10 Electronic Bypass Controller Installation and Commissioning Guide
2.5 Wiring and Precautions
2.5.1 General
1. DO NOT connect or disconnect wiring or perform signal checks while the power
supply is turned ON.
2. Connect the power supply wiring to the electronic bypass input terminals L1, L2
and L3 on the main circuit disconnect device.
3. Connect the motor wiring to the bypass output terminals T1, T2 and T3 at the
Class 10 Motor O/L or the output reactor if installed.
4. Never touch the output circuit directly or place the output line in contact with the
package enclosure.
5. DO NOT connect power factor correction capacitors on the output circuit.
6. Power supply wiring and motor wiring must be in separate conduits with separate
ground conductors. (DO NOT use conduits as ground).
7. Control wiring must be in conduit separate from both power supply and motor
wiring.
8. Tighten the screws on the main circuit disconnect (if provided) and control circuit
terminals.
9. Observe national and local codes when wiring electrical devices.
Failure to observe these precautions may result in equipment damage or improper
operation and may not be covered under warranty.
2.5.2 Input Wiring
The electronic bypass package may be supplied with several different input device
options. These input options include protective devices as well as non–protective
devices. It is the responsibility of the installing parties to ensure that requirements
for branch circuit protection of the appropriate size and location are observed. All
incoming power is connected to terminals L1, L2, and L3. The following input options
are available.
• Fused disconnect
• Circuit breaker
• Input line reactor
• Input RFI lter
