1.1 IMPORTANT SAFETY INSTRUCTIONS AND SYMBOLS

SAVE THESE INSTRUCTIONS. This manual contains important instructions for model
PST-60S-48E that shall be followed during installation, operation and maintenance.

The following safety symbols will be used in this manual to highlight safety
and information:

WARNING!

Indicates possibility of physical harm to the user in case of non-compliance.

CAUTION!

Indicates possibility of damage to the equipment in case of non-compliance.

INFO

Indicates useful supplemental information.

Please read these instructions before installing or operating the unit to prevent personal
injury or damage to the unit.

1.2 SAFETY INSTRUCTIONS - GENERAL

Installation and wiring compliance

• Installation and wiring must comply with the Local and National Electrical Codes and

must be done by a certified electrician.

Preventing electrical shock

• Always connect the grounding connection on the unit to the appropriate grounding

system.

• Disassembly / repair should be carried out by qualified personnel only.

• Disconnect all AC and DC side connections before working on any circuits associated

with the unit. Turning the ON/OFF switch on the unit to OFF position may not entirely
remove dangerous voltages.

• Be careful when touching bare terminals of capacitors. Capacitors may retain high le-

thal voltages even after the power has been removed. Discharge the capacitors before
working on the circuits.

• There is NO Neutral in the "Schuko" AC output receptacle. Both the AC output sock-

ets are LIVE/HOT and are at elevated voltage with respect to the metal chassis Ground
of the inverter. Please read Section 8.5.1 for details.
