collected separately as electrical and electronic waste according to
local and currently valid legislation.
