Use copper wire with 60°C or 60/75°C insulation for all
line voltage connections. Observe all safety regulations.
Electrical wiring should be performed in accordance with
all applicable national, state, and local codes to prevent
damage to the instrument and ensure personnel safety.
Connector Labeling
The connectors label, affixed to the instrument, shows the location of all
connectors available with requested configuration. See Figure 2, page

connection. The + and - symbols are only a suggested wiring convention.
Signal Connections
Input signal connections are made to a 14-terminal connector at
terminals labeled INPUT CHANNELS. The COM (common) terminal is
the return for all input channels.
Normally Open (NO) or Normally Closed (NC) Switches
All channels are initially set for normally open contacts. Each contact is
wired across an input channel and common.
Relays and 24 V Output Connections
Relay connections are made to a six-terminal connector labeled
RELAY1, RELAY2. The COM (common) terminals of the relays should
not be confused with the COM (common) terminal of the signal
connector. The 24 VDC output is available at the connector labeled 24V
OUT, next to the relays connector.
