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 qualied 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 conrm power is o.
• Replace all devices, doors and covers before turning on power to this
equipment.
• This equipment must be eectively grounded per all applicable codes.
Use an equipment-grounding conductor to connect this equipment to the
power system ground.
• Conrm 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. Conrm that the unit has the same voltage rating and conguration 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.
