7 Installation
WARNING
To avoid fire or shock hazard, the electrical power must be
turned OFF before and during installation.
• Refer to the technical data and installation information on
the front and side mounted nameplates of the control
unit.
•
For Class I, Zone 1 installations, Series 8008/2 control
and load switch must be installed in a Certified Increased
Safety 'eb' enclosure. When installing the control
components into 'eb' enclosures the spacing distances
through air and over surface, in accordance with
CAN/CSA C22.2 No. 60079-7 + C22.2 No. 14 for
Canada or ANSI/ISA 60079-7 + UL508A for USA, must
be maintained.
••••
For Class I, Division 2 installations Series 8008/2 control and
load switch must be installed in a suitable enclosure providing
mechanical protection, provisions for conduit/cable entry, and
sufficient clearance for electrical connections as per C22.2 No.
14 for Canada and UL508A for USA.
••••
Series 8008/2 control and load switch have been Certified as
a component and the suitability of the final assembly is to be
determined by the authorities having jurisdiction.
••••
The terminals on the control component have been identified on the
control unit. Refer to the device label and technical information for
proper connection.
••••
Field wiring conductors shall be copper wires only, stranded –
and sized based on the conductor rated for 75°C.(for North
American Installations)
••••
Per NEC 505.7(E), the short circuit current needs to be limited to
less than 10,000 rms symmetrical amperes.
8 Maintenance
WARNING
To avoid electrical shock, fire and/or explosions, always
disconnect primary power source before inspection,
service or Maintenance.
•
We recommend an Electrical Prevention Maintenance program
as described in the National Electrical Code® (NEC) and the
National Fire Protection Association Bulletin NFPA No. 70B
or the Canadian Electrical Code (CEC) respectively, and any
local regulations. It is recommended that it should be at least once
a year.
••••
Maintenance should only be performed by qualified and
experienced personnel.
••••
Perform visual, electrical, and mechanical checks on all
components on a regular basis.
••••
Visually check for undue heating evidence by
distortion of wires or other components,
damaged or worn parts.
••••
Electrically check to make sure that all connections are
clean and tight.
••••
Mechanically check that all parts are properly assembled,
and operating mechanisms move freely.
••••
The Flameproof joint CANNOT be repaired
••••
Replacement parts are available through R. STAHL
distributors. Replace only with parts of identical rating
