•
Before servicing, disconnect all power
sources and allow at least 30 minutes for
capacitors to discharge.
•
All electrical enclosures—unit or remote—
are IP2X.
•
The IPC wiring shield should be grounded
on one end only at control panel end. The
other end should be un-terminated and
taped back on the cable sheath to prevent
any contact between shield and ground.
•
Oil Pump Interlock: All starters must
provide an interlock (normally open)
contact with the chiller oil pump connected
to the control panel at terminals 1X1-10
and 1X1-21 (14 AWG; for AWG/MCM
2
equivalents in mm
, refer to the table in
"Electrical Requirements," p.
purpose of this interlock is to maintain the
oil pump signal in the event that a starter
failure, such as welded contacts, keeps
the chiller motor running after the
controller interrupts the run signal.
