Installation Guidelines of DPG-2201-002

Mounting Type

The Woodward DPG-2201-002 is a panel-mounted digital speed governor designed for flush installation on cabinet doors and control panels. It supports direct front operation, parameter checking and on-site troubleshooting, with a compact size and no requirement for DIN rail mounting parts.

Pre-installation Preparation

Select installation locations with adequate heat dissipation, away from severe vibration, high humidity, corrosive gas and strong electromagnetic interference. Cut a standard panel opening per product dimensions and clean the mounting surface to remove debris and burrs. Completely power off the system before installation to ensure operational safety.

Step-by-Step Installation Procedures

Insert the controller through the front of the panel cutout until the front panel fits flush with the cabinet surface. Secure the device with matching rear mounting brackets and fasten the screws evenly to prevent looseness under vibration. Connect power, sensor and communication cables strictly per official wiring diagrams, and tighten all terminals firmly.

Wiring & Installation Specifications

Separate low-voltage signal cables and high-power cables to minimize electromagnetic interference and ensure stable signal collection and device operation. Crimp terminals securely and reserve appropriate cable length to avoid tension damage. Maintain neat and standardized internal wiring for convenient inspection and maintenance.

Dismounting Steps

Fully cut off system power and verify safety before disassembly. Disconnect and mark all power and signal cables. Loosen the rear fixing screws and brackets, then push the controller forward to remove it from the panel cutout.

Installation Environment Restrictions

Reserve sufficient ventilation space for heat dissipation; do not install the unit in fully sealed and poorly ventilated enclosures. The allowable operating ambient temperature ranges from -40 °C to +85 °C, with 5%–95% non-condensing humidity. Avoid long-term exposure to strong vibration and impact environments to protect internal components.
