S&C Instruction Sheet 659-555

Communications Signal

Reference Requirements

All communications systems that interface with the PureWave
SMS-250 equipment must be designed for operation in a
multipoint earth (ground) reference system.

See examples of ground plan diagrams in Figures 7 and 8.

Control and Grounding Connections

For control and grounding connections:

STEP 8.

Install control and communication cabling using
the entry location in the cable termination area.

STEP 9.

Attach the ground bus of the PCS to the system
ground in accordance with the installation drawing.

STEP 10.

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
system. 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 4 for torque requirements.

Base Covers

Install the base covers (if not already installed) at the front
and back forklift entries of the enclosure. They are typically
stored on the inside of the enclosure door. See Figure 9.
