High starter currents can potentially damage your key switch and panel circuits over time. High current failures are not
warrantable failures!
As such, the engine/ starter wiring, on all LOFA CP620 installations must include a starter relay to minimize current
through the key switch.
General Starter Relay Specifications

LOFA provides suitable heavy duty relays and generic starter relay wiring kits in both 12v and 24V; please contact your
LOFA reseller for more information.
Mounting-Panel
The LOFA CP620 Panel design allows much design flexibility with respect to mounting position. However, generally
speaking, the CP620 must be mounted in such a manner so as to provide ergonomic Operator access, minimize
vibration on the panel, minimize and/or prevent water/coolant/oil/fuel ingress, prevent overheating of the panel, and
facilitate good wiring harness runs.
In order of preference, LOFA CP620 Panels may be mounted as follows:
1.
Remote from the engine and engine frame on a suitable rigid bracket system.
2.
Remote from the engine and affixed to a bracket system attached securely and rigidly to the engine/
equipment frame or base.
3.
Directly to the engine using either the horizontal or vertical mounting face of the LOFA CP620 mounting
bracket. The engine mounting bracket system/design must be very rigid, prevent relative motion between
the panel bracket and the engine, and be affixed as close to the crankshaft centerline as possible—
preferably near the engine flywheel housing.
Regardless of mounting position:
•
The mounting bracket may not be subjected to excessive acceleration/ vibration in any direction.
•
Under no circumstance may the panel/ panel system be subjected to resonant vibrations/ oscillations.
•
The panel must be mounted so as to be generally protected from the possibility of direct water, coolant, and
fuel or oil exposure.
•
The panel must be positioned so as to avoid direct water or rain intrusion during operation or transport.
•
Wire/ harness connections to the panel may not prevent or minimize vibration isolation system effectiveness.
•
Wire/ harnesses must be installed with very liberal bending radii and should be protected from oil, fuel, and
abrasion.
•
Panels must not be mounted near exhaust system components or in areas that would result in excessive
panel/panel component temperatures.
