Wiring
(ALL WIRES TO BE COPPER WITH MIN. TEMP. RATING OF 60° C)
The motor thermostat automatically resets when the motor cools. You
are responsible for latching this signal to inhibit operation after a motor
thermostat fault. Connect thermostat using twisted pair wire.
The PSR4/5 fault contacts (rated 115 VAC 1 amp) must be wired in
series with the overload relay. On 12 & 20 amp PSR4/5s, this contact is
normally open and closes within 250 ms after application of control and
main power. This contact opens in fault conditions. On 50&75 amp
PSR4/5s, this contact closes on application of control power and opens
in fault conditions.
Resistor is connected to high voltage. Ensure sufficient electrical
clearance when mounting. Resistor may become very hot during
operation.
Do not
mount near materials that are flammable or damaged
by heat. Ventilation may be required. See wiring drawing for specific
regen resistor kit. Each kit has different series/parallel resistor
connections to obtain specific resistance and power rating.
Wire sizes, breakers and fuses for PSR4/5:
•
PSR4/5-X12 has a max main power input current of 12 A
RMS
.
•
PSR4/5-X20 has a max main power input current of 20 A
RMS
.
•
PSR4/5-X50 has a max main power input current of 50 A
RMS
.
•
PSR4/5-X75 has a max main power input current of 75 A
RMS
.
The actual application may require less current. Use 600 VAC insulated
wire and refer to local electrical codes for proper wire size for the
currents listed above. Fuses for main power should be a U.L. rated time
delay type, such as, buss FRN-R series.
The power BUS between a PSR4/5 and BOS4 should use the following
wire gauge with 600 VAC insulation:
•
PSR4/5-X12, 14 AWG (or larger) wire.
•
PSR4/5-X20, 10 AWG wire.
•
PSR4/5-X50, 8 AWG (or larger) wire.
•
PSR4/5-X75, 8 AWG (or larger) wire.
All signal and control wires must be 22-18 AWG wire. The crimp
terminals for 22-18 AWG wire are supplied for use with BDS4
connectors C1, C2, C3, C4, option connector and PSR4/5 connectors
C1 & C2, for 16 AWG wire use Molex #39-00-0078 terminals.
In the BDS4 3 amp thru 20 amp and the PSR4/5 12 amp and 20 amp,
the screws in the power terminal blocks are captive.
DO NOT
attempt to
remove them to use ring terminals. Use locking spring spade terminals
such as Hollingsworth #XSS20954S or #SS20947SF for 16 AWG wire
and #XSS20836 or #SS20832F for 12/10 AWG wire.
All AC lines should be twisted cables.
