Dry pit attachment need to be grounded. However, regular installation
automatically ground the equipment so no additional grounding is required by
the customer. But if oil tank and oil separation pit is made of resin whose
grounding resistance is extremely high, dry pit attachment needs additional
grounding because it may sometimes cause misinformation. (when the
grounding resistance is
≦
1
Ω
