Installation
Connect the electrical power
The motor size determines the full load amperes, the overload settings, and the wire sizes. Refer to your pump
model in the
Pump specifications section or to the system schematic drawing.
1. Connect electrical power to the primary circuit breaker. The breaker is labeled on the technical drawing and
in the electrical enclosure as CB-1.
2. Attach a ground leg to the grounding lug in the electrical enclosure.
Use this table to find the minimum cross-sectional area of the external copper ground leg.
CAUTION
HyPrecision pumps can leak up to 160 mA. To reduce the effects of a high leakage current,
connect the pump to a dedicated supply transformer that has separate windings.
Use electrical parts that are certified by national or local electrical codes.
Hydraulic, water, and electrical connections can become loose during shipping and normal
operation. We recommend examining all connections at installation and during regular
maintenance.
