Connecting Load Cables; Earth Leakage Relay And Grounding - Shindaiwa DG50MKM-P Owner's And Operator's Manual

< Note >
 Select cable with a thickness that ensures that the voltage drop across the cable will be
within 5% of the rated voltage.
Expedient Formula: the voltage drop of cables.
 3-Phase 3-Wire

7-2. Connecting Load Cables

WARNING : ELECTRIC SHOCK
 Before connecting or disconnecting the load cables to/from the output
terminal, always turn the output circuit breakers to the OFF position, stop
the engine, and turn the Power Switch to the OFF position.
 Close the output terminal cover before operating.
 Do not touch the generator if the Alternator or casing becomes wet during
operation.
CAUTION : FIRE
 Do not connect the generator output to indoor wiring.
< Note >
 Divide loads into 3 circuits proportionally as possible, when using the maximum output
power especially, and connect them to each phase (R,S,T) respectively.
 Be careful to limit the current under the rated current per the phase.
 Note that the 1-phase output power decreases when 3-phase output power is used
simultaneously.
 Be careful to limit the total current under the rated output current when using 1-Phase
and 3-Phase output simultaneously.

7-3. Earth Leakage Relay and Grounding

WARNING : ELECTRIC SHOCK
 Ground the every grounding terminal to the earth as set in the manual.
 If even one of all is unconnected by mistake or accident, it will be
much more dangerous for human than the NO-RELAY case,
because leaking current inevitably goes through the body.
 Even though all the bonnets of the loads have been grounded to the earth,
the bonnet grounding terminal should be grounded to the earth.
 Grounding should be made after the engine is stopped.
 Whenever the Earth leakage breaker is activated, you should always repair
the leaking place first of all.
