ELT-400 2 Safety instructions
2-3
2.3 AC adapter / charger unit
2.4 Faults and excessive stresses
Take the unit out of service and secure it against unintentional operation if
safe operation is no longer possible. This will be the case, for example, if:
• the instrument shows visible signs of damage
• the instrument does not work
• the instrument has been subjected to any kind of stress that exceeds the
permitted limits.
Contact your local Service Center in such cases.
Danger
Electric shock
Parts carrying dangerous voltages that may cause injury may be exposed if
the AC adapter / charger unit is damaged.
⇒ Do not use an AC adapter / charger unit that has been damaged.
Caution
Destruction
The wrong AC line voltage, condensation, excessively high or low
temperatures and poor ventilation can lead to destruction of the
AC adapter / charger unit.
⇒ Before connecting up the AC adapter / charger unit make sure that
the operating voltage of the AC adapter / charger unit is the same as the
AC line voltage.
⇒ Do not use the AC adapter / charger unit if condensation has formed on
it. If condensation is unavoidable, e.g. because the instrument has been
moved from a cold to a warm room, wait until the unit has dried off before
connecting it up.
⇒ Only use the AC adapter / charger unit indoors and at temperatures
between +5 °C and +45 °C.
