1.1 Description

The base of the lighting contactor has provisions to accept power poles at positions "1" to "6". Provisions are also provided for up to 2 "NO" and 2 "NC" auxiliary contacts.

1.2 Installation

1. Remove all packing material from the base and all the kits.
2. Contactor must be mounted in the vertical position on a sturdy support.
3. Additional over-current protection may be required. Refer to the National Electrical Code or local electrical code as required.
4. Refer to Section 5.3 and Table D on page 3 for the wire size and the required torque for the coil terminals.

Hazardous Voltage Warning: Disconnect all power before working on equipment. Electrical shock will cause severe injury or death.

Tension Dangereuse: Coupez l'alimentation avant travailler sur le produit. Electrocution peut causer de sévères blessures ou la mort.

2 POWER POLES: C320PRP1 & C320PRP2

2.1 Description

Power poles are available in both single pole (C320PRP1) and double pole (C320PRP2) versions. A maximum of twelve poles may be installed on the base. Positions "1" to "4" on the base can be configured as either normally open “NO” or “NC” while positions “5” and “6” can be configured as “NO” only.

2.2 Removal and Conversion of Power Poles

1. If installed, ensure that all power is disconnected.
2. For multiple possible configurations of the power poles, refer to Table A below.
3. Remove block by using a screwdriver to pull the clip as shown (see Figure 2). Rotate block 180 degrees to convert from NO to NC or from NC to NO and install per 2.3 below.

Standard Catalog #: C30CNE43A0

2.3 Installation of Power Poles

1. Check moving carrier to assure free movement.
2. Install the block by sliding foot into slot, using a screwdriver, pull the clip, and position block onto base. Release the clip.
3. Check for the lettering on the base. "NO" should be visible if the power pole is assembled as normally open, and "NC" should be visible if it is assembled as normally closed (see Figure 3).

2.4 Wiring

Power poles can accept wires from #14 to #8 AWG (either solid or stranded) as single or combination of two wires (refer to Table B below for valid wire combination). Wire material must be copper with a temperature rating of 75 degrees C. Maximum tightening torque is 35 in-lbs.

3 AUXILIARY CONTACTS: C320AMH1 & C320AMH2

3.1 Description

The auxiliary contact blocks are available in both single pole (C320AMH1) and double pole (C320AMH2) versions. Auxiliary contacts can be added on either side of the base (see Figure 1). When added to the LEFT side of base, the auxiliary block functions as “NO”, and when added to the RIGHT side of base it functions as “NC”. Refer to section 4.3 for wiring.

4 CONTROL MODULE KITS

4.1 Description

Control module kits are available both for 2-wire and 3-wire control with a wide range of control voltage inputs. Figure 4 shows the components in 2-wire control module kit. A 3-wire kit includes an additional single-pole auxiliary contact block. Refer to the Ordering Detail section for more information on control module kits and control voltages available.

IMPORTANT: The control module kits are for use with the coils up to 277 VAC maximum. Use a control power transformer for higher voltages.

Conversion from an electrically held to a mechanically held type is possible by adding a “control module kit" to the base.

4.2 Installation

1. Disconnect all power and mount the control module on the contactor as shown in Figure 1 (3-wire control type).
2. Mount the latch as shown in Figure 5.
3. Be sure the latch is firmly in place with the wire facing out and the slot positioned with tab inserted.
4. Mount the latch cover as shown in Figure 5.
5. For 2-wire control, the auxiliary contact block is assembled to the right side of the base for "NC".
6. Operate contactor manually, using manual operation tabs (See Figure 5) on side, prior to installing cover to insure correct installation.

Caution: Once latch cover has been installed, it may not be removed. Ensure latch is properly installed prior to installing the latch cover.

IMPORTANT: Latch and electronic module must be used together to ensure proper operation. Failure to do so will void warranty.

4.3 Wiring

Control module's and auxiliary contact block's terminals can accept a single wire from #22 to #12 AWG (either solid or stranded). Maximum tightening torque required for the control module's terminals is 5 in-lbs. Auxiliary contact block terminals can accept parallel conductor size combinations utilizing torques identified in Table C.

5 COIL KITS

5.1 Description

A wide range of coils is available for both electrically held and mechanically held lighting contactors. Refer to the Ordering Detail section for more information about the coil kit catalog numbers and voltages available.

Note: For mechanically held lighting contactors, only use coils rated up to 277 VAC maximum. Use a control power transformer for higher voltages.

5.2 Installation

1. Disconnect all power. Replace and mount the coil on the contactor as shown in Figure 7.
2. For mechanically held contactors, remove all wires from the control module and remove the coil cover along with control module.

5.3 Wiring

Coil terminal can accept wires from #18 AWG to #14 AWG (either solid or stranded) as single or combination of two wires (Refer to Table D below for valid wire combination). Wire material must be copper with a temperature rating of 60 or 75 degrees C. Maximum tightening torque is 15 in-lbs.

Follow the schematic (Figure 6) to wire the 2 and 3-wire control modules.

Note: For 2-wire control, ensure the two wires coming from the control module are connected across a NC auxiliary contact.
