4.1 ELECTRO-STATIC DISCHARGE (ESD) RECOMMENDATIONS
• Before making wiring connections, discharge any static electricity from
your body before touching circuit boards and other internal components
by touching a grounded metal object to remove any charge from your
body.
• When making wiring connections, make sure to remain properly grounded
by wearing an ESD wrist strap or similar device.
4.2 CUSTOMER-SUPPLIED ELECTRICAL EQUIPMENT
The Aqua Con TROLL process controller module requires AC line power.
The following user-supplied wires are also required:
• Current sensor wires (24-18 AWG)
• AC relay wires (14 AWG)
• For hard-wired locations using conduit, a 100-240 VAC source with over
current/disconnect protection will be provided by the end user.
• For cord-connected plug and socket locations, approved suitable wiring to
be provided by the end user.
4.3 ENSURING GOOD ELECTRICAL CONNECTIONS
To ensure that all sensors and power sources function properly, make sure
that:
• Each individual wire is stripped and tinned to ¼ in.
• Each wire is tightly screwed into the terminal strip.
• Each wire, not the plastic jacket, is touching the terminal strip. Clip or cap
any unused wires.
