4. Secure the inserted wires by tightening the connector screws.
5. Insert the J1 and J4 terminal connectors back on the barrier board.

Applying power to the LevelMaster

After completing all the wiring and securing the wires in the terminal connectors, it is important to verify that the wiring was done
correctly and that the LevelMaster(s) can be powered.
To apply power and verify wiring:
1. On the host controller, ensure that the COM terminal connector is inserted back into the host controller board. If the host
controller is powered, the COM port power pins have output power.
2. On the first LevelMaster, insert the power connector back into the board. This applies power to the LevelMaster.
3. Verify that the power LED (labeled D9 and located below the power connector) is not lit. If it is lit, it indicates that the wrong
polarity has been used and it must be rewired to correct polarity.
4. Verify that the power LED does not light in additional LevelMasters that may be connected.
5. When verification of wiring is complete, remove the power connector from the LevelMaster electronic board and proceed to
ground (section 4.7) or configure (section 5) the unit.
IMPORTANT NOTE: The LevelMaster can not be connected to the controller while being configured using
MasterLink as there is only one communication port available. The power connector can be reconnected once
configuration is complete and local communication cables are removed.

Grounding

WARNING – Bodily injury/ property damage. Grounding the LevelMaster in a hazardous location must meet the
requirements as specified in the National Electrical Code (NEC) or the Canadian Electrical Code (CEC).
If an earth ground is available, ground the electronics board as follows:
1. Connect the EARTH connector to the ground connector as shown in Figure 35.
2. Jumper pins 2 and 3 on J12.
