Original instructions
Connecting the Electrical Supply Source
to the Protector Fume Hood
Prior to connecting any electrical wiring to the fume hood structure, refer to the
hood identification plate for the proper electrical requirements of your specific
model.
WARNING: The building electrical supply system for
Protector Hoods is required to include overload protection. A
switch or circuit breaker shall be in close proximity to the
equipment and within easy reach of the operator. The switch or
circuit breaker is to be marked as the disconnecting device for
the equipment.
AVERTISSEMENT : Le système d’alimentation électrique de la
Hotte Protecteur doit inclure la protection contre la surcharge. Un
commutateur ou disjoncteur doit être tout près de l'équipement et à
portée facile de l'opérateur. Le commutateur ou le disjoncteur doit
être marqué comme l'appareil débranchant pour l'équipement.
The identification plate, model number, serial number, and electrical connection
boxes are accessible from the front of the fume hood by removing the front panel.
The Protector Perchloric Acid Hood is normally wired for 115 Volt, 50/60 Hz, 20
Amp or 230Volt, 50/60 Hz, 10 Amp electrical service. Check the I.D. plate behind
the front panel for voltage verification. The number of circuits varies depending on
the model. All of the electrical connections are terminated at the field wiring
terminal box for hook-up by a qualified electrician. We recommend each circuit
be a dedicated branch circuit. However, if wired together the maximum load
allowed is the sum of individual outlets plus the rating of the unit (i.e. 2 Amps
remote, 8 Amps integral blower) not to exceed the 10A or 20A electrical service.
The single point internal junction box is used for the connection of the lights,
blower, and duplex outlets. Refer to the wiring diagram for your Protector
Perchloric Acid in Appendix C: Protector Perchloric Acid Specifications.
The fume hood is required to be grounded to the MAINS protective earthing ground
for safe operation. Using a ring terminal sized for a 10-24 machine screw, connect the
MAINS ground conductor to the grounding lug marked with the protective earthing
symbol, . Only MAINS ground conductors should be connected to the protective
earthing ground lug, no other conductors should be connected to this grounding lug.
Using wire nuts connect the MAINS supply conductors to the fume hood supply
wires. Insure that the wires are connected as per the appropriate wire color codes for
the input voltage. For 115V Phase (Hot) is black and Neutral is white, for 230V
Phase1 is brown and Phase2 is blue. Refer to the wiring diagram for your Protector
Perchloric Acid in Appendix C: Protector Perchloric Acid Specifications.
