Installation, Assembly, and Setup
Step 5

Control and Grounding Connections

For control and grounding connections:
(a) Install control and communication cabling using the
entry location in the cable termination area.
(b) Attach the ground bus of the PCS to the system
ground in accordance with the installation drawing.
(c) Seal the conduits with duct-sealing compound to
prevent water from entering the system through the
conduits.

Connection Checks

Check all field-installed cables and wiring to the power
conversion system by performing a "point-to-point" check
on all of the wiring to verify the system is wired, labeled,
and terminated per drawing PEA-1610-4-IN and any
project-specific drawings supplied with the PureWave
SMS-250. Note any problems found and corrective actions
applied.

Torques

Check all factory and field-bolted electrical connections
inside the PCS enclosure and verify they are torqued to
the proper tightness. See Table 1 for torque requirements.
