Chapter 2 Installation and Wiring
Installation Precautions
The following precautions are provided as guidance for proper installation of
this controller. Because this product was designed to be used in a variety of
applications, not all precautions mentioned are relevant to your particular
application. In all cases, the local codes and standards governing this type of
product must be observed.
Motor Branch Protection and Disconnecting Means
• The controller features motor overload protection. However, it does not
have means to protect itself from a short circuit condition. Suitable
branch circuit protection and coordination must be provided per the
NEC, or the equivalent local electrical code.
Electrical Noise Suppression
• Electrical noise can be generated from various sources connected to the
same power as the controller. Sources of noise include: inductive loads
(example: relays and solenoids), large motors, and machinery, variable-
frequency drives, and other high-frequency devices (example: welders).
• Electrical noise can enter the product through power and control wiring
and cause damage to solid-state components.
• You can mitigate electrical noise using the following methods:
- Proper wiring practices, including grounding, use of shielded cable
where appropriate, and separation of power, control, and signaling
wires.
- Use surge suppression devices on inductive loads.
- Use isolation transformers for high-frequency generators.
Power Factor Correction Capacitors (PFCCs)
• PFCCs must always be used on the line side of the controller. Use of
PFCCs on the output side of the controller damages the starter.
