Model 235 (Edco SHA and SHAS Series)

Surge Protective Device (SPD)

Introduction ASCO Model 235, designed for highway lighting and street pole applications,

provides surge protection for sensitive lighting ballasts and power supplies

from damaging transients. The SPD is encapsulated in a compact watertight

enclosure that can be installed inside the pole.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe

electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462.

• This equipment must only be installed and serviced by qualied electri-

cal personnel.

• Turn o all power supplying this equipment before working on or inside

equipment.

• Always use a properly rated voltage sensing device to conrm power is o.

• Replace all devices, doors and covers before turning on power to this

equipment.

• This equipment must be eectively grounded per all applicable codes.

Use an equipment-grounding conductor to connect this equipment to the

power system ground.

• Conrm that the Surge Protective Device voltage rating on the module

or nameplate label is not less than the operating voltage.

• Do not exceed 15 or 30 Amps continuous current depending on model

number

Failure to follow these instructions will result in death or serious injury.

WARNING: This product can expose you to chemicals including

DINP, which is known to the State of California to cause cancer, and

DIDP which is known to the State of California to cause birth defects

or other reproductive harm. For more information go to: www.

P65Warnings.ca.gov.

NOTICE

LOSS OF SURGE SUPPRESSION

• Make certain that Surge Protective Device is disconnected from the

circuit it is protecting before conducting high potential insulation testing.

Failure to follow these instructions can result in equipment damage.

DANGER

1. Turn o all power supplying this equipment before working on or inside

equipment.

2. Conrm that the unit has the same voltage rating and conguration as

the power system voltage and power system voltage to which it will be

connected.

3. Install the unit and cables as close as possible to the protected equip-

ment and secure.

4. Connect the supply cables to the line side of the SPD.

5. Complete the circuit by connecting cables from the load of the SPD to

the protected equipment.

6. Connect the Ground wire on the SPD to the protected equipment.

7. Check that all connections are secure. Remove all tools and discarded

hardware from the unit.

8. Replace the barrier, cover/door and/or trim to the equipment.

9. Equipment may be re-energized after all the above steps are complete.
