Installation Guide Model Information 3. Use Figure 1 above or the diagram on the inside of the enclosure lid to connect input power to the L1, L2, and N terminals of TB1 (10 to 18 AWG). A connection to the L2 terminal is only necessary on units that have relay. For multiple box installations refer to Figure 2. The neutral connection from the service panel to the N terminal of TB1 must be a permanently connected, unswitched connection. If S terminal and Li terminal are sourced from different breakers at supply panel size neutral wire accordingly TS will accept up to 10 AWG wire. 4. Locate the grounding screw on the enclosure base and attach a ground wire to this point. 5. Motor leads M1 and M2 should be terminated to the M1 and M2 terminals on TB1 if applicable. 6. For installations that have tank gauging equipment the circuit will energize the ATG terminal of TB1 when a dispenser signal is detected. The ATG terminal will be the same voltage and phase as the power supplied to the L1 terminal. It may be necessary that the phase of L1 (TB1) match the phase of the power supplying the ATG device in order to prevent cross phasing which may damage the input on some ATG equipment. 7. The return wire from the ATG device should be connected to the S terminal on TB1. The S terminalis the coil of the relay with the other side of the coil terminated to the N terminal on the circuit board. The coil rating of the relay is 4 VA at 120V or 240V, depending on model. For installations with the puma control relay in a different enclosure utilize the ATG terminal of TB1 to energize the coil. This output is rated 1A at 250V and fuse protected for these applications. See Figure 3. For installations without external control connections a short jumper wire (minimum 18 AWG) must be placed between ATG and S terminals of TB1 so that the dispenser isolation circuit can energize the relay on circuit board. 8. Terminate up to eight dispenser signals for the same petroleum product to T132. Each dispenser should have its own hot and neutral leads terminated as shown on the diagram. TB2 can accept 14-28 AWG wire. 9. After all dispenser signal leads have been connected to TB2 replace the lid on the enclosure. At this time the control box with, dispenser isolation can be energized. The neon indicator on the side .of the enclosure will illuminate once the device is poweted. A simple test to verify functionality is to operate all dispenser handles that are tied to the box and check the output for energizing. 3
