Product Information

The Ceiling Mounted Light is a lighting system designed for medical facilities. It is available in both Halogen and LED styles. The product is suitable for use with Models 153637 (-001) and 153905 (-001). The maximum weight capacity of the lighting system is 70 lbs (31.7 kg).

Installation Note

It is recommended to mount the light on the opposite side of the doctor’s normal work position.

Equipment Alert

The orientation of the ceiling plate is crucial to ensure proper range of motion. Rotate the ceiling plate until the strain relief bracket is positioned as shown.

Ceiling Support Structure

Note that Midmark does not supply the ceiling support structure.
Consult a qualified professional to install the appropriate support structure for your facility. The illustrations provided in the manual are for suggestion only.

Ceiling Plate Deflection

The ceiling structure must support the light system without deflection. To prevent the suspension arm from drifting, the ceiling plate must deflect no more than 1/16 in (1.6 mm) over a 12 in (30.5 cm) distance.

Product Usage Instructions

Step 1: Mounting the Light

1. Choose the appropriate side to mount the light, opposite to the doctor’s normal work position.
2. Rotate the ceiling plate until the strain relief bracket is positioned as shown in the illustrations.
3. If using a wood frame ceiling, follow the suggested installation method using joists and nails or consult a qualified professional for guidance.
4. If using a suspended ceiling, refer to the provided illustration for the suggested ceiling support structure using metal masonry anchors and bolts.

Step 2: Power Supply

1. Ensure a suitable power supply is available near the installation location.
2. Connect the light system to the power supply following the manufacturer’s instructions.

• B) Mark three mounting holes and power line hole.
• C) Drill holes.

Note
The customer must provide the wiring to power the lighting system. The lighting system requires 115/230 VAC input voltage. Wiring should be two conductor w/ground, 14 gauge copper, rated for 300 VAC (mini-mum). Connect and route wiring according to state and local codes.

Step 2: Routing power line.

• A) Route power line thru ceiling access hole.
• B) Pull power line thru strain relief bracket on ceiling plate.

Step 3: Secure ceiling plate.

• A) Align ceiling plate to ceiling support structure.
• B) Secure ceiling plate via 1/2” holes with appropriate hardware [not provided].

Step 4: Wiring Installation.

• A) Use label for insert wires from power line into terminal block.
• B) Secure wires with terminal block screws.

Equipment Alert (Halogen ONLY)
If ceiling light unit is being powered by 230 VAC (nominal), disconnect wire from 115 VAC transformer terminal
and reconnect to 230 VAC transformer terminal.

Step 5: Securing power line to ceiling plate.

• A) Secure facility power line to ceiling plate with cable clamp.
• B) Tighten strain relief screw(s) to secure power line.
