Technical Data
WIRING DIAGRAM (YCAS0358EB-0418EB AND YCAS1065EB-1215EB)
ACROSS-THE-LINE START AND WYE-DELTA START
NOTES:
1. Field wiring to be in accordance with the current edi-
tion 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 indi-
cate the line number location of relay contacts. An
unlined contact location signifies a normally closed
contact. Numbers adjacent to circuit lines are the cir-
cuit identification numbers.
3. Any customer supplied contacts must be suitable for
switching 24VDC. (Gold contacts recommended.) Con-
trol 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 page 101.
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. Device 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, resistive
load only, and must be suppressed at load by user.
7. Control panel to be securely connected to earth ground.
8. Us 2KVA transformer in optional transformer kit un-
less there are optional oil separator sump heaters which
necessitates using a 3KVA transformer.
