If spilt on the equipment, they can:
– cause the stereomicroscopes and accessories to become
electrically live, endangering personnel,

Inspect cables regularly for damage. Defective cables can:
– directly endanger personnel,
– cause the stereomicroscopes and accessories to become
electrically live, endangering personnel.
Route cables with care. Make sure that personnel do not get
entangled with them. The instrument could fall over, fall down,
become damaged, damage other equipment, or cause personal
injury.
Only authorized Leica personnel are permitted to repair electri-
cal equipment. Before opening up the equipment, pull out the
power cable. If you touch the live interior of the equipment, you
may receive an electric shock.
Ensure that the voltage setting on the equipment is correct.
A wrong setting can cause damage to the equipment.
When connecting power-consuming devices to the transform-
ers, do not exceed the maximum permitted loading, as this can
cause damage to the equipment.
• Before changing a bulb, disconnect the power cable.
• Never attempt to touch the inside of a lamp housing or
transmitted-light stand while the instrument is connected
to the power supply.
• Before changing a bulb, wait until it is cool, otherwise you
may burn your fingers.
