ACROSS-THE-LINE START

NOTES:

1.Field wiring to be in accordance with the current edition of the National Electrical Code as well as all other applicable codes and specifications.

2.Numbers along the right side of a diagram are line identification numbers. The numbers at each line indicate the line number location of relay contacts. An unlined contact location signifies a normally closed contact. Numbers adjacent to circuit lines are the circuit identification numbers.

3.Any customer supplied contacts must be suitable for switching 24VDC. (Gold contacts recom- mended.) Control Wiring must not be run in the same conduit with any line voltage wiring.

4.To cycle unit on and off automatically with contact shown, install a cycling device in series with the flow switch (FSLW). See Note 3 for contact rating and wiring specifications. Also refer to cautions on the following page.

5.To stop unit (Emergency Stop) with contacts other than those shown, install the stop contact between 5 and 1. If a stop device is not installed, a jumper must be connected between terminals 5 and 1. De- vice must have a minimum contact rating of 100VA at 115 volts A.C.

6.Alarm contacts are for annunciating alarm/unit mal- function. Contacts are rated at 115V, 100VA, resis- tive load only, and must be suppressed at load by user.

7.See Installation, Operation and Maintenance Manual when optional equipment is used.

8.Control panel to be securely connected to earth ground.

9.Us 2KVA transformer in optional transformer kit un- less there are optional oil separator sump heaters which necessitates using a 3KVA transformer.
