Installation & Commissioning Guidelines
Prior to mounting, visually inspect the module casing, terminal blocks and circuit board for any physical damage. Confirm compatibility with the existing DEIF genset controller architecture before wiring commences.
All installation work must be performed with power disconnected. Anti-static precautions are required to avoid damaging internal electronic components. Secure the module firmly onto the DIN rail to prevent shifting caused by mechanical vibration.
