Note: J5 is accessible with the cover on.
Keypad may be plugged in or removed
while control is ON. If remote keypad is
plugged into J5, the main keypad is
automatically disabled.

AC Line Connections
Be sure all power to the control is disconnected before proceeding. If power
has been applied to the control, wait at least 5 minutes after power disconnect
for residual voltage across the bus capacitors to discharge.
Reduced Input Voltage Derating
All power ratings stated in Section 6 are for the nominal AC input voltages
(115, 230, or 460). The power rating of the control must be reduced when
operating at a reduced input voltage. The amount of reduction is the ratio of
the voltage change.
Examples:
A 5hp, 230VAC control operating at 208VAC has a reduced power rating of
4.52hp.

Likewise, a 5hp, 460VAC control operating at 380VAC has a reduced power
rating of 4.13hp.

Power Disconnect
A power disconnect should be installed between the input power service and
the control for a fail-safe method to disconnect power. The control will remain
in a powered-up condition until all input power is removed from the control and
the internal bus voltage is discharged.
