Warnings
draw attention to the facts, constituting safety risks to the operator.
Cautions
indicate conditions and facts that may cause damage to the uninterrup-
tible power supply MEg101.4.
• The operator engaged in installation of the power supply MEg101.4, commissio-
ning, maintenance and dismantling must be equipped with personal protective
equipment against electrical shock and must use other protection devices as well.
• The operator engaged in installation of the power supply MEg101.4, commissio-
ning, maintenance and disassembly must have qualifications for work near dange-
rous voltages. The operator must also be trained to administer first aid.
• The power supply MEg101.4 may be operated by skilled personnel only.
• The power supply MEg101.4 may be connected to supply by permanent maximum
voltages 300 V
AC
and 300 V
DC
, otherwise there is a risk of electrical injury.
• It is necessary to incorporate circuit breakers in the circuits of the power supply
MEg101.4 with respect to the type of supply voltage, see Fig. 4.
• Repairs of the power supply MEg101.4 may only be carried out by the manufactu-
rer or service organizations authorized by the manufacturer.
• The replacement of FU1 fuse for AC or DC supply voltage may be carried out only
with the supply voltage switched off.
• When connecting an external 12 V battery the terminals must not to be short circu-
ited and as the last the inlet connects to positive pole of the supply source.
