•
Routing interconnecting control wires with low voltage or neutral that cannot result in energizing the hazard
•
Locating all elements (modules, switches, devices under control, etc.) within the same control panel, adjacent to
each other, and directly connected with short wires
•
Properly installing multi-conductor cabling and multiple wires that pass through strain-relief fittings. Over-
tightening of a strain-relief can cause short circuits at that point
•
Using positive-opening or direct-drive components installed and mounted in a positive mode
WARNING: Use of Transient Suppressors
Transient suppressors are recommended. They MUST be installed across the coils of the FSDs. NEVER
install suppressors directly across the contacts of the FSDs. It is possible for suppressors to fail as a
short circuit. If installed directly across the contacts of the FSDs, a short-circuited suppressor creates
an unsafe condition.
WARNING: Safety Output Interfacing
To ensure proper operation, the Banner product output parameters and machine input parameters must
be considered when interfacing the solid state safety outputs to the machine inputs. Machine control
circuitry must be designed so that:
•
The maximum cable resistance value between the Safety Controller solid-state safety outputs
and the machine inputs is not exceeded
•
The Safety Controller’s solid-state safety output maximum Off state voltage does not result in
an On condition
•
The Safety Controller’s solid-state safety output maximum leakage current, due to the loss of 0
V, does not result in an On condition
Failure to properly interface the safety outputs to the guarded machine may result in serious
bodily injury or death.
WARNING: Shock Hazard and Hazardous Energy
Always disconnect power from the safety system (for example, device, module, interfacing,
etc.) and the machine being controlled before making any connections or replacing any
component.
Electrical installation and wiring must be made by Qualified Personnel and must comply with the
relevant electrical standards and wiring codes, such as the NEC (National Electrical Code), ANSI
NFPA79, or IEC 60204-1, and all applicable local standards and codes.
Lockout/tagout procedures may be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, ISO
14118, or the appropriate standard for controlling hazardous energy.
WARNING: Proper Wiring
The generalized wiring configurations shown are provided only to illustrate the importance
of proper installation. The proper wiring of the Safety Controller to any particular machine is
solely the responsibility of the installer and end user.
