Wiring Instructions - Flowserve Accord WS/WM Ultraswitch User Instructions

6.1 Wiring instructions

• Perform all wiring according to the
wiring diagram found on the label
in the housing (see picture) and
instructions given below.
• Make sure that the ground wire is
correctly connected
• Seal unused entries with proper and
suitable conduit plugs.
The WS/WM Ultraswitch™ enclosures feature
pre-wired switches. All user connections are made
at a numbered terminal strip. Both external and
internal grounding locations have been provided
for use in installation. A wiring diagram is located
on the product label and indicates which terminal
number corresponds to which switch contact:
normally open, normally closed, common, etc.
Follow the wiring diagram, and electric code to
connect switches to your system.
For field wiring: ensure that any excess wire lengths
or loops are routed away from any moving parts
and are short enough, or secured to ensure a 1/4"
clearance between the wire and the inside surface
of the switchbox cover.
Note: for all magnetically tripped proximity swit-
ches, the top switch should only be used to indicate
the clockwise position: the bottom switch should
only be used to indicate the counter-clockwise
position. Any deviation from these settings may
result in erratic indication.
Solenoids may also be wired through the WS/WM
Ultraswitch™ enclosure. At least two auxiliary
terminals are included as standard. Wire the so-
lenoid to auxiliary terminals, then connect power
leads to the opposite terminal side. Be sure to
properly ground the solenoid at the provided
ground terminal.
WS UltraSwitch™ Series enclosures include two
1⁄2" NPT conduit entries and the WM Series inclu-
des two M20x1.5 conduit entries.

Caution!
• Proper and suitable conduit plugs must be
installed in unused conduit entries before put-
ting the unit into service.
• Installation must be according to National
Electric Code, local codes, local certificates
and manufacturer's instructions in all cases.
Environmental seals must be used to protect
ingress of water through the conduits.
• Prevent electrostatic build-up for safe use. The
enclosure of the WS/WM Ultraswitch™ switch
box is made of PA6/PA66 and any impact or
friction caused by external objects should be
avoided to prevent electrostatic build-up.
