ELECTRICAL CONNECTIONS
It is advisable to leave the control box off the sub-base while com-
pleting the electrical connection to the burner.
1) Wire access hole (Use BX electrical connector)
2) Earth ground conductor terminal (Green wire)
3) Hot conductor terminal (Black wire)
4) Neutral conductor terminal (White wire)
5) Strain relief clamp
The burner may be controlled using either a DIRECT LINE VOLT-
AGE control circuit (120V AC 60 cycle) OR:
- a LOW VOLTAGE thermal input (T-T) if the primary control 530SE/C 24V is used;
Using the appropriate diagram below, make electrical connections to burner. All wiring must be done in accordance with
existing electrical codes, both national and local.
When all electrical connections have been made, the control box may be put back in place on the sub-base.
NOTE: Terminal 4 is to be used to activate a remote safety lockout circuit only. A 120V AC source is supplied to Terminal
4 upon lockout. The maximum allowable current draw for this circuit is 1 AMP.
IMPORTANT: if a neutral or ground lead is attached to Terminal 4, the control box will be damaged should lockout occur.
WARNING:
The hot (black) wire must be connected to the L terminal and the
neutral (white) wire must be connected to the N terminal or the
primary safety control will be damaged.
Do not connect wither wire to the terminal marked
.
WARNING: DO NOT activate burner until proper oil line connections have been made, or failure of the pump shaft
seal may occur.
