Failure to follow the Safety Warning Instructions may result in electric shock, fire or explosion. Do not fuse neutral or grounded conductors. Note: See section V, Fusing, on page 10. A separate AC line switch, or contactor, must be wired as a disconnect switch, so that the contacts open each ungrounded conductor. -
Page 12: Fusing
Note: If an isolated signal voltage is not available, an optional signal isolator (Camco P/N 99A61455000000) should be used. FIGURE 6 – ANALOG VOLTAGE Connect the isolated input voltage to CONNECTION terminal P2 (positive) and P1 (negative). -

WARNING! Do not adjust trimpots with main power on if possible. If adjust- ments are made with power on, insulated adjustment tools must be used and safety glasses must be worn. High voltage exists in this control. Electrocution and/or fire can result if caution is not exercised. Safety Warning on page 2 must be read and understood before proceeding. - Page 20 C. Overload Indicator (OL) – When the motor is loaded to the current limit setpoint (CL set- point is established by the setting of jumper J1 and the CL trimpot) this lamp will glow RED. If the OL indicator remains lighted during control operation, a fault condition may exist.
