The FOS Hydor 120W RGBL is a professional stage lighting fixture. This manual provides essential safety, installation, and operational guidelines. Key points include ensuring proper grounding (Protection Class 1), maintaining a minimum distance of 1 meter from surfaces and 0.5 meters from flammable materials, and ensuring the fixture is installed by qualified personnel only.

Safety Precautions
- Grounding: The fixture must be properly grounded.
- Heat: Do not touch the housing during operation; allow 15 minutes to cool before servicing. External surfaces can reach 85°C (185°F).
- Environment: Keep at least 1 meter away from objects and 0.5 meters from flammable materials.
- Maintenance: No user-serviceable parts inside. Do not open the fixture while in use.
- Connections: Ensure all connections and end caps are sealed with dielectric grease to prevent corrosion.
Overview
The fixture features an LCD display for the system menu, DMX input/output (3-pin and 5-pin), power input/output, and an antenna for wireless control. Refer to the overview diagram for the specific location of these ports.

Installation Guidelines

- Professional Installation: Only qualified personnel should install the fixture.
- Rigging: Use only original rigging parts. Always secure overhead installations with a secondary safety attachment (e.g., safety cable).
- Environment: Ambient operating temperature range is -20°C to 45°C (-4°F to 113°F).
- Ventilation: Do not block air ventilation slots; keep fans and inlets clean. Allow 15cm (6 inches) of clearance for cooling.
System Menu
The system menu allows configuration of the following:
- Control: DMX Address (001-512), Channel Mode (12CH/22CH), Signal Select (XLR/Wireless), and Manual control.

Practical help
Common problems
This is a normal process caused by excess paint in the interior of the casing burning off from the heat; it will decrease gradually.
Check the Signal Select setting in the menu (XLR vs Wireless) and ensure DMX cables are securely connected.
Ensure air ventilation slots are not blocked and fans are clean. Check Fan Mode settings in the menu.
Before use
- Verify the fixture is properly grounded (Protection Class 1).
- Ensure the ambient temperature is between -20°C and 45°C.
- Check that all power cords and connectors are undamaged.
- Ensure ventilation slots are clear of obstructions.
- Verify that the mounting structure is certified to hold the fixture's weight.
- Apply dielectric grease to connections if exposed to moisture.
