2.8 Electrical Connections
All power connections are made through the conduit thru-holes in the upper left
side of the instrument. The instrument is shipped with an oil-tight seal in the
uppermost hole and plugs in the middle and lowest hole. Wire the instrument for
power and relay connections using NEMA-approved conduit fittings.
The middle hole is intended for wiring of the relay and the lowest hole is intended
for connecting power to the instrument. If relay connections are not made through
the middle hole, an oil-tight seal must be installed in place of the plugs to maintain
the IEC 529 IP62 rating. See REPLACEMENT PARTS.

2.8.1 Power Connections
Power connections are made at the terminal strip located in the left side of the
electrical compartment and are accessible when the customer access cover is
opened. See Figure 10.
For process or industrial applications, the national electrical codes of most
countries require that AC service feeds be hard-wired and contained in
conduit systems. The SP-510™ Hardness Monitor has been designed to conform
to this requirement.
